FOR EXAMPLE: HASTELLOY X / UNS N06002 / ROUND BAR / ASTM B572 OR HASTELLOY X / UNS N06002 / BAR / AMS 5754 AMS 5390 INVESTMENT CASTING MANUFACTURING PROCESS BECAUSE AMS 5390 COVERS INVESTMENT CASTINGS, ITS MANUFACTURING ROUTE DIFFERS SUBSTANTIALLY FROM CONVENTIONAL WROUGHT ROUND-BAR PRODUCTION. 1) RAW MATERIAL SELECTION THE FOUNDRY BEGINS WITH CONTROLLED NICKEL-BASE ALLOY CHARGE MATERIAL. TYPICAL CHARGE MATERIALS INCLUDE: • NICKEL • CHROMIUM-BEARING ADDITIONS • MOLYBDENUM • IRON • COBALT • TUNGSTEN • CARBON-CONTROL ADDITIONS • OTHER CONTROLLED ALLOYING ADDITIONS CHARGE MATERIALS SHOULD BE TRACEABLE AND VERIFIED AGAINST THE APPLICABLE CHEMISTRY REQUIREMENTS. 2) MELTING NICKEL-BASED SUPERALLOYS REQUIRE CONTROLLED MELTING TO ACHIEVE THE REQUIRED CHEMISTRY AND CLEANLINESS. INDUSTRIAL MELTING MAY USE PROCESSES SUCH AS: • VACUUM INDUCTION MELTING • CONTROLLED-ATMOSPHERE MELTING • INDUCTION MELTING • VACUUM-ASSISTED MELTING • REMELTING/REFINING PROCESSES WHERE REQUIRED BY THE MANUFACTURING ROUTE THE OBJECTIVE IS TO OBTAIN HOMOGENEOUS ALLOY CHEMISTRY WHILE MINIMIZING CONTAMINATION AND UNDESIRABLE INCLUSIONS. 3) INVESTMENT PATTERN PRODUCTION FOR PRECISION INVESTMENT CASTING: 1. PRODUCE THE WAX OR POLYMER PATTERN. 2. ASSEMBLE PATTERNS ONTO A TREE. 3. APPLY CERAMIC SLURRY. 4. BUILD SUCCESSIVE REFRACTORY LAYERS. 5. DRY AND CURE THE CERAMIC SHELL. 6. REMOVE THE WAX PATTERN. 7. PREHEAT THE MOLD. 8. POUR THE MOLTEN ALLOY. 9. SOLIDIFY UNDER CONTROLLED CONDITIONS. 10. BREAK AWAY THE CERAMIC SHELL. 11. CUT INDIVIDUAL CASTINGS FROM THE TREE. 12. PERFORM FINISHING OPERATIONS. INVESTMENT CASTING IS PARTICULARLY VALUABLE WHEN COMPLEX GEOMETRY, THIN SECTIONS AND NEAR-NET-SHAPE COMPONENTS ARE REQUIRED. HASTELLOY X ROUND BAR MANUFACTURING PROCESS A GENUINE HASTELLOY X ROUND BAR MANUFACTURING ROUTE IS DIFFERENT FROM AMS 5390 INVESTMENT CASTING. A TYPICAL WROUGHT-BAR ROUTE CONSISTS OF: STEP 1 — VACUUM OR CONTROLLED MELTING HIGH-PURITY RAW MATERIALS ARE MELTED UNDER CONTROLLED CONDITIONS. STEP 2 — INGOT PRODUCTION THE MOLTEN ALLOY IS CAST INTO AN INGOT OR SUITABLE PRIMARY FORM. STEP 3 — HOMOGENIZATION CONTROLLED THERMAL TREATMENT MAY BE USED TO REDUCE CHEMICAL SEGREGATION AND PREPARE THE INGOT FOR HOT WORKING. STEP 4 — HOT FORGING THE MATERIAL IS FORGED WITHIN A CONTROLLED TEMPERATURE RANGE. HOT FORGING CAN CONVERT THE CAST STRUCTURE INTO A MORE SUITABLE WROUGHT MICROSTRUCTURE. STEP 5 — BREAKDOWN ROLLING / FORGING LARGE SECTIONS ARE PROGRESSIVELY REDUCED. STEP 6 — HEAT TREATMENT THE BAR RECEIVES THE HEAT TREATMENT REQUIRED BY THE GOVERNING SPECIFICATION AND PURCHASE ORDER. STEP 7 — DESCALING OXIDE SCALE GENERATED DURING THERMAL PROCESSING IS REMOVED USING SUITABLE MECHANICAL OR CHEMICAL METHODS. STEP 8 — COLD DRAWING OR PRECISION SIZING WHERE REQUIRED, COLD WORKING CAN IMPROVE DIMENSIONAL ACCURACY AND SURFACE CONDITION. STEP 9 — STRAIGHTENING BARS ARE STRAIGHTENED TO ACHIEVE THE REQUIRED DIMENSIONAL AND GEOMETRIC TOLERANCES. STEP 10 — MACHINING THE MATERIAL CAN BE CENTERLESS GROUND, PEELED, TURNED OR OTHERWISE FINISHED TO THE CUSTOMER'S DIMENSIONAL REQUIREMENTS. STEP 11 — INSPECTION TYPICAL QUALITY-CONTROL OPERATIONS CAN INCLUDE: • CHEMICAL ANALYSIS • TENSILE TESTING • HARDNESS TESTING • DIMENSIONAL INSPECTION • SURFACE INSPECTION • ULTRASONIC TESTING WHERE SPECIFIED • METALLOGRAPHIC EXAMINATION WHERE REQUIRED • TRACEABILITY VERIFICATION • MATERIAL-TEST-REPORT REVIEW WHY HASTELLOY X IS USED AT HIGH TEMPERATURE HASTELLOY X IS A NICKEL-CHROMIUM-IRON-MOLYBDENUM ALLOY DEVELOPED FOR DEMANDING HIGH-TEMPERATURE ENVIRONMENTS. ITS MAJOR ADVANTAGES INCLUDE: • HIGH-TEMPERATURE STRENGTH • OXIDATION RESISTANCE • GOOD CORROSION RESISTANCE • RESISTANCE TO CARBURIZING ATMOSPHERES • GOOD FABRICABILITY • GOOD WELDABILITY • RESISTANCE TO THERMAL DEGRADATION • USEFUL CREEP AND STRESS-RUPTURE PERFORMANCE TECHNICAL REFERENCES DESCRIBE HASTELLOY X AS SUITABLE FOR HIGH-TEMPERATURE APPLICATIONS INCLUDING GAS TURBINES, INDUSTRIAL FURNACES, HEAT-TREATMENT EQUIPMENT AND AEROSPACE COMPONENTS. HASTELLOY X ROUND BAR APPLICATIONS HASTELLOY X ROUND BAR IS USED WHERE DESIGNERS NEED A COMBINATION OF HIGH-TEMPERATURE CAPABILITY AND CORROSION/OXIDATION RESISTANCE. TYPICAL APPLICATIONS INCLUDE: AEROSPACE • JET-ENGINE COMPONENTS • EXHAUST-SYSTEM COMPONENTS • AFTERBURNER COMPONENTS • COMBUSTION-SYSTEM COMPONENTS • TURBINE-RELATED HARDWARE • HIGH-TEMPERATURE FASTENERS • STRUCTURAL HIGH-TEMPERATURE COMPONENTS GAS TURBINE • TURBINE HARDWARE • COMBUSTION COMPONENTS • HEAT SHIELDS • HOT-SECTION COMPONENTS INDUSTRIAL FURNACES • FURNACE FIXTURES • HEAT-TREATMENT COMPONENTS • SUPPORTS • HIGH-TEMPERATURE SHAFTS • RETAINING COMPONENTS CHEMICAL PROCESSING • HIGH-TEMPERATURE PROCESS EQUIPMENT • CORROSION-RESISTANT COMPONENTS • FURNACE COMPONENTS • HIGH-TEMPERATURE PIPING-RELATED HARDWARE POWER GENERATION • COMBUSTION COMPONENTS • HOT-GAS COMPONENTS • HIGH-TEMPERATURE FIXTURES • SPECIALIZED TURBINE HARDWARE EOS IDENTIFIES UNS N06002 / AMS 5390 WITHIN ITS NICKEL-ALLOY MATERIAL DOCUMENTATION AND LISTS APPLICATIONS INCLUDING INDUSTRIAL GAS TURBINES, MICROTURBINES, TURBOCHARGERS, INSTRUMENTATION AND POWER/PROCESS-INDUSTRY COMPONENTS. HASTELLOY X ROUND BAR SIZES MANUFACTURERS MAY SUPPLY ROUND BAR IN: • METRIC DIAMETERS • INCH DIAMETERS • SMALL-DIAMETER PRECISION BARS • LARGE-DIAMETER FORGED BARS • CUSTOM DIAMETERS • CUT-TO-LENGTH PIECES • BRIGHT-FINISHED BAR • GROUND BAR • PEELED BAR • COLD-DRAWN BAR • HOT-FINISHED BAR • FORGED BAR AVAILABLE DIMENSIONS DEPEND ON THE MILL, MANUFACTURING ROUTE, SPECIFICATION, HEAT-TREATMENT CAPABILITY AND CUSTOMER REQUIREMENTS. A PURCHASE ORDER SHOULD SPECIFY: DIAMETER × LENGTH × SPECIFICATION × GRADE × CONDITION × FINISH × INSPECTION REQUIREMENTS. SURFACE FINISHES FOR HASTELLOY X ROUND BAR COMMON FINISHING ROUTES INCLUDE: HOT FINISHED ECONOMICAL FOR LARGER DIAMETERS BUT NORMALLY REQUIRES ADDITIONAL SURFACE CONDITIONING. COLD DRAWN PROVIDES TIGHTER DIMENSIONAL CONTROL AND IMPROVED SURFACE QUALITY. PEELED REMOVES THE OUTER SURFACE LAYER AFTER HOT WORKING. CENTERLESS GROUND USED WHERE PRECISION DIAMETER AND SURFACE FINISH ARE REQUIRED. BRIGHT BAR A GENERAL COMMERCIAL TERM FOR A BAR RECEIVING ADDITIONAL SURFACE FINISHING. POLISHED BAR USED WHERE A CONTROLLED VISUAL OR SURFACE FINISH IS REQUIRED. MACHINING HASTELLOY X ROUND BAR HASTELLOY X IS A RELATIVELY DEMANDING NICKEL ALLOY TO MACHINE. IMPORTANT MACHINING CONSIDERATIONS INCLUDE: • USE RIGID MACHINE SETUPS. • AVOID EXCESSIVE TOOL DWELL. • MAINTAIN POSITIVE CUTTING ACTION. • USE SUITABLE CARBIDE OR OTHER APPROPRIATE TOOLING. • CONTROL HEAT GENERATION. • USE ADEQUATE COOLANT/LUBRICATION. • AVOID WORK HARDENING. • MAINTAIN CONSISTENT FEED. • AVOID RUBBING RATHER THAN CUTTING. • USE SHARP TOOLING. BECAUSE NICKEL ALLOYS CAN WORK HARDEN RAPIDLY, INTERRUPTED CUTS AND EXCESSIVE TOOL RUBBING CAN MAKE MACHINING SUBSTANTIALLY MORE DIFFICULT. WELDING HASTELLOY X HASTELLOY X IS WELDABLE, BUT WELDING PROCEDURES MUST BE DEVELOPED AND QUALIFIED FOR THE EXACT APPLICATION. COMMON CONSIDERATIONS INCLUDE: • JOINT CLEANLINESS • HEAT INPUT • INTERPASS TEMPERATURE • SHIELDING GAS QUALITY • FILLER-METAL SELECTION • JOINT DESIGN • PRE- AND POST-WELD REQUIREMENTS • WELDING PROCEDURE QUALIFICATION • FINAL INSPECTION FOR WELDING CONSUMABLES, TECHNICAL REFERENCES ASSOCIATE HASTELLOY X WITH AWS A5.14 ERNICRMO-2 / AMS 5798 WIRE AND AWS A5.11 ENICRMO-2 ELECTRODES.
