ALLOY X ROUND BAR CHEMICAL COMPOSITION ALLOY X DERIVES ITS HIGH-TEMPERATURE PERFORMANCE FROM A NICKEL MATRIX STRENGTHENED PRIMARILY BY CHROMIUM, MOLYBDENUM, IRON AND OTHER ALLOYING ELEMENTS. A COMMONLY REFERENCED COMPOSITION RANGE IS: ELEMENT - TYPICAL / SPECIFIED RANGE NICKEL BALANCE CHROMIUM 20.5–23.0% IRON 17.0–20.0% MOLYBDENUM 8.0–10.0% COBALT 0.5–2.5% TUNGSTEN 0.2–1.0% CARBON 0.05–0.15% MANGANESE ≤1.0% SILICON ≤1.0% ALUMINUM ≤0.5% TITANIUM ≤0.15% BORON TYPICALLY VERY LOW PUBLISHED ALLOY X DATA GIVES A NOMINAL CHEMISTRY AROUND 47% NI, 22% CR, 18% FE, 9% MO, 1.5% CO AND 0.6% W, WITH CONTROLLED MINOR ELEMENTS. EXACT LIMITS DEPEND ON THE APPLICABLE PRODUCT SPECIFICATION. FOR MANUFACTURING, THE PURCHASE SPECIFICATION TAKES PRECEDENCE OVER GENERIC CHEMISTRY TABLES. HOW ALLOY X ROUND BAR IS MANUFACTURED MANUFACTURING ALLOY X ROUND BAR REQUIRES CONSIDERABLY TIGHTER PROCESS CONTROL THAN ORDINARY CARBON OR STAINLESS STEEL BAR. THE TYPICAL MANUFACTURING ROUTE IS: RAW MATERIAL SELECTION → MELTING → REFINING → INGOT/BILLET → HOMOGENIZATION → HOT FORGING/HOT ROLLING → SOLUTION HEAT TREATMENT → COOLING → STRAIGHTENING → TURNING/PEELING → GRINDING/POLISHING → INSPECTION → MARKING → PACKING EACH STAGE CONTRIBUTES TO THE FINAL METALLURGICAL QUALITY OF THE BAR. 1) RAW MATERIAL SELECTION HIGH-PURITY NICKEL, CHROMIUM, IRON, MOLYBDENUM AND OTHER REQUIRED ALLOYING ADDITIONS ARE SELECTED ACCORDING TO THE APPLICABLE ALLOY X SPECIFICATION. RAW MATERIALS SHOULD BE: • TRACEABLE • CHEMICALLY VERIFIED • SUITABLE FOR VACUUM MELTING • FREE FROM UNACCEPTABLE CONTAMINATION • CONTROLLED FOR TRAMP AND RESIDUAL ELEMENTS FOR AEROSPACE-GRADE APPLICATIONS, COMPLETE HEAT TRACEABILITY IS PARTICULARLY IMPORTANT. 2) VACUUM MELTING AND ALLOY PRODUCTION NICKEL SUPERALLOYS SUCH AS ALLOY X ARE COMMONLY PRODUCED USING CONTROLLED MELTING TECHNOLOGY. DEPENDING ON THE PRODUCER AND REQUIRED QUALITY LEVEL, MELTING MAY INVOLVE: • VACUUM INDUCTION MELTING (VIM) • ELECTROSLAG REMELTING (ESR) • VACUUM ARC REMELTING (VAR) • OTHER CONTROLLED MELTING/REFINING PRACTICES THE PURPOSE IS TO OBTAIN A CHEMICALLY HOMOGENEOUS ALLOY WHILE CONTROLLING GASES, INCLUSIONS AND UNDESIRABLE RESIDUAL ELEMENTS. FOR CRITICAL AEROSPACE MATERIAL, THE MELT ROUTE AND REMELTING REQUIREMENTS SHOULD BE SPECIFIED ON THE PURCHASE ORDER RATHER THAN ASSUMED. 3) INGOT AND BILLET PRODUCTION THE MOLTEN ALLOY IS CONVERTED INTO AN INGOT OR SUITABLE BILLET. THE BILLET IS THEN PREPARED FOR SUBSEQUENT HOT WORKING. IMPORTANT MANUFACTURING CONTROLS INCLUDE: • INGOT SOUNDNESS • MACROSTRUCTURE • SEGREGATION CONTROL • SURFACE CONDITION • INTERNAL DISCONTINUITY CONTROL • HEAT IDENTIFICATION • CHEMICAL TRACEABILITY THE BILLET IS THE STARTING POINT FOR PRODUCING HIGH-QUALITY ALLOY X ROUND BAR. 4) HOMOGENIZATION DEPENDING ON THE MANUFACTURING ROUTE, THE ALLOY X BILLET MAY UNDERGO A CONTROLLED THERMAL TREATMENT BEFORE HOT WORKING. HOMOGENIZATION HELPS REDUCE CHEMICAL SEGREGATION AND PREPARES THE MICROSTRUCTURE FOR FORGING OR ROLLING. TEMPERATURE, SOAK TIME AND COOLING RATE SHOULD BE ESTABLISHED ACCORDING TO THE PRODUCER'S QUALIFIED PROCESS AND GOVERNING MATERIAL SPECIFICATION. 5) HOT FORGING OF ALLOY X ROUND BAR HOT FORGING IS AN IMPORTANT ROUTE FOR PRODUCING LARGER ALLOY X BAR SIZES. THE BILLET IS HEATED INTO THE APPROPRIATE HOT-WORKING RANGE AND SUBJECTED TO CONTROLLED DEFORMATION. THE OBJECTIVE IS TO: • BREAK DOWN THE CAST STRUCTURE • REFINE AND REDISTRIBUTE THE MICROSTRUCTURE • IMPROVE INTERNAL SOUNDNESS • PRODUCE THE REQUIRED CROSS-SECTION • CONTROL GRAIN STRUCTURE • REDUCE SEGREGATION-RELATED EFFECTS BECAUSE NICKEL ALLOYS RESIST DEFORMATION MORE STRONGLY THAN CONVENTIONAL STEELS, FORGING EQUIPMENT AND TEMPERATURE CONTROL ARE CRITICAL. 6) HOT ROLLING FOR SUITABLE DIMENSIONS, ALLOY X MAY ALSO BE PROCESSED THROUGH HOT ROLLING. DURING ROLLING, THE BILLET PASSES THROUGH A SEQUENCE OF REDUCTIONS UNTIL THE REQUIRED ROUND-BAR DIAMETER IS APPROACHED. PROCESS CONTROL INCLUDES: • FURNACE TEMPERATURE • BILLET TEMPERATURE • REDUCTION PER PASS • ROLLING SPEED • SURFACE CONDITION • FINAL DIMENSIONAL ACCURACY POOR HOT-WORKING CONTROL CAN RESULT IN SURFACE CRACKING, UNDESIRABLE GRAIN STRUCTURE OR DIMENSIONAL PROBLEMS. 7) SOLUTION HEAT TREATMENT SOLUTION HEAT TREATMENT IS ONE OF THE MOST IMPORTANT STEPS IN ALLOY X ROUND BAR MANUFACTURING. THE BAR IS HEATED TO A CONTROLLED SOLUTION-TREATMENT TEMPERATURE TO ESTABLISH THE REQUIRED METALLURGICAL CONDITION, FOLLOWED BY THE SPECIFIED COOLING PROCEDURE. FOR ALLOY X, MANUFACTURERS COMMONLY ASSOCIATE SOLUTION TREATMENT WITH APPROXIMATELY 2150°F / 1177°C, ALTHOUGH THE EXACT TREATMENT MUST FOLLOW THE GOVERNING SPECIFICATION AND QUALIFIED PRODUCER PROCEDURE. A PUBLISHED FABRICATION REFERENCE ALSO RECOMMENDS ANNEALING AFTER SEVERE FORMING AT APPROXIMATELY 2150°F, WITH RAPID AIR COOLING. THE PURPOSE IS TO OBTAIN A STABLE, SUITABLE MICROSTRUCTURE AND RESTORE DUCTILITY AFTER SIGNIFICANT HOT OR COLD WORKING. 8) COOLING COOLING FROM SOLUTION-TREATMENT TEMPERATURE MUST BE CONTROLLED. DEPENDING ON THE APPLICABLE SPECIFICATION AND PRODUCT CONDITION, COOLING CAN INVOLVE: • AIR COOLING • RAPID COOLING • OTHER SPECIFIED COOLING PROCEDURES THE COOLING PROCEDURE SHOULD NEVER BE SELECTED SOLELY FROM A GENERIC ONLINE DATASHEET. THE ORDERED SPECIFICATION AND MATERIAL CONDITION CONTROL THE FINAL PROCEDURE. 9) STRAIGHTENING AFTER HEAT TREATMENT, ALLOY X ROUND BAR CAN UNDERGO CONTROLLED STRAIGHTENING. STRAIGHTENING MUST AVOID EXCESSIVE RESIDUAL STRESS OR SURFACE DAMAGE. TYPICAL QUALITY CHECKS INCLUDE: • STRAIGHTNESS • DIAMETER • OVALITY • SURFACE CONDITION 10) TURNING AND PEELING HOT-FORGED OR HOT-ROLLED BAR MAY BE SUPPLIED WITH A ROUGH SURFACE. PRECISION TURNING OR PEELING REMOVES THE OUTER SURFACE LAYER AND IMPROVES: • DIAMETER ACCURACY • SURFACE FINISH • CONCENTRICITY • DEFECT REMOVAL • MACHINABILITY THIS IS ESPECIALLY USEFUL FOR CUSTOMERS PURCHASING PRECISION ALLOY X BAR FOR CNC MACHINING. 11) GRINDING AND POLISHING FOR BRIGHT OR PRECISION-FINISHED ALLOY X ROUND BAR, GRINDING CAN PRODUCE A SMOOTHER SURFACE. POSSIBLE FINISHES INCLUDE: • ROUGH TURNED • PEELED • GROUND • BRIGHT FINISH • POLISHED FINISH THE REQUIRED FINISH SHOULD BE CLEARLY SPECIFIED BECAUSE SURFACE-TREATMENT REQUIREMENTS DIFFER BETWEEN APPLICATIONS. 12) COLD DRAWING AND PRECISION SIZING SMALLER ALLOY X BARS OR RODS MAY UNDERGO COLD WORKING FOR DIMENSIONAL PRECISION. COLD WORKING CAN IMPROVE: • DIMENSIONAL TOLERANCE • SURFACE FINISH • STRAIGHTNESS • MECHANICAL STRENGTH HOWEVER, COLD DEFORMATION ALSO CHANGES THE MATERIAL'S WORK-HARDENED CONDITION, SO SUBSEQUENT HEAT TREATMENT REQUIREMENTS MUST BE CONSIDERED. ALLOY X ROUND BAR MECHANICAL PROPERTIES PUBLISHED DATA FOR SOLUTION-TREATED ALLOY X BAR COMMONLY REPORTS ROOM-TEMPERATURE TENSILE STRENGTH IN THE APPROXIMATE 690–785 MPA RANGE, DEPENDING ON SPECIFICATION, PRODUCT CONDITION AND TEST REQUIREMENTS. ONE TECHNICAL SOURCE GIVES TYPICAL SOLUTION-ANNEALED BAR VALUES OF APPROXIMATELY: • TENSILE STRENGTH: 755 MPA • 0.2% YIELD STRENGTH: 385 MPA • ELONGATION: APPROXIMATELY 45% THESE FIGURES SHOULD BE TREATED AS REPRESENTATIVE RATHER THAN UNIVERSAL CERTIFICATION VALUES. THE MTR/TEST CERTIFICATE FOR THE SPECIFIC HEAT AND PRODUCT CONTROLS. HIGH-TEMPERATURE PERFORMANCE OF ALLOY X ONE OF THE PRINCIPAL REASONS CUSTOMERS SPECIFY ALLOY X IS ITS HIGH-TEMPERATURE CAPABILITY. THE ALLOY COMBINES: • HIGH-TEMPERATURE STRENGTH • OXIDATION RESISTANCE • THERMAL STABILITY • GOOD FABRICABILITY • GOOD WELDABILITY • RESISTANCE TO CARBURIZING ENVIRONMENTS HAYNES DESCRIBES HASTELLOY X AS PROVIDING A BALANCE OF HIGH-TEMPERATURE STRENGTH, OXIDATION RESISTANCE AND FABRICABILITY, WITH APPLICATIONS IN AIRCRAFT AND INDUSTRIAL GAS-TURBINE ENGINE COMPONENTS.
