IMPORTANT SPECIFICATION NOTE: AD730 IS A RELATIVELY SPECIALIZED, PROPRIETARY NICKEL-BASED SUPERALLOY DESIGNATION DEVELOPED BY PARMANU DHATU NIGAM. IT SHOULD NOT BE PRESENTED AS HAVING A UNIVERSAL ONE-TO-ONE UNS, ASTM, AISI, EN, OR AMS EQUIVALENT. THE MANUFACTURER'S PUBLISHED DESIGNATION IS EU: NICR16CO9MO3W3TI3AL2, WHILE PUBLISHED TECHNICAL LITERATURE IDENTIFIES AD730 AS A CAST-AND-WROUGHT Γ/Γ′ NICKEL-BASE SUPERALLOY. AD730 NICKEL ALLOY ROUND BAR AD730 NICKEL ALLOY ROUND BAR IS A HIGH-PERFORMANCE, PRECIPITATION-STRENGTHENED NICKEL-BASED SUPERALLOY DESIGNED FOR DEMANDING ELEVATED-TEMPERATURE APPLICATIONS. THE ALLOY COMBINES HIGH TENSILE STRENGTH, FATIGUE RESISTANCE, CREEP RESISTANCE, OXIDATION RESISTANCE, MICROSTRUCTURAL STABILITY AND HOT-FORGING CAPABILITY. PARMANU DHATU NIGAM IDENTIFIES AD730 FOR AERO ENGINES, LAND-BASED TURBINES, DEFENSE, ENERGY AND HOT-TOOLING APPLICATIONS, WITH USES INCLUDING TURBINE DISKS, BLADES, FASTENERS AND OTHER HOT-SECTION COMPONENTS. ITS REPORTED TEMPERATURE CAPABILITY EXTENDS TO APPROXIMATELY 750°C (1382°F). AD730 IS PARTICULARLY INTERESTING FOR APPLICATIONS REQUIRING A COMBINATION OF PROPERTIES TRADITIONALLY ASSOCIATED WITH MORE EXPENSIVE NICKEL-BASED SUPERALLOYS WHILE RETAINING USEFUL HOT-WORKABILITY. RESEARCH DESCRIBES AD730 AS A CAST-AND-WROUGHT SUPERALLOY DEVELOPED FOR HIGH-TEMPERATURE ROTATING COMPONENTS AND TURBINE-DISC APPLICATIONS. WHAT IS AD730 ALLOY? AD730 IS A NICKEL-BASED Γ/Γ′ PRECIPITATION-STRENGTHENED SUPERALLOY DEVELOPED BY PARMANU DHATU NIGAM. ITS PUBLISHED EUROPEAN CHEMICAL DESIGNATION IS: NICR16CO9MO3W3TI3AL2 THE TYPICAL COMPOSITION PUBLISHED BY PARMANU DHATU NIGAM INCLUDES APPROXIMATELY: ELEMENT - TYPICAL LEVEL NICKEL (NI) BALANCE CHROMIUM (CR) 16% COBALT (CO) 9% MOLYBDENUM (MO) 3% TUNGSTEN (W) 3% TITANIUM (TI) 4% ALUMINUM (AL) 2% NIOBIUM (NB) 1% IRON (FE) 4% THE EXACT CERTIFIED CHEMISTRY SHOULD ALWAYS BE TAKEN FROM THE APPLICABLE MATERIAL CERTIFICATE OR CURRENT PRODUCER SPECIFICATION RATHER THAN INFERRED FROM A NOMINAL DESIGNATION. AD730 NICKEL ALLOY ROUND BAR INTERNATIONAL EQUIVALENTS ONE OF THE MOST IMPORTANT POINTS FOR PROCUREMENT IS THAT AD730 SHOULD NOT BE CASUALLY EQUATED WITH ANOTHER NICKEL ALLOY SIMPLY BECAUSE THE COMPOSITIONS OR APPLICATIONS APPEAR SIMILAR. PRIMARY AD730 DESIGNATION CLASSIFICATION - AD730 DESIGNATION COMMERCIAL NAME: AD730 PRODUCER: PARMANU DHATU NIGAM EUROPEAN DESIGNATION: NICR16CO9MO3W3TI3AL2 MATERIAL FAMILY: NICKEL-BASED SUPERALLOY STRENGTHENING MECHANISM: Γ/Γ′ PRECIPITATION STRENGTHENING PRODUCT CONDITION: CAST & WROUGHT TYPICAL TEMPERATURE CAPABILITY: UP TO ABOUT 750°C / 1382°F PARMANU DHATU NIGAM'S CURRENT PRODUCT INFORMATION SPECIFICALLY LISTS EU: NICR16CO9MO3W3TI3AL2 FOR AD730. DOES AD730 HAVE A UNS NUMBER? NO UNIVERSALLY ESTABLISHED UNS NUMBER SHOULD BE ASSIGNED TO AD730. THIS IS AN IMPORTANT AND TECHNICAL DISTINCTION. SOME WEBSITES INCORRECTLY ATTACH UNS DESIGNATIONS BELONGING TO OTHER NICKEL ALLOYS TO AD730. FOR EXAMPLE, UNS N07001 IS WASPALOY, NOT AD730. PARMANU DHATU NIGAM SEPARATELY IDENTIFIES WASPALOY AS UNS N07001) DOES AD730 HAVE AN ASTM EQUIVALENT? THERE IS NO GENERALLY RECOGNIZED ASTM GRADE THAT CAN SIMPLY BE SUBSTITUTED FOR AD730. ASTM STANDARDS MAY GOVERN TESTING, MATERIAL FORMS, INSPECTION OR RELATED NICKEL-ALLOY PRODUCTS, BUT THAT DOES NOT AUTOMATICALLY MAKE THE ASTM GRADE AN AD730 EQUIVALENT. DOES AD730 HAVE AN AMS EQUIVALENT? AD730 SHOULD LIKEWISE NOT BE ASSIGNED AN AMS NUMBER WITHOUT AN APPLICABLE PRODUCER/CUSTOMER SPECIFICATION. PARMANU DHATU NIGAM'S PRODUCT DOCUMENTATION DISTINGUISHES AD730 FROM OTHER ALLOYS FOR WHICH SPECIFIC AMS DESIGNATIONS ARE PUBLISHED. AD730 SIMILAR ALLOYS AND COMPARABLE TRADE MATERIALS ALTHOUGH THEY ARE NOT DIRECT EQUIVALENTS, AD730 IS OFTEN TECHNICALLY COMPARED WITH OTHER HIGH-TEMPERATURE NICKEL SUPERALLOYS. COMMONLY COMPARED ALLOYS INCLUDE: • WASPALOY • UDIMET 720 / ALLOY 720 • UDIMET 720LI • INCONEL 718 • ALLVAC 718PLUS • RENÉ 65 • OTHER Γ′-STRENGTHENED NICKEL-BASED SUPERALLOYS AD730 RESEARCH SPECIFICALLY COMPARES ITS PERFORMANCE, PROCESSING AND MICROSTRUCTURAL STABILITY WITH WASPALOY, U720/U720LI AND ALLOY 718) THESE MATERIALS SHOULD BE DESCRIBED AS SIMILAR, COMPARABLE OR ALTERNATIVE ALLOYS, RATHER THAN AS 'EQUIVALENT GRADES.' AD730 COMMON NAMES & TRADE NAMES THE FOLLOWING TERMINOLOGY MAY APPEAR IN INTERNATIONAL PURCHASING AND TECHNICAL SEARCHES: • AD730 • AD730 • AD730 • PARMANU DHATU NIGAM AD730 • AD 730 NICKEL ALLOY • AD730 NICKEL SUPERALLOY • AD730 NICKEL-BASED SUPERALLOY • AD730 HIGH-TEMPERATURE ALLOY • AD730 AEROSPACE ALLOY • NICR16CO9MO3W3TI3AL2 • AD730 TURBINE ALLOY • AD730 TURBINE DISC ALLOY • AD730 FORGED ALLOY • AD730 ROUND BAR THE REGISTERED/TRADEMARKED COMMERCIAL DESIGNATION AD730 BELONGS TO PARMANU DHATU NIGAM. AD730 NICKEL ALLOY ROUND BAR MANUFACTURING PROCESS MANUFACTURING HIGH-QUALITY AD730 ROUND BAR REQUIRES TIGHTLY CONTROLLED MELTING, SOLIDIFICATION, THERMOMECHANICAL PROCESSING AND HEAT TREATMENT. A TYPICAL INDUSTRIAL ROUTE CAN INVOLVE: RAW-MATERIAL SELECTION → VACUUM MELTING → SECONDARY REFINING/REMELTING → INGOT PRODUCTION → HOMOGENIZATION → HOT WORKING/FORGING → BAR ROLLING OR FORGING → HEAT TREATMENT → STRAIGHTENING → MACHINING → INSPECTION → TESTING → CERTIFICATION THE PRECISE PRODUCTION ROUTE DEPENDS ON THE REQUIRED PRODUCT FORM, DIAMETER, GRAIN STRUCTURE, MECHANICAL PROPERTIES AND CUSTOMER SPECIFICATION. 1) RAW MATERIAL SELECTION HIGH-PURITY NICKEL, CHROMIUM, COBALT, MOLYBDENUM, TUNGSTEN, TITANIUM, ALUMINUM, NIOBIUM AND OTHER CONTROLLED ADDITIONS ARE SELECTED ACCORDING TO THE REQUIRED AD730 CHEMISTRY. PARTICULAR ATTENTION IS GIVEN TO: • SULFUR • OXYGEN • NITROGEN • CARBON • BORON • ZIRCONIUM • TRACE ELEMENTS • METALLIC CLEANLINESS • RESIDUAL ELEMENTS FOR AEROSPACE AND TURBINE APPLICATIONS, CHEMISTRY CONTROL AND MELT CLEANLINESS ARE CRITICAL. 2) VACUUM INDUCTION MELTING NICKEL-BASED SUPERALLOYS SUCH AS AD730 REQUIRE CONTROLLED MELTING CONDITIONS. VACUUM INDUCTION MELTING (VIM) MAY BE USED TO ACHIEVE: • PRECISE ALLOY CHEMISTRY • REDUCED ATMOSPHERIC CONTAMINATION • CONTROLLED REACTIVE ELEMENTS • IMPROVED CLEANLINESS • CONSISTENT INGOT QUALITY THE INDUSTRIAL LITERATURE DESCRIBES AD730 AS A CAST-AND-WROUGHT ALLOY AND DOCUMENTS CONTROLLED INDUSTRIAL PROCESSING ROUTES. 3) SECONDARY REMELTING DEPENDING ON THE PRODUCT SPECIFICATION, FURTHER REFINING/REMELTING CAN BE EMPLOYED TO IMPROVE METALLURGICAL CLEANLINESS AND REDUCE SEGREGATION. POTENTIAL ROUTES INCLUDE: • VIM • ESR — ELECTROSLAG REMELTING • OTHER SPECIALIZED SECONDARY MELTING ROUTES THE EXACT MELT ROUTE SHOULD BE SPECIFIED BY THE APPLICABLE AD730 PRODUCT SPECIFICATION RATHER THAN ASSUMED FOR EVERY ROUND BAR. 4) INGOT HOMOGENIZATION AFTER SOLIDIFICATION, THE AD730 INGOT CAN EXHIBIT CHEMICAL SEGREGATION AND NON-UNIFORM MICROSTRUCTURAL FEATURES. CONTROLLED HOMOGENIZATION HELPS REDUCE COMPOSITIONAL GRADIENTS BEFORE THERMOMECHANICAL PROCESSING. THE OBJECTIVE IS TO CREATE A MORE SUITABLE STARTING STRUCTURE FOR SUBSEQUENT: • FORGING • ROLLING • RING ROLLING • BAR PRODUCTION 5) HOT FORGING OF AD730 ROUND BAR HOT FORGING IS A KEY MANUFACTURING OPERATION. AD730 HAS BEEN DEVELOPED WITH USEFUL HOT-WORKING CHARACTERISTICS COMPARED WITH SOME CONVENTIONAL HIGH-STRENGTH Γ′ NICKEL SUPERALLOYS. RESEARCH REPORTS THAT AD730 HAS BETTER HOT-FORGING ABILITY THAN WASPALOY AND ALLOY 720 AND CAN BE FORGED BELOW THE Γ′ SOLVUS TO OBTAIN A FINE-GRAIN STRUCTURE. POSSIBLE PROCESSING ROUTES INCLUDE: OPEN-DIE FORGING USED FOR LARGE SECTIONS AND BREAKDOWN OPERATIONS. CLOSED-DIE FORGING USED FOR NEAR-NET-SHAPE AEROSPACE AND TURBINE COMPONENTS. ROTARY FORGING USED FOR CONTROLLED REDUCTIONS AND SPECIALIZED GEOMETRIES. RING ROLLING USED FOR RING-SHAPED COMPONENTS. BAR FORGING USED TO PRODUCE ROUND STOCK FOR SUBSEQUENT MACHINING. 6) HOT ROLLING / BAR CONVERSION AFTER FORGING OR BILLET CONVERSION, AD730 MAY BE PROCESSED INTO ROUND BAR THROUGH CONTROLLED HOT-WORKING OPERATIONS. TYPICAL OBJECTIVES INCLUDE: • DIAMETER REDUCTION • GRAIN REFINEMENT • MICROSTRUCTURAL HOMOGENIZATION • IMPROVED MECHANICAL PROPERTIES • DIMENSIONAL CONTROL THE EXACT REDUCTION SCHEDULE IS HIGHLY DEPENDENT ON BILLET SIZE, FINAL DIAMETER AND REQUIRED GRAIN STRUCTURE. 7) HEAT TREATMENT OF AD730 HEAT TREATMENT IS ONE OF THE MOST IMPORTANT STAGES IN AD730 MANUFACTURING BECAUSE ITS MECHANICAL PROPERTIES ARE STRONGLY ASSOCIATED WITH ITS Γ′-STRENGTHENED MICROSTRUCTURE. PARMANU DHATU NIGAM LISTS A HEAT-TREATMENT CONDITION DESIGNATED H + V FOR AD730 AND REPORTS A PUBLISHED MECHANICAL RESULT OF APPROXIMATELY: UTS: 1580 N/MM² WITH: ELONGATION: 20% FOR THE CITED CONDITION. HOWEVER, THESE VALUES SHOULD NOT BE TREATED AS UNIVERSAL VALUES FOR EVERY DIAMETER, PRODUCT FORM OR HEAT-TREATMENT CONDITION. SUB-SOLVUS HEAT TREATMENT SUB-SOLVUS PROCESSING CAN BE USED TO MAINTAIN A RELATIVELY FINE GRAIN STRUCTURE WHILE DEVELOPING THE DESIRED PRECIPITATION-STRENGTHENED MICROSTRUCTURE. FINE-GRAIN STRUCTURES CAN BE ADVANTAGEOUS WHERE THE APPLICATION REQUIRES AN APPROPRIATE BALANCE OF: • TENSILE STRENGTH • FATIGUE RESISTANCE • DUCTILITY • CREEP RESISTANCE AD730 RESEARCH HAS SPECIFICALLY INVESTIGATED Γ′ PRECIPITATION AND RECRYSTALLIZATION DURING THERMOMECHANICAL PROCESSING. SUPERSOLVUS HEAT TREATMENT SUPERSOLVUS TREATMENT CAN PRODUCE A COARSER GRAIN STRUCTURE THAT MAY IMPROVE CREEP PERFORMANCE FOR CERTAIN HIGH-TEMPERATURE APPLICATIONS. PUBLISHED RESEARCH ON AD730 INVESTIGATED A 1120°C SUPERSOLVUS TREATMENT TO DEVELOP A HOMOGENEOUS COARSE-GRAIN MICROSTRUCTURE FOR IMPROVED CREEP PERFORMANCE IN POWER-GENERATION TURBINE-DISC APPLICATIONS. THEREFORE, AD730 ROUND BAR MAY BE SUPPLIED IN DIFFERENT MICROSTRUCTURAL CONDITIONS DEPENDING ON ITS INTENDED APPLICATION. AD730 MICROSTRUCTURE AD730 IS PRIMARILY A Γ/Γ′ STRENGTHENED NICKEL-BASED SUPERALLOY. THE Γ MATRIX PROVIDES THE CONTINUOUS NICKEL-RICH PHASE, WHILE Γ′ PRECIPITATES PROVIDE SIGNIFICANT STRENGTHENING AT ELEVATED TEMPERATURES. THE MICROSTRUCTURE MAY ALSO CONTAIN CARBIDE AND OTHER PHASES THAT INFLUENCE HIGH-TEMPERATURE STRENGTH AND STABILITY. RESEARCH HAS DOCUMENTED THE ROLE OF Γ′ PRECIPITATION AND CARBIDE-CONTAINING FEATURES IN AD730. MICROSTRUCTURAL CONTROL IS PARTICULARLY IMPORTANT FOR: • TURBINE DISCS • ROTATING COMPONENTS • FASTENERS • BLADES • HIGH-TEMPERATURE SHAFTS • AEROSPACE COMPONENTS AD730 MECHANICAL PROPERTIES THE EXACT MECHANICAL PROPERTIES DEPEND ON: • HEAT TREATMENT • FORGING REDUCTION • GRAIN SIZE • BAR DIAMETER • TEST TEMPERATURE • TEST DIRECTION • PRODUCT SPECIFICATION PARMANU DHATU NIGAM PUBLISHES A REPRESENTATIVE ULTIMATE TENSILE STRENGTH OF 1580 MPA AND ELONGATION OF 20% FOR ITS LISTED H + V CONDITION. PUBLISHED RESEARCH ADDITIONALLY REPORTS STRONG TENSILE, FATIGUE AND CREEP PERFORMANCE AT TEMPERATURES APPROACHING 750°C. HIGH-TEMPERATURE PROPERTIES OF AD730 AD730 WAS SPECIFICALLY DEVELOPED FOR APPLICATIONS REQUIRING PERFORMANCE IN APPROXIMATELY THE 700–750°C RANGE. ITS MAJOR CHARACTERISTICS INCLUDE: HIGH TENSILE STRENGTH SUITABLE FOR HIGHLY LOADED HOT-SECTION COMPONENTS. CREEP RESISTANCE IMPORTANT FOR COMPONENTS EXPOSED TO SUSTAINED HIGH TEMPERATURES AND STRESS. FATIGUE RESISTANCE IMPORTANT FOR ROTATING TURBINE COMPONENTS SUBJECTED TO CYCLIC LOADING. OXIDATION RESISTANCE THE CHROMIUM-CONTAINING CHEMISTRY PROVIDES USEFUL RESISTANCE TO OXIDATION AT ELEVATED TEMPERATURES. MICROSTRUCTURAL STABILITY PARMANU DHATU NIGAM REPORTS GOOD MICROSTRUCTURAL STABILITY UP TO APPROXIMATELY 750°C. AD730 ROUND BAR MACHINING AD730 IS A HIGH-STRENGTH NICKEL-BASED SUPERALLOY AND REQUIRES APPROPRIATE MACHINING PRACTICES. RECOMMENDED CONSIDERATIONS INCLUDE: • HIGHLY RIGID MACHINES • SECURE WORKHOLDING • SHARP TOOLING • CONTROLLED CUTTING PARAMETERS • POSITIVE CUTTING ACTION • ADEQUATE COOLANT • AVOIDANCE OF EXCESSIVE DWELL • PROPER CHIP EVACUATION PARMANU DHATU NIGAM NOTES THAT AD730 MACHINABILITY IS COMPARABLE TO OTHER REFRACTORY NICKEL-BASED SUPERALLOYS AND RECOMMENDS RIGID TOOLING; CERAMIC TOOLING CAN BE USED FOR ROUGH MACHINING, WHILE COATED OR UNCOATED CARBIDE TOOLS CAN BE USED FOR FINISHING. AD730 WELDING & JOINING AD730 CAN BE INVESTIGATED FOR SPECIALIZED JOINING PROCESSES, BUT WELDING AND JOINING PROCEDURES SHOULD BE QUALIFIED FOR THE SPECIFIC APPLICATION. RESEARCH HAS EXAMINED: • LINEAR FRICTION WELDING • DISSIMILAR JOINING • POST-WELD HEAT TREATMENT • ADDITIVE MANUFACTURING-RELATED JOINING PUBLISHED WORK REPORTS SUCCESSFUL LINEAR-FRICTION-WELDING INVESTIGATIONS ON AD730 AND EXAMINES THE RESULTING MICROSTRUCTURE AND MECHANICAL PROPERTIES. FOR AEROSPACE COMPONENTS, AN APPROVED WELDING/JOINING PROCEDURE AND APPLICABLE CUSTOMER SPECIFICATION SHOULD TAKE PRECEDENCE OVER GENERIC WELDING RECOMMENDATIONS. AD730 ROUND BAR SURFACE FINISHING DEPENDING ON THE APPLICATION, AD730 ROUND BAR MAY BE SUPPLIED AS: • HOT FORGED • HOT ROLLED • PEELED • GROUND • CENTERLESS GROUND • TURNED • POLISHED • MACHINED TYPICAL REQUIREMENTS CAN INCLUDE: BRIGHT SURFACE + TIGHT DIAMETER TOLERANCE + STRAIGHTNESS + CONTROLLED ROUGHNESS + ULTRASONIC INSPECTION. THE ACTUAL DELIVERY CONDITION SHOULD BE STATED ON THE PURCHASE ORDER. AD730 ROUND BAR INSPECTION & TESTING FOR CRITICAL AEROSPACE AND TURBINE APPLICATIONS, INSPECTION CAN INCLUDE: CHEMICAL ANALYSIS VERIFICATION OF ALLOY CHEMISTRY. TENSILE TESTING ROOM-TEMPERATURE AND/OR ELEVATED-TEMPERATURE TESTING. HARDNESS TESTING VERIFICATION OF HEAT-TREATMENT CONDITION. MICROSTRUCTURAL EXAMINATION EVALUATION OF GRAIN SIZE AND PRECIPITATE STRUCTURE. ULTRASONIC TESTING DETECTION OF INTERNAL DISCONTINUITIES. EDDY-CURRENT TESTING SURFACE/SUBSURFACE DEFECT DETECTION WHERE APPLICABLE. DIMENSIONAL INSPECTION CHECKING: • DIAMETER • OVALITY • STRAIGHTNESS • LENGTH • SURFACE ROUGHNESS NON-DESTRUCTIVE TESTING DEPENDING ON THE SPECIFICATION: • UT • EDDY CURRENT • LIQUID PENETRANT • MAGNETIC PARTICLE INSPECTION WHERE TECHNICALLY APPLICABLE AD730 APPLICABLE STANDARDS THIS DISTINCTION IS ESSENTIAL: AD730 IS AN ALLOY DESIGNATION, WHILE ASTM, AMS, ISO, EN AND OTHER STANDARDS MAY SPECIFY PRODUCT REQUIREMENTS, TESTING PROCEDURES OR DIMENSIONAL REQUIREMENTS. THERE IS NO JUSTIFICATION FOR AUTOMATICALLY CLAIMING THAT AD730 ROUND BAR CONFORMS TO EVERY ASTM/AMS/EN STANDARD. POTENTIAL STANDARDS FRAMEWORKS USED IN PROCUREMENT AND QUALITY CONTROL CAN INCLUDE: • ASTM — MATERIAL/PRODUCT AND TESTING STANDARDS WHERE APPLICABLE • AMS — AEROSPACE MATERIAL SPECIFICATIONS WHERE AN APPLICABLE SPECIFICATION EXISTS • EN — EUROPEAN STANDARDS • ISO — INTERNATIONAL QUALITY/TESTING STANDARDS • ASME — ENGINEERING/MATERIAL REQUIREMENTS WHERE APPLICABLE • DIN — GERMAN STANDARDS WHERE CONTRACTUALLY SPECIFIED THE EXACT STANDARD MUST BE STATED AGAINST THE SPECIFIC AD730 PRODUCT FORM AND CUSTOMER SPECIFICATION. AD730 VS WASPALOY AD730 IS FREQUENTLY COMPARED WITH WASPALOY BECAUSE BOTH ARE HIGH-TEMPERATURE NICKEL-BASED SUPERALLOYS. HOWEVER: AD730 ALLOY FAMILY: NI-BASED SUPERALLOY MAIN STRENGTHENING: Γ′ AD730 DESIGNATION: NICR16CO9MO3W3TI3AL2 UNS: NO UNIVERSAL AD730 UNS TEMPERATURE CAPABILITY: ~750°C DIRECT EQUIVALENT?: NO TYPICAL APPLICATIONS: TURBINE DISCS, BLADES, FASTENERS WASPALOY ALLOY FAMILY: NI-BASED SUPERALLOY MAIN STRENGTHENING: Γ′ AD730 DESIGNATION: NICR20CO13MO4TI3AL UNS N07001 TEMPERATURE CAPABILITY: HIGH-TEMPERATURE SERVICE DIRECT EQUIVALENT?: NO TYPICAL APPLICATIONS: TURBINE DISCS, ENGINE COMPONENTS PARMANU DHATU NIGAM SEPARATELY IDENTIFIES WASPALOY AS UNS N07001, DEMONSTRATING WHY THAT DESIGNATION SHOULD NOT BE INCORRECTLY TRANSFERRED TO AD730. AD730 VS UDIMET 720 UDIMET 720 / ALLOY 720 IS ANOTHER HIGH-STRENGTH Γ′ NICKEL SUPERALLOY COMMONLY DISCUSSED ALONGSIDE AD730.
