AMS 5396 ROUND BAR MANUFACTURING: GLOBAL GUIDE TO HASTELLOY B / N-12MV NICKEL ALLOY, UNS N10001 EQUIVALENTS, STANDARDS, APPLICATIONS & PRECISION MACHINING IMPORTANT SPECIFICATION NOTE: SAE AMS 5396 IS NOT A ROUND-BAR SPECIFICATION. THE CURRENT SPECIFICATION, AMS 5396G, COVERS CORROSION- AND HEAT-RESISTANT NICKEL-ALLOY INVESTMENT CASTINGS IN THE AS-CAST CONDITION, IDENTIFIED WITH THE CHEMISTRY 65NI–28MO–5.5FE–0.40V, AND REFERENCES N-12MV / HASTELLOY B. THEREFORE, MARKETING A PRODUCT SIMPLY AS AN “AMS 5396 ROUND BAR” CAN BE TECHNICALLY MISLEADING. FOR AND PROCUREMENT PURPOSES, HOWEVER, SEARCHES SUCH AS AMS 5396 ROUND BAR, AMS 5396 BAR, AMS5396 NICKEL ALLOY, HASTELLOY B ROUND BAR, N10001 ROUND BAR, N-12MV ALLOY, HASTELLOY B MATERIAL, NICKEL MOLYBDENUM ALLOY BAR AND AMS 5396 EQUIVALENT ARE HIGHLY RELEVANT SEARCH-INTENT TERMS. THIS GUIDE EXPLAINS THE DISTINCTION AND SHOWS HOW AMS 5396 MATERIAL CAN BE ADDRESSED CORRECTLY WHEN A CUSTOMER REQUESTS BAR, BILLET, MACHINED COMPONENTS, OR INVESTMENT CASTINGS. AMS 5396 MATERIAL AT A GLANCE AMS 5396 IS AN SAE AEROSPACE MATERIAL SPECIFICATION FOR AN INVESTMENT-CAST NICKEL-BASE ALLOY DESIGNED FOR CORROSION AND HEAT RESISTANCE. THE CURRENT REVISION IS AMS 5396G, REVISED AUGUST 22, 2025) THE MATERIAL IS ASSOCIATED WITH: • HASTELLOY B • N-12MV • UNS N10001 IN WROUGHT-MATERIAL IDENTIFICATION • NICKEL-MOLYBDENUM ALLOY • NI-MO CORROSION-RESISTANT ALLOY • HASTELLOY B ALLOY • ALLOY B • AMS 5396 • ASTM A494 N12MV FOR THE COMPARABLE CAST-GRADE DESIGNATION INDUSTRY MATERIAL REFERENCES IDENTIFY AMS 5396 WITH HASTELLOY B / UNS N10001, WHILE ASTM A494 N12MV IS A CAST-GRADE DESIGNATION WITH CLOSELY RELATED CHEMISTRY. KEY IDENTIFICATION TABLE ITEM IDENTIFICATION SAE SPECIFICATION: AMS 5396 / AMS 5396G MATERIAL FAMILY: NICKEL-BASE CORROSION- AND HEAT-RESISTANT ALLOY PRODUCT FORM UNDER AMS 5396: INVESTMENT CASTING CONDITION: AS CAST COMMERCIAL NAME: HASTELLOY B CAST DESIGNATION: N-12MV / ASTM A494 N12MV UNS ASSOCIATED WITH HASTELLOY B: UNS N10001 PRINCIPAL ALLOYING ELEMENT: MOLYBDENUM NOMINAL CHEMISTRY: 65NI–28MO–5.5FE–0.40V MAJOR APPLICATION CHARACTERISTIC: STRONG RESISTANCE TO REDUCING ACIDS, ESPECIALLY HYDROCHLORIC-ACID ENVIRONMENTS SAE'S CURRENT LISTING EXPLICITLY IDENTIFIES AMS 5396G AS AN INVESTMENT-CASTING SPECIFICATION AND GIVES THE 65NI–28MO–5.5FE–0.40V COMPOSITION DESIGNATION. WHAT IS AMS 5396? AMS 5396 ORIGINATED IN 1960 AS A SPECIFICATION FOR NICKEL-BASE CORROSION- AND HEAT-RESISTANT INVESTMENT CASTINGS. THE SPECIFICATION HAS SUBSEQUENTLY PASSED THROUGH REVISIONS INCLUDING AMS 5396A, B, C, D, E, F AND THE CURRENT G REVISION. THE ORIGINAL SPECIFICATION WAS TITLED “ALLOY CASTINGS, INVESTMENT, CORROSION AND HEAT RESISTANT NICKEL BASE – 28MO – 5FE – 0.4V.” LATER REVISIONS MORE SPECIFICALLY IDENTIFY THE ALLOY AS APPROXIMATELY 65% NICKEL, 28% MOLYBDENUM, 5.5% IRON AND 0.40% VANADIUM. THIS IS PARTICULARLY IMPORTANT FOR PURCHASING DEPARTMENTS BECAUSE AMS 5396 SHOULD NOT AUTOMATICALLY BE TREATED AS EQUIVALENT TO A WROUGHT ROUND-BAR SPECIFICATION. AMS 5396 ROUND BAR: THE CORRECT TECHNICAL INTERPRETATION A CUSTOMER SEARCHING FOR: • AMS 5396 ROUND BAR • AMS5396 BAR • AMS 5396 NICKEL BAR • AMS 5396 ROD • AMS 5396 SHAFT • AMS 5396 ALLOY BAR • AMS 5396 MATERIAL • AMS 5396 STOCK • AMS 5396 HASTELLOY B MAY ACTUALLY BE LOOKING FOR A HASTELLOY B / N10001 NICKEL-MOLYBDENUM MATERIAL IN BAR FORM, RATHER THAN AN INVESTMENT CASTING CERTIFIED SPECIFICALLY TO AMS 5396. THAT DISTINCTION MATTERS. AMS 5396 SPECIFIES: INVESTMENT CASTINGS → AS-CAST PRODUCT A ROUND BAR NORMALLY INVOLVES: WROUGHT MATERIAL → BILLET → HOT WORKING/FORGING/ROLLING → HEAT TREATMENT → STRAIGHTENING → MACHINING/CENTERLESS GRINDING → TESTING CONSEQUENTLY, IF A CUSTOMER REQUIRES AN ACTUAL ROUND BAR, THE MANUFACTURER SHOULD ESTABLISH THE REQUIRED WROUGHT MATERIAL SPECIFICATION, RATHER THAN SIMPLY TRANSFERRING THE AMS 5396 CASTING DESIGNATION TO A BAR. A MATERIALS DATABASE IDENTIFIES THE CAST MATERIAL AS N-12MV / UNS N30012 WHILE DISTINGUISHING IT FROM WROUGHT UNS N10665 HASTELLOY B-2 AND ALSO ASSOCIATES AMS 5396 WITH HASTELLOY B. AMS 5396 CHEMICAL COMPOSITION THE AMS 5396 ALLOY IS A HIGH-MOLYBDENUM NICKEL-BASE MATERIAL. ITS PRINCIPAL NOMINAL CHEMISTRY IS REPRESENTED AS: NICKEL – APPROXIMATELY 65% MOLYBDENUM – APPROXIMATELY 28% IRON – APPROXIMATELY 5.5% VANADIUM – APPROXIMATELY 0.40% INDUSTRY ALLOY TABLES FOR HASTELLOY B UNDER AMS 5396 SHOW NICKEL AS THE BALANCE, MOLYBDENUM AROUND 26–30%, IRON APPROXIMATELY 4–7%, VANADIUM APPROXIMATELY 0.20–0.60%, WITH CARBON, MANGANESE, SILICON, PHOSPHORUS AND SULFUR CONTROLLED WITHIN SPECIFIED LIMITS. ALWAYS USE THE PURCHASED REVISION OF AMS 5396 FOR CONTRACTUAL CHEMICAL LIMITS. A WEBSITE TABLE SHOULD NOT REPLACE THE CONTROLLED SAE SPECIFICATION. AMS 5396 VS HASTELLOY B THE TERMS ARE CLOSELY ASSOCIATED BUT SHOULD NOT BE USED CARELESSLY. HASTELLOY B IS THE COMMERCIAL/TRADE DESIGNATION HISTORICALLY ASSOCIATED WITH THE ALLOY. UNS N10001 IS THE UNIFIED NUMBERING SYSTEM DESIGNATION ASSOCIATED WITH HASTELLOY B. AMS 5396 IS AN SAE SPECIFICATION GOVERNING A PARTICULAR INVESTMENT-CASTING PRODUCT FORM. ASTM A494 N12MV IS A CAST NICKEL-ALLOY DESIGNATION COMMONLY CROSS-REFERENCED WITH THIS MATERIAL FAMILY. AN INDUSTRY CROSS-REFERENCE LISTS: HASTELLOY B → AMS 5396 → UNS N10001, WHILE OTHER CASTING REFERENCES IDENTIFY N12MV UNDER ASTM A494) AMS 5396 INTERNATIONAL EQUIVALENTS AND CROSS-REFERENCES THERE IS NO UNIVERSAL ONE-TO-ONE INTERNATIONAL EQUIVALENT THAT SHOULD AUTOMATICALLY REPLACE AMS 5396. A RESPONSIBLE CROSS-REFERENCE SHOULD DISTINGUISH BETWEEN EXACT SPECIFICATION EQUIVALENCE, SAME ALLOY FAMILY, SIMILAR CHEMISTRY, AND DIFFERENT PRODUCT FORM.

SIMILAR TRADE NAMES AND COMMON NAMES FOR INTERNATIONAL PURCHASING AND COVERAGE, AMS 5396 CAN APPEAR UNDER NUMEROUS NAMES. COMMON NAMES • AMS 5396 • AMS5396 • AMS 5396G • ALLOY 5396 • NICKEL ALLOY AMS 5396 • NICKEL BASE ALLOY • NICKEL MOLYBDENUM ALLOY • NI-MO ALLOY • CORROSION RESISTANT NICKEL ALLOY • HEAT RESISTANT NICKEL ALLOY • INVESTMENT CASTING ALLOY • NICKEL ALLOY CASTING TRADE / COMMERCIAL NAMES • HASTELLOY B • ALLOY B • HASTELLOY B ALLOY • N-12MV • N12MV MATERIAL IDENTIFICATION TERMS • UNS N10001 • N10001 • NIMO ALLOY • NIMO30 • WERKSTOFF 2.4810 SOME REFERENCES ALSO ASSOCIATE ASTM A494 N12MV WITH THE N-12MV CAST GRADE. BRAND NAMES AND TRADEMARK CONSIDERATIONS HASTELLOY IS A WELL-KNOWN COMMERCIAL/TRADE NAME ASSOCIATED WITH NICKEL-BASED CORROSION-RESISTANT ALLOYS. FOR A MANUFACTURER'S WEBSITE, IT IS PREFERABLE TO WRITE: “HASTELLOY B / AMS 5396 NICKEL ALLOY” RATHER THAN PRESENTING HASTELLOY AS THOUGH IT WERE ITSELF AN SAE SPECIFICATION. LIKEWISE, AMS 5396, ASTM A494, AND UNS DESIGNATIONS DESCRIBE SPECIFICATIONS OR MATERIAL-IDENTIFICATION SYSTEMS; THEY ARE NOT INTERCHANGEABLE WITH COMMERCIAL TRADEMARKS. AMS 5396 MANUFACTURING PROCESS BECAUSE AMS 5396 IS AN INVESTMENT-CASTING SPECIFICATION, ITS MANUFACTURING ROUTE DIFFERS FUNDAMENTALLY FROM CONVENTIONAL ROUND-BAR PRODUCTION. 1) RAW MATERIAL SELECTION THE FOUNDRY BEGINS WITH CONTROLLED NICKEL-BASE CHARGE MATERIALS. TYPICAL CHARGE PLANNING CONSIDERS: • NICKEL • MOLYBDENUM • IRON • VANADIUM • CARBON • SILICON • MANGANESE • PHOSPHORUS • SULFUR TRACE-ELEMENT CONTROL IS IMPORTANT BECAUSE THE ALLOY'S CORROSION PERFORMANCE DEPENDS STRONGLY ON ITS CHEMICAL BALANCE. 2) MELTING NICKEL-MOLYBDENUM ALLOYS REQUIRE CONTROLLED MELTING PRACTICES. DEPENDING ON THE FOUNDRY AND COMPONENT REQUIREMENTS, PRODUCTION MAY INVOLVE: • VACUUM MELTING • CONTROLLED-ATMOSPHERE MELTING • INDUCTION MELTING • REMELTING • MASTER-HEAT CONTROL HISTORICAL AMS 5396 INFORMATION DESCRIBES INVESTMENT CASTINGS BEING POURED FROM A REMELTED MASTER HEAT OR DIRECTLY FROM A MASTER HEAT, WITH HISTORICAL MASTER-HEAT WEIGHT CONTROLS. 3) INVESTMENT PATTERN PRODUCTION THE DESIRED COMPONENT GEOMETRY IS REPRODUCED THROUGH AN INVESTMENT-CASTING PATTERN. TYPICAL SEQUENCE: PATTERN → TREE ASSEMBLY → CERAMIC SHELL → DEWAXING → PREHEATING → ALLOY POURING → SOLIDIFICATION → SHELL REMOVAL → CUTOFF → FINISHING THIS PROCESS IS PARTICULARLY VALUABLE FOR INTRICATE NICKEL-ALLOY COMPONENTS WHERE MACHINING AN ENTIRE COMPONENT FROM BAR WOULD CREATE EXCESSIVE MATERIAL WASTE. CAN AMS 5396 BE MANUFACTURED AS ROUND BAR? THIS IS ONE OF THE MOST IMPORTANT TECHNICAL QUESTIONS. SHORT ANSWER: NOT UNDER AMS 5396 ALONE. AMS 5396 IS EXPLICITLY AN INVESTMENT-CASTING SPECIFICATION, NOT A GENERAL WROUGHT-ROUND-BAR SPECIFICATION. A SUPPLIER RECEIVING AN INQUIRY FOR: “AMS 5396 ROUND BAR” SHOULD CLARIFY WHETHER THE CUSTOMER REQUIRES: 1. AMS 5396-CERTIFIED INVESTMENT CASTINGS; 2. HASTELLOY B / UNS N10001 MATERIAL; 3. N-12MV CAST MATERIAL; 4. A WROUGHT HASTELLOY B ROUND BAR; 5. A MACHINED BAR/COMPONENT; 6. A CAST BILLET SUBSEQUENTLY MACHINED INTO A CYLINDRICAL COMPONENT. THESE ARE TECHNICALLY DIFFERENT PURCHASING REQUIREMENTS. ASTM A494 N12MV AND AMS 5396 ASTM A494 IS AN IMPORTANT STANDARD IN THE NICKEL- AND NICKEL-ALLOY CASTING SECTOR. MATERIAL-SELECTION REFERENCES LIST HASTELLOY B / AMS 5396 ALONGSIDE ASTM A494 N12MV, WITH CLOSELY RELATED NICKEL-MOLYBDENUM CHEMISTRY. HOWEVER: AMS 5396 ≠ ASTM A494 N12MV IN EVERY CONTRACTUAL RESPECT. A SPECIFICATION COMPARISON MUST CONSIDER: • CHEMISTRY • CASTING PROCESS • HEAT TREATMENT • MECHANICAL PROPERTIES • TESTING • INSPECTION • DIMENSIONAL REQUIREMENTS • ACCEPTANCE CRITERIA • CERTIFICATION REQUIREMENTS • PRODUCT FORM THEREFORE, AN ASTM A494 N12MV CASTING SHOULD NOT AUTOMATICALLY BE CERTIFIED AS AMS 5396 UNLESS IT SATISFIES ALL APPLICABLE REQUIREMENTS OF THE REQUESTED AMS REVISION. MECHANICAL PROPERTIES HISTORICAL TECHNICAL DATA FOR AMS 5396/HASTELLOY B INVESTMENT CASTINGS REPORTS MINIMUM ROOM-TEMPERATURE PROPERTIES AROUND: • TENSILE STRENGTH: 75 KSI • 0.2% YIELD STRENGTH: 50 KSI • ELONGATION: APPROXIMATELY 10–12% • HARDNESS: APPROXIMATELY 180–235 BHN IN HISTORICAL DATA NASA ARCHIVAL MATERIAL DISCUSSING AMS-5396 REPORTS 75, 000 PSI TENSILE STRENGTH, 50, 000 PSI YIELD STRENGTH AND 10% ELONGATION AT ROOM TEMPERATURE, WITH ELEVATED-TEMPERATURE TENSILE REQUIREMENTS ALSO REPORTED. OTHER FOUNDRY DATA SUMMARIZE ALLOY B / AMS 5396 AT APPROXIMATELY 75 KSI TENSILE STRENGTH, 50 KSI YIELD STRENGTH AND 12% ELONGATION. THESE FIGURES SHOULD BE TREATED AS REFERENCE VALUES, NOT SUBSTITUTES FOR THE CURRENT AMS 5396G ACCEPTANCE REQUIREMENTS. CORROSION RESISTANCE OF AMS 5396 ONE OF THE MAJOR REASONS FOR SELECTING THIS ALLOY FAMILY IS ITS STRONG RESISTANCE TO REDUCING ENVIRONMENTS. THE HIGH MOLYBDENUM CONTENT PROVIDES IMPORTANT RESISTANCE TO: • HYDROCHLORIC ACID • REDUCING ACID ENVIRONMENTS • CHEMICAL-PROCESSING MEDIA • SEVERE CORROSION CONDITIONS FOUNDRY REFERENCES SPECIFICALLY IDENTIFY ALLOY B AS RESISTANT TO HYDROCHLORIC ACID. THIS MAKES THE MATERIAL RELEVANT TO DEMANDING CHEMICAL-PROCESSING APPLICATIONS. AMS 5396 APPLICATIONS POTENTIAL APPLICATIONS INCLUDE: CHEMICAL PROCESSING • ACID-PROCESSING EQUIPMENT • CHEMICAL REACTION COMPONENTS • VALVES • PUMPS • IMPELLERS • FITTINGS • CORROSION-RESISTANT COMPONENTS AEROSPACE AND GAS-TURBINE ENVIRONMENTS HISTORICAL LITERATURE IDENTIFIES AMS 5396 INVESTMENT CASTINGS WITH AEROSPACE APPLICATIONS, WHILE THE ALLOY FAMILY IS USED WHERE CORROSION AND ELEVATED-TEMPERATURE PERFORMANCE ARE IMPORTANT. INDUSTRIAL EQUIPMENT • CHEMICAL PUMPS • VALVE COMPONENTS • HEAT-RESISTANT CAST COMPONENTS • CORROSION-RESISTANT HARDWARE • SPECIALIZED MACHINERY COMPONENTS OIL & GAS / PROCESS INDUSTRIES WHERE COMPATIBLE WITH THE SPECIFIC PROCESS CHEMISTRY, NICKEL-MOLYBDENUM ALLOYS CAN BE SELECTED FOR DEMANDING CORROSION ENVIRONMENTS. AMS 5396 ROUND BAR MACHINING IF A CUSTOMER ACTUALLY NEEDS A CYLINDRICAL COMPONENT FROM HASTELLOY B / N10001-TYPE MATERIAL, MACHINING BECOMES A MAJOR CONSIDERATION. NICKEL ALLOYS GENERALLY REQUIRE CONTROLLED MACHINING BECAUSE OF: • WORK HARDENING • HEAT GENERATION • LOW THERMAL CONDUCTIVITY • CUTTING-EDGE WEAR • POTENTIAL SURFACE DAMAGE • STRINGY CHIPS • HIGH CUTTING FORCES RECOMMENDED MACHINING STRATEGY A PRECISION MANUFACTURER SHOULD CONSIDER: • RIGID MACHINE SETUP • SHARP CARBIDE TOOLING • CONTROLLED CUTTING SPEEDS • APPROPRIATE FEED RATES • HIGH-QUALITY CUTTING FLUID • MINIMAL TOOL DWELL • AVOIDING REPEATED PASSES OVER WORK-HARDENED SURFACES • ADEQUATE CHIP EVACUATION • CONTROLLED FINISHING PARAMETERS FOR PRECISION ROUND COMPONENTS, CENTERLESS GRINDING, CNC TURNING, CNC SWISS MACHINING, OR CYLINDRICAL GRINDING MAY BE EMPLOYED DEPENDING ON DIAMETER AND TOLERANCE REQUIREMENTS. TYPICAL ROUND-BAR MANUFACTURING ROUTE FOR A RELATED WROUGHT GRADE IF THE PURCHASER NEEDS AN ACTUAL WROUGHT NICKEL-ALLOY ROUND BAR RATHER THAN AN AMS 5396 CASTING, THE PRODUCTION ROUTE GENERALLY BECOMES: NICKEL-ALLOY CHARGE ↓ VACUUM/CONTROLLED MELTING ↓ BILLET PRODUCTION ↓ HOT FORGING / HOT WORKING ↓ HOMOGENIZATION OR SOLUTION TREATMENT AS APPLICABLE ↓ HOT ROLLING / ROTARY FORGING ↓ HEAT TREATMENT ↓ STRAIGHTENING ↓ PEELING / TURNING ↓ CENTERLESS GRINDING ↓ ULTRASONIC TESTING ↓ DIMENSIONAL INSPECTION ↓ POSITIVE MATERIAL IDENTIFICATION ↓ MECHANICAL TESTING ↓ FINAL CERTIFICATION THE EXACT PROCESS MUST BE SELECTED ACCORDING TO THE WROUGHT SPECIFICATION ACTUALLY ORDERED. QUALITY CONTROL FOR AMS 5396 MANUFACTURING A SERIOUS AMS 5396 SUPPLIER SHOULD ESTABLISH A TRACEABLE QUALITY-CONTROL SYSTEM. CHEMICAL ANALYSIS VERIFICATION MAY INCLUDE: • OPTICAL EMISSION SPECTROSCOPY • XRF WHERE APPROPRIATE • LABORATORY CHEMICAL ANALYSIS • HEAT IDENTIFICATION • CHARGE TRACEABILITY MECHANICAL TESTING DEPENDING ON THE APPLICABLE REVISION AND PURCHASE ORDER: • TENSILE TESTING • YIELD TESTING • ELONGATION • HARDNESS • ELEVATED-TEMPERATURE TESTING WHERE REQUIRED CASTING INSPECTION POTENTIAL INSPECTIONS INCLUDE: • VISUAL INSPECTION • DIMENSIONAL INSPECTION • RADIOGRAPHIC EXAMINATION • LIQUID PENETRANT TESTING • METALLOGRAPHIC EXAMINATION • DEFECT EVALUATION TRACEABILITY EACH PRODUCTION HEAT, CASTING BATCH, TEST SPECIMEN AND CERTIFICATE SHOULD REMAIN TRACEABLE TO THE APPLICABLE PURCHASE ORDER. AMS 5396 CERTIFICATION A MATERIAL CERTIFICATE SHOULD CLEARLY IDENTIFY: • MATERIAL DESIGNATION • SPECIFICATION • REVISION • HEAT NUMBER • CASTING NUMBER • CHEMICAL COMPOSITION • MECHANICAL TEST RESULTS • HEAT-TREATMENT CONDITION • INSPECTION RESULTS • DIMENSIONAL RESULTS WHERE APPLICABLE • SUPPLEMENTARY REQUIREMENTS • MANUFACTURER INFORMATION FOR AEROSPACE PROCUREMENT, THE PURCHASER SHOULD SPECIFICALLY REQUEST THE REQUIRED CERTIFICATION AND INSPECTION DOCUMENTATION RATHER THAN ACCEPTING A GENERIC “HASTELLOY B CERTIFICATE.” AMS 5396 VS AMS 5390, AMS 5391 AND AMS 5397 THESE AMS NUMBERS ARE FREQUENTLY CONFUSED IN ONLINE SEARCHES BECAUSE THEY BELONG TO THE SAME GENERAL FAMILY OF AEROSPACE CASTING SPECIFICATIONS. AMS 5396 HASTELLOY B / NICKEL-MOLYBDENUM ALLOY INVESTMENT CASTINGS AMS 5390 ALLOY X INVESTMENT CASTINGS AMS 5391 IN-713C INVESTMENT CASTINGS AMS 5377 IN-713LC INVESTMENT CASTINGS AMS 5397 IN-100 INVESTMENT CASTINGS AMS 5401 IN-625 INVESTMENT CASTINGS AN INDUSTRIAL CASTING REFERENCE LISTS AMS 5396 WITH ALLOY B AND UNS N10001, WHILE AMS 5391 IS ASSOCIATED WITH IN-713C. THIS DISTINCTION IS CRITICAL FOR SEARCH-ENGINE CONTENT BECAUSE AMS 5396 SHOULD NOT BE DESCRIBED AS IN-713C, ALLOY X, INCONEL 625, OR ANOTHER NICKEL SUPERALLOY. AMS 5396 VS HASTELLOY B-2 ANOTHER COMMON SEARCH-ENGINE CONFUSION IS BETWEEN HASTELLOY B AND HASTELLOY B-2. THEY ARE NOT THE SAME ALLOY. HASTELLOY B UNS N10001 ALLOY B HASTELLOY B-2 UNS N10665 ALLOY B-2 HASTELLOY B-3 UNS N10675 ALLOY B-3 A CASTING-INDUSTRY REFERENCE IDENTIFIES HASTELLOY B AS N10001 AND HASTELLOY B-2 AS N10665) THEREFORE, AN AMS 5396 INQUIRY SHOULD NOT AUTOMATICALLY BE CONVERTED TO B-2.

THIS WORDING PREVENTS THE MOST COMMON TECHNICAL MISTAKE: ORDERING A ROUND BAR AGAINST A CASTING SPECIFICATION WITHOUT IDENTIFYING THE APPROPRIATE WROUGHT STANDARD. FREQUENTLY ASKED QUESTIONS IS AMS 5396 A ROUND-BAR SPECIFICATION? NO. AMS 5396G COVERS INVESTMENT CASTINGS, NOT CONVENTIONAL WROUGHT ROUND BAR. WHAT ALLOY IS AMS 5396? IT IS A CORROSION- AND HEAT-RESISTANT NICKEL-BASE ALLOY IDENTIFIED IN THE CURRENT SPECIFICATION AS APPROXIMATELY 65NI–28MO–5.5FE–0.40V, ASSOCIATED WITH N-12MV AND HASTELLOY B. WHAT IS THE UNS NUMBER FOR HASTELLOY B? UNS N10001 IS ASSOCIATED WITH HASTELLOY B. IS AMS 5396 THE SAME AS ASTM A494 N12MV? THEY ARE CLOSELY RELATED CASTING DESIGNATIONS, BUT THEY SHOULD NOT AUTOMATICALLY BE TREATED AS IDENTICAL SPECIFICATIONS. THE APPLICABLE REQUIREMENTS AND REVISION MUST BE CHECKED. WHAT IS HASTELLOY B USED FOR? IT IS PARTICULARLY ASSOCIATED WITH DEMANDING CORROSION SERVICE, ESPECIALLY REDUCING ENVIRONMENTS AND HYDROCHLORIC-ACID SERVICE. CAN AMS 5396 BE SUPPLIED AS BAR? A SUPPLIER MAY BE ABLE TO SUPPLY A RELATED NICKEL-ALLOY BAR, BUT THE BAR SHOULD BE CERTIFIED TO THE APPROPRIATE WROUGHT SPECIFICATION RATHER THAN SIMPLY ASSUMING AMS 5396 APPLIES TO BAR.
