AMS 5406 ROUND BAR & B-1900+HF NICKEL SUPERALLOY: MANUFACTURING, COMPOSITION, INTERNATIONAL EQUIVALENTS, STANDARDS, APPLICATIONS AND AEROSPACE MATERIAL GUIDE AMS 5406 ROUND BAR MANUFACTURING GUIDE — B-1900+HF NICKEL-BASED SUPERALLOY, PWA 1455, UNS N13010 AND HIGH-TEMPERATURE INVESTMENT CASTING AMS 5406, COMMONLY ASSOCIATED WITH B-1900 + HF (B-1900 HF), IS A NICKEL-BASED PRECIPITATION-STRENGTHENED SUPERALLOY DEVELOPED FOR DEMANDING HIGH-TEMPERATURE AND CORROSION-RESISTANT APPLICATIONS. THE SAE SPECIFICATION IDENTIFIES AMS 5406 AS AN ALLOY CASTING, INVESTMENT, CORROSION AND HEAT RESISTANT MATERIAL PRODUCED BY VACUUM MELTING AND VACUUM CASTING IN THE AS-CAST CONDITION. A CRITICAL PURCHASING AND ENGINEERING POINT IS THAT AMS 5406 ITSELF DOES NOT SPECIFY WROUGHT ROUND BAR. BUYERS SEARCHING FOR AMS 5406 ROUND BAR, AMS5406 BAR, B-1900 HF BAR, NICKEL ALLOY ROUND BAR, OR B-1900+HF ROD MAY ACTUALLY BE LOOKING FOR MATERIAL MADE FROM THE SAME ALLOY FAMILY OR FOR HISTORICAL MATERIAL ASSOCIATED WITH THE SPECIFICATION. AMS 5406 COMPLIANCE SHOULD NOT BE CLAIMED FOR A ROUND BAR UNLESS THE APPLICABLE PURCHASE SPECIFICATION AND CERTIFICATION SPECIFICALLY ESTABLISH THAT COMPLIANCE. THE ALLOY IS ALSO IDENTIFIED WITH PWA 1455 IN AEROSPACE MATERIALS REFERENCES. NASA RESEARCH IDENTIFIES CAST PWA 1455 AS B-1900 + HF, WHILE INDUSTRIAL VACUUM-MELT REFERENCES ASSOCIATE B-1900 + HF WITH AMS 5406 AND PWA 1455. WHAT IS AMS 5406? SAE AMS 5406 DESCRIBES: ALLOY CASTINGS, INVESTMENT, CORROSION AND HEAT RESISTANT — 63NI-8.0CR-10CO-6.0MO-1.0TI-4.2TA-6.0AL-0.015B-0.03ZR-1.2HF, VACUUM MELTED, VACUUM CAST, AS CAST. ITS SCOPE COVERS A CORROSION AND HEAT-RESISTANT NICKEL ALLOY IN THE FORM OF VACUUM-MELTED, VACUUM-CAST INVESTMENT CASTINGS. THE HISTORICAL SPECIFICATION SEQUENCE IS: HISTORICAL STATUS AMS 5406: SUPERSEDED AMS 5406A: SUPERSEDED AMS 5406B: CANCELLED / NONCURRENT PWA 1455: ASSOCIATED AEROSPACE DESIGNATION B-1900 + HF: COMMON ALLOY DESIGNATION UNS N13010: COMMONLY LISTED IDENTIFICATION DESCRIPTION AMS 5406: ORIGINAL AMS SPECIFICATION AMS 5406A: REAFFIRMED IN 2001 AMS 5406B: CANCELLED APRIL 2007 PWA 1455: B-1900 + HF B-1900 + HF: NICKEL-BASE CAST SUPERALLOY UNS N13010: NICKEL-BASE ALLOY DESIGNATION SAE'S HISTORICAL RECORD IDENTIFIES AMS 5406A AND RECORDS THE SUBSEQUENT AMS 5406B REVISION; THE AVAILABLE AMS 5406B NOTICE STATES THAT IT WAS CANCELLED IN APRIL 2007 AFTER AEROSPACE USERS AND PRODUCERS INDICATED THAT THE PRODUCT WAS NOT BEING PRODUCED TO THE SPECIFICATION. AMS 5406 VS AMS 5406 ROUND BAR — AN IMPORTANT DISTINCTION THE PHRASE “AMS 5406 ROUND BAR” APPEARS IN COMMERCIAL AND ENGINEERING SEARCHES, BUT TECHNICALLY IT REQUIRES QUALIFICATION. AMS 5406 IS PRIMARILY A CASTING SPECIFICATION THE OFFICIAL SCOPE CONCERNS: • INVESTMENT CASTINGS • VACUUM MELTING • VACUUM CASTING • AS-CAST MATERIAL • NICKEL-BASED HEAT-RESISTANT ALLOY • CORROSION-RESISTANT AEROSPACE CASTINGS IT DOES NOT DEFINE A CONVENTIONAL WROUGHT ROUND-BAR PRODUCT FORM. THEREFORE, THE FOLLOWING TERMS SHOULD NOT AUTOMATICALLY BE TREATED AS IDENTICAL: • AMS 5406 ROUND BAR • AMS 5406 BAR • AMS 5406 ROD • B-1900 + HF ROUND BAR • PWA 1455 BAR • UNS N13010 ROUND BAR • B-1900 HF FORGED BAR A SUPPLIER SHOULD IDENTIFY THE ACTUAL MATERIAL STANDARD, MANUFACTURING ROUTE, PRODUCT FORM AND CERTIFICATION BASIS BEFORE REPRESENTING MATERIAL AS AMS 5406. AMS 5406 CHEMICAL COMPOSITION THE NOMINAL CHEMISTRY ASSOCIATED WITH AMS 5406 / B-1900 + HF IS A HIGH-ALLOY NICKEL-BASE SYSTEM CONTAINING CHROMIUM, COBALT, MOLYBDENUM, TITANIUM, TANTALUM, ALUMINUM, BORON, ZIRCONIUM AND HAFNIUM. A REPRESENTATIVE COMPOSITION REPORTED FOR THE ALLOY IS: NICKEL BALANCE CHROMIUM 8.0% COBALT 10.0% MOLYBDENUM 6.0% TITANIUM 1.0% TANTALUM 4.2–4.25% ALUMINUM 6.0% CARBON ~0.10% BORON 0.015% ZIRCONIUM ~0.03–0.10% HAFNIUM ~1.1–1.2% INDUSTRIAL ALLOY-SELECTION DATA IDENTIFIES B 1900 + HF WITH APPROXIMATELY 8% CR, 10% CO, 6% MO, 4.25% TA, 1% TI, 6% AL, 0.015% B, 0.1% ZR AND 1.1% HF. PUBLISHED TECHNICAL LITERATURE ALSO DESCRIBES B-1900 + HF AS APPROXIMATELY 7–9% CR, 9–11% CO, 5.5–6.5% MO, 0.75–1.25% TI, 3.8–4.7% TA, 5.5–6.5% AL, 1–1.3% HF, 0.1% C AND 0.015% B, WITH NICKEL AS THE BALANCE. ALWAYS USE THE APPLICABLE CONTROLLED MATERIAL SPECIFICATION AND HEAT-ANALYSIS CERTIFICATE FOR FINAL CHEMISTRY REQUIREMENTS. WHY HAFNIUM IS IMPORTANT IN B-1900 + HF THE DEFINING DIFFERENCE BETWEEN CONVENTIONAL B-1900 AND B-1900 + HF IS THE INTENTIONAL ADDITION OF HAFNIUM. THE ALLOY FAMILY IS COMMONLY PRESENTED AS: B-1900 → AMS 5405 B-1900 + HF → AMS 5406 / PWA 1455 THIS RELATIONSHIP IS DOCUMENTED IN VACUUM-MELT ALLOY REFERENCES. HAFNIUM IS IMPORTANT IN ADVANCED NICKEL-BASE CAST SUPERALLOYS BECAUSE ALLOYING ADDITIONS CAN INFLUENCE GRAIN-BOUNDARY CHARACTERISTICS, HIGH-TEMPERATURE STRENGTH AND ENVIRONMENTAL RESISTANCE. FOR AND PURCHASING PURPOSES, THIS CREATES SEVERAL IMPORTANT NAMES: • B-1900 HF • B-1900 + HF • B1900 HF • B1900+HF • B-1900 HAFNIUM • B-1900 WITH HAFNIUM • B-1900 HF SUPERALLOY • B-1900 NICKEL SUPERALLOY • PWA 1455 • AMS 5406 • AMS5406 • AMS 5406B • UNS N13010 INTERNATIONAL EQUIVALENTS AND CROSS-REFERENCES THERE IS NO UNIVERSAL RULE THAT ALLOWS EVERY NATIONAL MATERIAL STANDARD TO BE SUBSTITUTED DIRECTLY FOR AMS 5406) FOR AEROSPACE PROCUREMENT, AN “EQUIVALENT” MUST BE VERIFIED AGAINST THE ACTUAL SPECIFICATION, CHEMISTRY, PRODUCT FORM, HEAT TREATMENT AND CUSTOMER DRAWING.

THEY ARE DIFFERENT ALLOY SYSTEMS WITH DIFFERENT CHEMISTRY, MICROSTRUCTURE, PRODUCT FORMS AND SPECIFICATIONS. COMMON NAMES AND TRADE NAMES THE MOST RELEVANT COMMON NAMES AND SEARCH TERMS INCLUDE: PRIMARY NAMES • AMS 5406 • AMS5406 • SAE AMS 5406 • AMS 5406B • B-1900 + HF • B-1900 HF • B1900 HF • B1900+HF • B-1900 HAFNIUM • B-1900 WITH HAFNIUM • PWA 1455 • UNS N13010 COMMERCIAL SEARCH PHRASES • AMS 5406 ROUND BAR • AMS 5406 BAR • AMS 5406 ROD • AMS 5406 NICKEL ALLOY • AMS 5406 MATERIAL • AMS 5406 SUPPLIER • AMS 5406 MANUFACTURER • AMS 5406 STOCKIST • AMS 5406 EXPORTER • B-1900 HF ROUND BAR • B-1900 HF BAR • B-1900 HF ROD • B-1900 HF MATERIAL • B-1900 HF ALLOY • PWA 1455 MATERIAL • PWA 1455 ALLOY • NICKEL SUPERALLOY ROUND BAR • NICKEL BASED SUPERALLOY • HIGH TEMPERATURE NICKEL ALLOY • AEROSPACE NICKEL ALLOY BRAND NAMES: WHAT SHOULD BE USED CAREFULLY? UNLIKE COMMERCIALLY BRANDED ALLOYS SUCH AS INCONEL, HASTELLOY OR WASPALOY, B-1900 + HF IS PRIMARILY ENCOUNTERED UNDER ALLOY/SPECIFICATION DESIGNATIONS SUCH AS B-1900 + HF, PWA 1455 AND AMS 5406. IT WOULD THEREFORE BE MISLEADING TO DESCRIBE AMS 5406 AS AN INCONEL ALLOY. INCONEL IS A FAMILY OF REGISTERED NICKEL-ALLOY TRADE NAMES ASSOCIATED WITH SPECIFIC COMPOSITIONS AND SPECIFICATIONS. AMS 5406/B-1900 + HF SHOULD BE IDENTIFIED BY ITS ACTUAL DESIGNATION RATHER THAN BEING MARKETED AS AN INCONEL GRADE. AMS 5406 MANUFACTURING PROCESS BECAUSE AMS 5406 IS A CASTING SPECIFICATION, ITS MANUFACTURING ROUTE IS FUNDAMENTALLY DIFFERENT FROM CONVENTIONAL STAINLESS-STEEL OR NICKEL-ALLOY ROUND-BAR PRODUCTION. 1) RAW MATERIAL SELECTION THE CHARGE MATERIALS MUST BE CAREFULLY SELECTED TO CONTROL: • NICKEL • CHROMIUM • COBALT • MOLYBDENUM • ALUMINUM • TITANIUM • TANTALUM • HAFNIUM • BORON • ZIRCONIUM • CARBON • RESIDUAL ELEMENTS HIGH-PURITY CHARGE CONTROL IS PARTICULARLY IMPORTANT FOR AEROSPACE SUPERALLOYS. 2) VACUUM MELTING AMS 5406 SPECIFIES A VACUUM-MELTED MATERIAL. VACUUM MELTING HELPS CONTROL: • ATMOSPHERIC CONTAMINATION • OXYGEN • NITROGEN • HYDROGEN • VOLATILE ELEMENTS • UNDESIRABLE INCLUSIONS INDUSTRIAL VACUUM-MELT REFERENCES CLASSIFY B-1900 + HF AMONG NICKEL-BASE EQUIAXED SUPERALLOYS USED FOR INVESTMENT CASTING. 3) CHEMICAL ANALYSIS AFTER MELTING, THE HEAT IS ANALYZED TO CONFIRM THE REQUIRED CHEMISTRY. TYPICAL ANALYTICAL CONTROLS INCLUDE: • OPTICAL EMISSION SPECTROSCOPY • X-RAY FLUORESCENCE WHERE APPROPRIATE • COMBUSTION ANALYSIS FOR CARBON • INERT-GAS FUSION FOR OXYGEN/NITROGEN/HYDROGEN • LABORATORY VERIFICATION OF CRITICAL ALLOYING ELEMENTS FOR AEROSPACE PRODUCTION, CHEMICAL TRACEABILITY SHOULD EXTEND FROM THE MELT HEAT THROUGH CASTING AND FINAL INSPECTION. 4) INVESTMENT PATTERN MANUFACTURING THE INVESTMENT CASTING PROCESS GENERALLY BEGINS WITH A PRECISION WAX OR POLYMER PATTERN. THE PATTERN IS: 1. MANUFACTURED TO DIMENSIONAL REQUIREMENTS 2. ATTACHED TO A GATING SYSTEM 3. COATED WITH CERAMIC SLURRY 4. STUCCOED WITH REFRACTORY MATERIAL 5. DRIED 6. REPEATEDLY BUILT INTO A CERAMIC SHELL 7. DEWAXED 8. FIRED/PREHEATED 9. FILLED WITH MOLTEN ALLOY THIS PROCESS ENABLES COMPLEX TURBINE AND COMBUSTION-COMPONENT GEOMETRIES THAT WOULD BE DIFFICULT TO MANUFACTURE ECONOMICALLY FROM CONVENTIONAL BAR STOCK. 5) VACUUM INVESTMENT CASTING THE PREPARED CERAMIC MOLD IS FILLED WITH VACUUM-MELTED B-1900 + HF ALLOY. VACUUM CASTING IS ESPECIALLY IMPORTANT FOR AEROSPACE NICKEL-BASE SUPERALLOYS BECAUSE INTERNAL DEFECTS, INCLUSIONS AND GAS-RELATED POROSITY CAN COMPROMISE FATIGUE AND HIGH-TEMPERATURE PERFORMANCE. THE SPECIFICATION ITSELF IDENTIFIES THE MATERIAL AS VACUUM MELTED, VACUUM CAST AND AS CAST. 6) SOLIDIFICATION AND MICROSTRUCTURE CONTROL THE COOLING STAGE DETERMINES THE RESULTING CAST MICROSTRUCTURE. IMPORTANT METALLURGICAL CONSIDERATIONS INCLUDE: • GRAIN SIZE • DENDRITIC STRUCTURE • SEGREGATION • CARBIDES • GAMMA/GAMMA-PRIME PHASES • GRAIN-BOUNDARY CONSTITUENTS • MICROPOROSITY • HOT TEARING • SHRINKAGE • CASTING INCLUSIONS FOR TURBINE APPLICATIONS, CONTROLLING SOLIDIFICATION AND SUBSEQUENT INSPECTION IS CRITICAL TO ACHIEVING CONSISTENT PERFORMANCE. 7) HEAT TREATMENT THE EXACT HEAT-TREATMENT CYCLE MUST BE ESTABLISHED FROM THE CONTROLLING SPECIFICATION, DRAWING OR APPROVED PROCESS SPECIFICATION. NICKEL-BASE SUPERALLOYS CAN USE CAREFULLY CONTROLLED THERMAL CYCLES TO MODIFY: • GAMMA-PRIME PRECIPITATION • CARBIDE MORPHOLOGY • RESIDUAL STRESS • SEGREGATION EFFECTS • GRAIN-BOUNDARY STRUCTURE • MECHANICAL PROPERTIES DO NOT COPY A GENERIC B-1900 HEAT-TREATMENT CYCLE ONTO AN AMS 5406 PURCHASE ORDER WITHOUT CHECKING THE CONTROLLING SPECIFICATION. 8) HIP PROCESSING HOT ISOSTATIC PRESSING, OR HIP, MAY BE USED FOR SUITABLE CAST SUPERALLOY COMPONENTS WHERE PERMITTED BY THE APPLICABLE ENGINEERING SPECIFICATION. HIP CAN REDUCE INTERNAL CASTING POROSITY AND IMPROVE STRUCTURAL INTEGRITY. HISTORICAL RESEARCH ON B-1900 + HF INCLUDES WORK INVOLVING CAST MATERIAL AND HIP-RELATED PROCESSING, DEMONSTRATING THE IMPORTANCE OF INTERNAL CASTING QUALITY IN THIS ALLOY FAMILY. HOWEVER, HIP SHOULD ONLY BE CLAIMED AS SPECIFICATION-COMPLIANT WHEN THE RELEVANT CUSTOMER OR MATERIAL SPECIFICATION PERMITS IT. 9) MACHINING AMS 5406 / B-1900 + HF NICKEL-BASE PRECIPITATION-STRENGTHENED SUPERALLOYS ARE GENERALLY DIFFICULT TO MACHINE BECAUSE OF: • HIGH STRENGTH • WORK HARDENING • LOW THERMAL CONDUCTIVITY • HIGH CUTTING TEMPERATURES • ABRASIVE/INTERMETALLIC CONSTITUENTS • TOOL-EDGE WEAR RECOMMENDED MANUFACTURING CONTROLS INCLUDE: • RIGID MACHINE SETUP • SHARP CUTTING TOOLS • CONTROLLED CUTTING SPEEDS • APPROPRIATE FEEDS • HIGH-PRESSURE COOLANT WHERE SUITABLE • AVOIDING EXCESSIVE DWELL • MINIMIZING WORK HARDENING • CONTINUOUS CHIP CONTROL WHEN MACHINING A CASTING, THE MACHINING PROCESS MUST ALSO ACCOUNT FOR LOCAL MICROSTRUCTURAL VARIATIONS AND POSSIBLE CASTING DEFECTS. AMS 5406 ROUND BAR MANUFACTURING — IF A CUSTOMER REQUESTS BAR IF THE CUSTOMER SPECIFICALLY REQUESTS A B-1900 + HF ROUND BAR, THE MANUFACTURER SHOULD FIRST DETERMINE WHETHER THE CUSTOMER NEEDS: OPTION A — AMS 5406 CASTING MANUFACTURE THE COMPONENT AS A VACUUM-MELTED INVESTMENT CASTING ACCORDING TO THE APPLICABLE HISTORICAL/CURRENT CONTRACTUAL SPECIFICATION. OPTION B — B-1900 + HF MATERIAL IN BAR FORM MANUFACTURE OR SUPPLY A BAR USING AN APPLICABLE SPECIFICATION GOVERNING THAT PRODUCT FORM. OPTION C — MATERIAL FOR LABORATORY TESTING A BAR OR COUPON MAY BE PRODUCED FOR MECHANICAL TESTING OR RESEARCH PURPOSES, BUT IT SHOULD NOT AUTOMATICALLY BE REPRESENTED AS AN AMS 5406-CERTIFIED ROUND BAR. THIS DISTINCTION IS EXTREMELY IMPORTANT FOR AEROSPACE PROCUREMENT. TYPICAL APPLICATIONS B-1900 + HF / PWA 1455 HAS BEEN ASSOCIATED WITH HIGH-TEMPERATURE GAS-TURBINE AND AEROSPACE APPLICATIONS. REPORTED APPLICATIONS INCLUDE: • GAS TURBINE COMPONENTS • TURBINE BLADES • TURBINE VANES • COMBUSTOR COMPONENTS • COMBUSTOR LINER PANELS • HIGH-TEMPERATURE STRUCTURAL COMPONENTS • AEROSPACE HOT-SECTION COMPONENTS NASA RESEARCH SPECIFICALLY IDENTIFIES CAST PWA 1455 (B-1900 + HF) IN STUDIES OF TURBINE HOT-SECTION MATERIALS. PATENT LITERATURE ALSO IDENTIFIES B-1900 + HF / AMS 5406 IN HIGH-TEMPERATURE COMBUSTOR LINER APPLICATIONS. HIGH-TEMPERATURE PERFORMANCE B-1900 + HF BELONGS TO THE CLASS OF NICKEL-BASE SUPERALLOYS DEVELOPED FOR HIGH-TEMPERATURE SERVICE. ITS ALLOYING SYSTEM COMBINES: • NICKEL FOR THE MATRIX • CHROMIUM FOR OXIDATION/CORROSION RESISTANCE • COBALT FOR HIGH-TEMPERATURE PHASE STABILITY • MOLYBDENUM FOR SOLID-SOLUTION STRENGTHENING • ALUMINUM AND TITANIUM FOR PRECIPITATION STRENGTHENING • TANTALUM FOR STRENGTHENING • HAFNIUM FOR MICROSTRUCTURAL/GRAIN-BOUNDARY EFFECTS • BORON AND ZIRCONIUM FOR GRAIN-BOUNDARY CONTROL HISTORICAL TECHNICAL REFERENCES DESCRIBE B-1900 + HF AS USEFUL AT TEMPERATURES APPROACHING APPROXIMATELY 1, 400°F / 760°C IN CERTAIN TURBINE APPLICATIONS. ACTUAL ALLOWABLE OPERATING TEMPERATURE DEPENDS ON COMPONENT DESIGN, STRESS, ENVIRONMENT, COATING, MICROSTRUCTURE AND THE CONTROLLING ENGINEERING SPECIFICATION. AMS 5406 INSPECTION AND QUALITY CONTROL AEROSPACE CASTING QUALITY REQUIRES MORE THAN CHEMICAL ANALYSIS. TYPICAL INSPECTION PROGRAMS MAY INCLUDE: CHEMICAL INSPECTION • HEAT ANALYSIS • PRODUCT ANALYSIS WHERE REQUIRED • RESIDUAL-ELEMENT ANALYSIS DIMENSIONAL INSPECTION • DIAMETER • LENGTH • PROFILE • MACHINED DIMENSIONS • DRAWING TOLERANCES VISUAL INSPECTION • SURFACE CRACKS • COLD SHUTS • MISRUNS • FLASH • SURFACE DISCONTINUITIES NON-DESTRUCTIVE TESTING DEPENDING ON THE DRAWING AND APPLICABLE SPECIFICATION: • RADIOGRAPHIC TESTING • FLUORESCENT PENETRANT INSPECTION • ULTRASONIC TESTING • MAGNETIC-PARTICLE INSPECTION WHERE TECHNICALLY APPROPRIATE • COMPUTED TOMOGRAPHY FOR ADVANCED INTERNAL INSPECTION METALLOGRAPHIC INSPECTION MAY INCLUDE: • GRAIN STRUCTURE • POROSITY • CARBIDES • MICROSTRUCTURAL CONSTITUENTS • HEAT-TREATMENT RESPONSE RECOMMENDED AEROSPACE DOCUMENTATION A PROFESSIONAL AEROSPACE MATERIAL SUPPLY PACKAGE CAN INCLUDE: • MATERIAL TEST CERTIFICATE • CERTIFICATE OF CONFORMANCE • HEAT NUMBER • MELT NUMBER • CHEMICAL ANALYSIS • PRODUCT FORM • MANUFACTURING ROUTE • HEAT-TREATMENT RECORD • NDT REPORTS • DIMENSIONAL INSPECTION REPORT • TRACEABILITY DOCUMENTATION • COUNTRY OF ORIGIN WHERE REQUIRED • CUSTOMER-SPECIFIC DOCUMENTATION • EN 10204-STYLE CERTIFICATION WHERE CONTRACTUALLY APPLICABLE FOR OBSOLETE OR CANCELLED SPECIFICATIONS, THE PURCHASE ORDER SHOULD CLEARLY STATE THE CONTRACTUAL BASIS UNDER WHICH HISTORICAL MATERIAL IS BEING SUPPLIED.

NO. SAE'S STATED SCOPE IS FOR VACUUM-MELTED, VACUUM-CAST INVESTMENT CASTINGS, NOT CONVENTIONAL WROUGHT ROUND BAR. WHAT ALLOY IS AMS 5406? AMS 5406 IS ASSOCIATED WITH B-1900 + HF, A NICKEL-BASE HEAT-RESISTANT SUPERALLOY. WHAT IS THE PWA EQUIVALENT OF AMS 5406? THE COMMONLY ASSOCIATED PRATT & WHITNEY DESIGNATION IS PWA 1455) NASA DOCUMENTATION IDENTIFIES CAST PWA 1455 AS B-1900 + HF. WHAT IS B-1900 + HF? B-1900 + HF IS A HAFNIUM-CONTAINING NICKEL-BASE SUPERALLOY ASSOCIATED WITH AMS 5406 AND PWA 1455. IS AMS 5406 STILL ACTIVE? THE HISTORICAL AMS 5406 SPECIFICATION FAMILY IS NOT A CURRENT NEW-DESIGN MATERIAL SPECIFICATION. AMS 5406B WAS CANCELLED IN APRIL 2007, WITH THE CANCELLATION NOTICE STATING THAT THE PRODUCT WAS NOT BEING PRODUCED TO THE SPECIFICATION. IS AMS 5406 THE SAME AS AMS 5405? NO. AMS 5405 IS ASSOCIATED WITH B-1900, WHILE AMS 5406 IS ASSOCIATED WITH B-1900 + HF. IS AMS 5406 THE SAME AS INCONEL? NO. AMS 5406/B-1900 + HF IS A DISTINCT NICKEL-BASE SUPERALLOY AND SHOULD NOT BE MARKETED AS AN INCONEL GRADE. CAN B-1900 + HF BE SUPPLIED AS ROUND BAR? MATERIAL IN BAR FORM MAY EXIST FOR RESEARCH, MACHINING OR OTHER CONTRACTUAL PURPOSES, BUT BAR FORM SHOULD NOT AUTOMATICALLY BE REPRESENTED AS AMS 5406-COMPLIANT. THE APPLICABLE BAR SPECIFICATION AND CERTIFICATION BASIS MUST BE ESTABLISHED. WHAT INDUSTRIES USE B-1900 + HF? THE ALLOY IS ASSOCIATED WITH AEROSPACE AND GAS-TURBINE HOT-SECTION APPLICATIONS, INCLUDING TURBINE AND COMBUSTOR COMPONENTS. HOW TO SPECIFY AMS 5406 MATERIAL CORRECTLY FOR AN AEROSPACE INQUIRY, PROVIDE: MATERIAL: B-1900 + HF / AMS 5406 SPECIFICATION: APPLICABLE AMS REVISION OR CONTRACTUAL REQUIREMENT PRODUCT FORM: INVESTMENT CASTING / OTHER SPECIFICALLY APPROVED FORM CONDITION: AS CAST OR CUSTOMER-SPECIFIED CONDITION QUANTITY: REQUIRED PIECES/WEIGHT DIMENSIONS: FINISHED AND/OR CASTING DIMENSIONS HEAT NUMBER: REQUIRED INSPECTION: CUSTOMER DRAWING AND APPLICABLE NDT REQUIREMENTS CERTIFICATION: MTC + COC + TRACEABILITY APPLICATION: AEROSPACE / GAS TURBINE / HIGH-TEMPERATURE SERVICE FOR A ROUND-BAR INQUIRY, REPLACE THE SPECIFICATION WITH THE ACTUAL BAR/WROUGHT-MATERIAL SPECIFICATION RATHER THAN ASSUMING AMS 5406 APPLIES. CONCLUSION AMS 5406 IS BEST UNDERSTOOD AS A HISTORICAL SAE AEROSPACE SPECIFICATION FOR VACUUM-MELTED, VACUUM-CAST INVESTMENT CASTINGS OF THE B-1900 + HF NICKEL-BASE SUPERALLOY. IT IS ASSOCIATED WITH B-1900 + HF, PWA 1455 AND COMMONLY REFERENCED AS UNS N13010, ALTHOUGH EQUIVALENT-GRADE CLAIMS MUST ALWAYS BE VERIFIED AGAINST THE APPLICABLE PROCUREMENT SPECIFICATION. FOR PURPOSES, TERMS SUCH AS AMS 5406 ROUND BAR, AMS5406 MATERIAL, AMS 5406 ALLOY, B-1900 HF, B-1900 + HF, PWA 1455, NICKEL-BASED SUPERALLOY, AEROSPACE NICKEL ALLOY, HIGH-TEMPERATURE NICKEL ALLOY, INVESTMENT CASTING AND VACUUM CAST NICKEL ALLOY CAN CAPTURE VALUABLE INTERNATIONAL SEARCH INTENT. FOR TECHNICAL ACCURACY, HOWEVER, MANUFACTURERS AND EXPORTERS SHOULD CLEARLY DISTINGUISH AMS 5406 INVESTMENT CASTINGS FROM ROUND BAR PRODUCTS. THIS DISTINCTION IS PARTICULARLY IMPORTANT BECAUSE THE AMS 5406B DOCUMENT WAS CANCELLED IN 2007.
