THE CHEMISTRY SHOWN ABOVE CORRESPONDS TO PUBLISHED ALLOY 230 COMPOSITION LIMITS; EXACT ACCEPTANCE LIMITS SHOULD ALWAYS BE TAKEN FROM THE APPLICABLE PURCHASE SPECIFICATION AND EDITION. WHY TUNGSTEN AND MOLYBDENUM MATTER THE SUBSTANTIAL TUNGSTEN CONTENT CONTRIBUTES TO ELEVATED-TEMPERATURE STRENGTH AND STABILITY, WHILE CHROMIUM PROVIDES OXIDATION RESISTANCE. MOLYBDENUM CONTRIBUTES TO SOLID-SOLUTION STRENGTHENING AND HIGH-TEMPERATURE PERFORMANCE. THE RESULT IS A MATERIAL PARTICULARLY SUITED TO COMPONENTS EXPOSED TO HOT OXIDIZING GASES, THERMAL CYCLING, NITRIDING ATMOSPHERES AND SUSTAINED ELEVATED TEMPERATURES. ALLOY 230 ROUND BAR MANUFACTURING PROCESS MANUFACTURING HIGH-QUALITY UNS N06230 ROUND BAR REQUIRES CAREFUL CONTROL FROM MELTING THROUGH FINAL INSPECTION. 1) RAW MATERIAL SELECTION MANUFACTURING BEGINS WITH CONTROLLED NICKEL-BASED ALLOY CHARGE MATERIALS. TYPICAL CHARGE CONSTITUENTS INCLUDE: • HIGH-PURITY NICKEL • CHROMIUM-BEARING ADDITIONS • TUNGSTEN • MOLYBDENUM • COBALT • IRON • CARBON-CONTROL ADDITIONS • SILICON AND MANGANESE • ALUMINUM • LANTHANUM • BORON BECAUSE ALLOY 230 IS A CHEMISTRY-SENSITIVE HIGH-TEMPERATURE ALLOY, THE MANUFACTURER MUST CAREFULLY CONTROL TRACE ELEMENTS AND MELTING PRACTICE. 2) VACUUM OR CONTROLLED-ATMOSPHERE MELTING DEPENDING ON THE PRODUCER AND PRODUCT ROUTE, NICKEL SUPERALLOYS MAY BE PRODUCED USING CONTROLLED MELTING TECHNOLOGIES SUCH AS: • VACUUM INDUCTION MELTING • VACUUM MELTING • ELECTROSLAG REMELTING WHERE APPLICABLE • SECONDARY REFINING/REMELTING PROCESSES • CONTROLLED-ATMOSPHERE MELTING THE OBJECTIVE IS TO OBTAIN A HOMOGENEOUS CHEMICAL COMPOSITION AND MINIMIZE UNDESIRABLE INCLUSIONS AND SEGREGATION. FOR DEMANDING AEROSPACE, POWER-GENERATION AND HIGH-TEMPERATURE APPLICATIONS, MELTING QUALITY AND TRACEABILITY ARE PARTICULARLY IMPORTANT. 3) HOMOGENIZATION AND CONDITIONING AFTER SOLIDIFICATION, THE INGOT CAN CONTAIN CHEMICAL SEGREGATION. THERMAL HOMOGENIZATION AND CONDITIONING HELP REDISTRIBUTE ALLOYING ELEMENTS BEFORE THERMOMECHANICAL PROCESSING. THE PROCESSING ROUTE MUST BE CONTROLLED TO AVOID: • EXCESSIVE SEGREGATION • SURFACE CRACKING • INTERNAL DEFECTS • UNDESIRABLE GRAIN STRUCTURES • EXCESSIVE CARBIDE FORMATION • FORGING-RELATED DEFECTS 4) HOT WORKING OF ALLOY 230 HOT WORKING IS ONE OF THE MOST IMPORTANT STAGES IN ALLOY 230 ROUND BAR MANUFACTURING. PARMANU DHATU NIGAM STATES THAT ALLOY 230 MAY BE FORGED OR OTHERWISE HOT WORKED AND RECOMMENDS HOLDING THE MATERIAL AT APPROXIMATELY 2150°F (1177°C) FOR SUFFICIENT TIME TO BRING THE ENTIRE SECTION TO TEMPERATURE. TYPICAL MANUFACTURING ROUTES CAN INCLUDE: INGOT → BILLET → HOT FORGING/ROLLING → BAR → HEAT TREATMENT → DESCALING → STRAIGHTENING → MACHINING/GRINDING → INSPECTION THE EXACT SEQUENCE DEPENDS ON DIAMETER, FINAL SURFACE CONDITION AND PURCHASER REQUIREMENTS. 5) FORGING FORGING CAN BE USED TO PRODUCE: • BILLETS • FORGING STOCK • LARGE ROUND BARS • NEAR-NET-SHAPE PREFORMS • COMPONENTS REQUIRING DIRECTIONAL GRAIN CONTROL FOR ALLOY 230 PRODUCTS INTENDED FOR SUBSEQUENT FORGING, ASTM B472 IS ESPECIALLY IMPORTANT. ASTM IDENTIFIES B472 AS THE SPECIFICATION COVERING NICKEL-ALLOY BILLETS AND BARS FOR REFORGING AND SPECIFICALLY INCLUDES UNS N06230. 6) HOT ROLLING HOT ROLLING IS ANOTHER COMMON ROUTE FOR PRODUCING ALLOY 230 BAR. THE BILLET IS PROGRESSIVELY REDUCED THROUGH CONTROLLED DEFORMATION TO ACHIEVE THE REQUIRED CROSS-SECTIONAL DIMENSIONS. IMPORTANT VARIABLES INCLUDE: • STARTING TEMPERATURE • FINISHING TEMPERATURE • REDUCTION PER PASS • TOTAL REDUCTION • ROLLING SPEED • COOLING RATE • GRAIN STRUCTURE • SURFACE CONDITION POOR TEMPERATURE CONTROL CAN CAUSE SURFACE DEFECTS OR AFFECT THE RESULTING MICROSTRUCTURE. 7) COLD WORKING ALLOY 230 HAS GOOD DUCTILITY AND CAN BE COLD WORKED. COLD WORKING MAY BE USED WHERE TIGHTER DIMENSIONS, IMPROVED SURFACE FINISH OR SPECIFIC MECHANICAL PROPERTIES ARE REQUIRED. POTENTIAL PROCESSES INCLUDE: • COLD DRAWING • COLD SIZING • CENTERLESS GRINDING • PRECISION TURNING • PEELING THE AMOUNT OF COLD REDUCTION MUST BE CONTROLLED BECAUSE COLD WORK CAN SUBSTANTIALLY AFFECT HARDNESS AND MECHANICAL PROPERTIES. 8) SOLUTION HEAT TREATMENT HEAT TREATMENT IS CRITICAL FOR OBTAINING THE REQUIRED METALLURGICAL CONDITION. THE EXACT TEMPERATURE, HOLDING TIME AND COOLING METHOD SHOULD BE SELECTED ACCORDING TO THE APPLICABLE MATERIAL SPECIFICATION, PRODUCT FORM AND PURCHASER REQUIREMENTS. FOR SPECIFICATION-CONTROLLED PRODUCTION, THE MANUFACTURER SHOULD DOCUMENT: • FURNACE IDENTIFICATION • HEAT NUMBER • CHARGE TEMPERATURE • SOAKING TEMPERATURE • SOAKING TIME • FURNACE ATMOSPHERE • COOLING METHOD • ACTUAL FURNACE CYCLE • LOT TRACEABILITY A CERTIFICATE SHOULD NOT SIMPLY STATE 'HEAT TREATED'; IT SHOULD IDENTIFY THE APPLICABLE CONDITION AND SPECIFICATION. 9) DESCALING AND SURFACE CONDITIONING FOLLOWING HOT WORKING AND HEAT TREATMENT, OXIDE SCALE CAN BE REMOVED USING APPROPRIATE INDUSTRIAL METHODS. POSSIBLE FINISHING OPERATIONS INCLUDE: • PICKLING • MECHANICAL DESCALING • GRINDING • CENTERLESS GRINDING • PEELING • TURNING • POLISHING ASTM B572 SPECIFICALLY DESCRIBES ROD PRODUCTS IN DIFFERENT DIMENSIONAL AND SURFACE CONDITIONS, INCLUDING HOT- OR COLD-FINISHED PRODUCTS AND SOLUTION-ANNEALED PRODUCTS WITH PICKLED, MECHANICALLY DESCALED, GROUND OR TURNED SURFACES DEPENDING ON SIZE/PRODUCT CONDITION. 10) STRAIGHTENING ROUND BARS MUST SATISFY DIMENSIONAL AND STRAIGHTNESS REQUIREMENTS. DEPENDING ON SIZE AND FINAL CONDITION, STRAIGHTENING MAY BE PERFORMED USING CONTROLLED MECHANICAL EQUIPMENT. EXCESSIVE STRAIGHTENING SHOULD BE AVOIDED BECAUSE IT CAN INTRODUCE UNDESIRABLE RESIDUAL STRESSES OR DIMENSIONAL VARIATION. 11) PRECISION MACHINING ALLOY 230 ROUND BAR CAN BE SUPPLIED IN MACHINING-READY CONDITIONS. TYPICAL FINISHING PROCESSES INCLUDE: • CNC TURNING • CENTERLESS GRINDING • PEELING • PRECISION GRINDING • THREADING • CUTTING TO LENGTH • CHAMFERING • POLISHING BECAUSE ALLOY 230 IS A HIGH-PERFORMANCE NICKEL ALLOY, TOOLING AND CUTTING CONDITIONS MUST BE SELECTED SPECIFICALLY FOR NICKEL-BASED SUPERALLOYS. 12) INSPECTION AND QUALITY CONTROL A PROFESSIONAL ALLOY 230 MANUFACTURER SHOULD ESTABLISH INSPECTION PROCEDURES COVERING: CHEMICAL ANALYSIS VERIFICATION OF: • NI • CR • W • MO • CO • FE • C • MN • SI • AL • LA • B • P • S • TI • CU MECHANICAL TESTING DEPENDING ON THE APPLICABLE SPECIFICATION: • TENSILE STRENGTH • YIELD STRENGTH • ELONGATION • HARDNESS ASTM B572 REQUIRES CHEMICAL ANALYSIS AND MECHANICAL TESTING FOR COVERED ROD PRODUCTS. DIMENSIONAL INSPECTION TYPICAL CHECKS INCLUDE: • OUTSIDE DIAMETER • LENGTH • OVALITY • STRAIGHTNESS • SURFACE ROUGHNESS WHERE SPECIFIED NON-DESTRUCTIVE TESTING WHEN REQUIRED BY PURCHASE ORDER OR APPLICATION, ADDITIONAL NDT MAY INCLUDE: • ULTRASONIC TESTING • LIQUID PENETRANT TESTING • EDDY-CURRENT TESTING • VISUAL INSPECTION ASTM STANDARDS FOR ALLOY 230 ROUND BAR ASTM B572 ASTM B572-24 IS THE PRINCIPAL CURRENT ASTM ROD SPECIFICATION IDENTIFIED BY ASTM FOR ALLOY 230.
