THE CURRENT ASTM B574-23 SPECIFICALLY INCLUDES UNS N06059 AND COVERS ROD/BAR PRODUCTS IN SPECIFIED DIMENSIONAL RANGES AND CONDITIONS. 2) ALLOY 59 INTERNATIONAL EQUIVALENT DESIGNATIONS ONE OF THE MOST IMPORTANT AND PROCUREMENT CONSIDERATIONS IS THAT THE SAME ALLOY CAN APPEAR UNDER DIFFERENT NATIONAL, STANDARDS-BASED AND COMMERCIAL DESIGNATIONS. COUNTRY / SYSTEM - ALLOY 59 DESIGNATION COMMERCIAL NAME: ALLOY 59 NICKEL ALLOY NAME: NICKEL ALLOY 59 UNS N06059 WERKSTOFF NO 2.4605 EN DESIGNATION: NICR23MO16AL DIN 2.4605 / NICR23MO16AL GERMAN COMMERCIAL DESIGNATION: NICROFER 5923 HMO VDM COMMERCIAL DESIGNATION: VDM ALLOY 59 BÖHLER DESIGNATION: BÖHLER L059 CHINA: NS3311 / H06059 VDTÜV: MATERIAL SHEET 505 ASTM BAR/ROD: ASTM B574 ASME BAR/ROD: ASME SB-574 ASTM FORGINGS: ASTM B564 ASME FORGINGS: ASME SB-564 ASTM PLATE/SHEET/STRIP: ASTM B575 ASME PLATE/SHEET/STRIP: ASME SB-575 NACE: MR0175 / ISO 15156, WHERE APPLICABLE VDM IDENTIFIES ALLOY 59 AS 2.4605/N06059, WHILE VOESTALPINE LISTS THE EN DESIGNATION AS NICR23MO16AL AND IDENTIFIES ASTM B574, ASTM B564 AND NACE MR0175/ISO 15156 AMONG APPLICABLE STANDARDS. THE CHINESE DESIGNATION NS3311/H06059 IS ALSO ASSOCIATED WITH N06059 AND GB/T 15007-2017 IN MATERIAL DATABASES. IMPORTANT TERMINOLOGY DISTINCTION THESE DESIGNATIONS SHOULD NOT AUTOMATICALLY BE TREATED AS INTERCHANGEABLE PRODUCT SPECIFICATIONS. A MATERIAL DESIGNATION ESTABLISHES THE ALLOY IDENTITY, WHILE THE PRODUCT SPECIFICATION ESTABLISHES REQUIREMENTS FOR MANUFACTURING, DIMENSIONS, TESTING, HEAT TREATMENT AND CERTIFICATION. 3) ALLOY 59 TRADE NAMES AND BRAND NAMES COMMON COMMERCIAL NAMES ENCOUNTERED IN INTERNATIONAL PURCHASING INCLUDE: NICROFER 5923 HMO NICROFER 5923 HMO IS A WELL-KNOWN COMMERCIAL DESIGNATION ASSOCIATED WITH ALLOY 59 / 2.4605 / N06059) VDM ALLOY 59 PARMANU DHATU NIGAM MARKETS THE ALLOY AS VDM ALLOY 59, IDENTIFYING IT AS 2.4605/N06059) BÖHLER L059 VOESTALPINE HIGH PERFORMANCE METALS IDENTIFIES BÖHLER L059 AS 2.4605/N06059) OTHER SEARCH TERMINOLOGY INDUSTRIAL BUYERS MAY ALSO SEARCH FOR: • ALLOY 59 • NICKEL ALLOY 59 • N06059 • UNS N06059 • 2.4605 • NICR23MO16AL • NICROFER 5923 HMO • VDM ALLOY 59 • BÖHLER L059 • NS3311 • H06059 THESE TERMS ARE USEFUL FOR INTERNATIONAL BECAUSE ENGINEERS FREQUENTLY SEARCH BY UNS NUMBER, WERKSTOFF NUMBER, EN DESIGNATION, COMMERCIAL NAME OR ASTM SPECIFICATION, RATHER THAN SIMPLY 'ALLOY 59.' 4) CHEMICAL COMPOSITION OF ALLOY 59 ALLOY 59 DERIVES MUCH OF ITS CORROSION RESISTANCE FROM ITS NICKEL-CHROMIUM-MOLYBDENUM CHEMISTRY COMBINED WITH EXCEPTIONALLY LOW CARBON AND SILICON. A REPRESENTATIVE ASTM B574-BASED CHEMISTRY IS: ELEMENT - COMPOSITION, WT.% NICKEL BALANCE CHROMIUM 22.0–24.0 MOLYBDENUM 15.0–16.5 IRON ≤1.50 ALUMINUM 0.10–0.40 COPPER ≤0.50 COBALT ≤0.30 MANGANESE ≤0.50 SILICON ≤0.10 CARBON ≤0.010 PHOSPHORUS ≤0.015 SULFUR ≤0.010 THE EXACT ACCEPTANCE LIMITS SHOULD ALWAYS BE TAKEN FROM THE EDITION OF THE PRODUCT SPECIFICATION STATED ON THE PURCHASE ORDER/MTC. VDM AND VOESTALPINE DATA LIKEWISE IDENTIFY APPROXIMATELY 22–24% CR, 15–16.5% MO, BALANCE NI AND VERY LOW C/SI. 5) WHY ALLOY 59 IS USED FOR CORROSIVE-SERVICE BARS ALLOY 59 COMBINES: • HIGH CHROMIUM CONTENT • HIGH MOLYBDENUM CONTENT • NICKEL-RICH MATRIX • VERY LOW CARBON • VERY LOW SILICON • GOOD RESISTANCE TO PITTING CORROSION • GOOD RESISTANCE TO CREVICE CORROSION • RESISTANCE TO STRESS-CORROSION CRACKING • RESISTANCE TO MINERAL ACIDS • GOOD WELDING CHARACTERISTICS • GOOD THERMAL STABILITY • VDM SPECIFICALLY DESCRIBES RESISTANCE IN OXIDIZING AND REDUCING ENVIRONMENTS AND STRONG RESISTANCE TO CHLORIDE-INDUCED PITTING AND CREVICE CORROSION AS IMPORTANT CHARACTERISTICS. THIS MAKES ALLOY 59 ATTRACTIVE FOR: • CHEMICAL PROCESSING EQUIPMENT • PHARMACEUTICAL PROCESS EQUIPMENT • PETROCHEMICAL PLANTS • FLUE-GAS DESULFURIZATION SYSTEMS • WASTE-INCINERATION EQUIPMENT • ACID COOLERS • HEAT EXCHANGERS • SCRUBBERS • SEAWATER EQUIPMENT • CHLORIDE-CONTAINING PROCESS SYSTEMS • ACETIC-ACID PROCESSING • GEOTHERMAL EQUIPMENT • OIL & GAS APPLICATIONS 6) ALLOY 59 BAR MANUFACTURING PROCESS THE MANUFACTURING OF A HIGH-QUALITY ALLOY 59 BAR STARTS LONG BEFORE MACHINING. THE METALLURGY OF MELTING, REFINING, HOMOGENIZATION, HOT WORKING AND SOLUTION ANNEALING DETERMINES THE FINAL MICROSTRUCTURE AND CORROSION PERFORMANCE. STEP 1 — SELECTION OF RAW MATERIALS THE PRODUCER BEGINS WITH CONTROLLED NICKEL, CHROMIUM, MOLYBDENUM AND OTHER ALLOYING ADDITIONS. BECAUSE ALLOY 59 IS PARTICULARLY SENSITIVE TO UNDESIRABLE CONTAMINATION AND INTERMETALLIC PRECIPITATION, RAW MATERIALS MUST BE SELECTED AND CONTROLLED CAREFULLY. THE MANUFACTURING OBJECTIVE IS TO ACHIEVE: LOW C + LOW SI + CONTROLLED CR + CONTROLLED MO + CLEAN NI-BASED MATRIX STEP 2 — VACUUM MELTING / PRIMARY MELTING HIGH-PERFORMANCE PRODUCERS CAN USE CONTROLLED MELTING ROUTES SUCH AS: VIM → ESR OR AN ALTERNATIVE CONTROLLED MELTING ROUTE FOLLOWED BY ESR. VOESTALPINE SPECIFICALLY LISTS VIM + ESR OR AIR-MELTED + ESR FOR BÖHLER L059) WHY ESR MATTERS ELECTROSLAG REMELTING CAN HELP IMPROVE: • CHEMICAL HOMOGENEITY • CLEANLINESS • INCLUSION CONTROL • INTERNAL QUALITY • SURFACE QUALITY • STRUCTURAL UNIFORMITY FOR CRITICAL CORROSION-RESISTANT NICKEL ALLOY PRODUCTS, INTERNAL QUALITY IS PARTICULARLY IMPORTANT. 7) ALLOY 59 BILLET AND BLOCK MANUFACTURING THE MOLTEN ALLOY IS CONVERTED INTO AN APPROPRIATE SEMI-FINISHED FORM. DEPENDING ON THE PRODUCER'S MANUFACTURING ROUTE, THIS MAY INVOLVE: MELTING → REFINING → CASTING → BILLET → HOMOGENIZATION → HOT WORKING A BILLET IS THEN USED AS THE STARTING STOCK FOR PRODUCING BARS AND OTHER LONG PRODUCTS. ALLOY 59 FORGED BLOCK LARGE ALLOY 59 BLOCKS OR FORGED BLANKS ARE GENERALLY PRODUCED THROUGH A FORGING ROUTE RATHER THAN SIMPLY TREATING THEM AS STANDARD ASTM B574 BAR. A TYPICAL ROUTE CAN BE: ALLOY MELTING → ESR → CAST BILLET/INGOT → REHEATING → OPEN-DIE FORGING → UPSETTING/DRAWING → SOLUTION ANNEALING → MACHINING → INSPECTION WHERE THE PURCHASED PRODUCT IS A FORGING, ASTM B564 / ASME SB-564 IS A RELEVANT SPECIFICATION FOR ALLOY 59 FORGINGS. ASTM B564 EXPLICITLY INCLUDES UNS N06059 AMONG COVERED LOW-CARBON NI-CR-MO ALLOYS. 8) ALLOY 59 ROUND BAR MANUFACTURING ALLOY 59 ROUND BAR IS ONE OF THE MOST COMMERCIALLY IMPORTANT FORMS. A REPRESENTATIVE PRODUCTION ROUTE IS: RAW MATERIALS → MELTING → ESR → BILLET → REHEATING → HOT FORGING/ROLLING → SOLUTION ANNEALING → DESCALING → STRAIGHTENING → GRINDING/TURNING → ULTRASONIC TESTING → DIMENSIONAL INSPECTION → MARKING → MTC ASTM B574-23 COVERS ALLOY N06059 RODS AND BARS AND SPECIFIES DIFFERENT PRODUCT/FINISH CONDITIONS ACCORDING TO DIMENSIONAL RANGES. IT INCLUDES SOLUTION-ANNEALED AND PICKLED/MECHANICALLY DESCALED PRODUCTS AND LARGER GROUND/TURNED PRODUCTS.

TYPICAL APPLICATIONS INCLUDE: • CHEMICAL PROCESSING MACHINERY • STRUCTURAL CORROSION-RESISTANT COMPONENTS • MACHINED PLATES/BLANKS • HEAT-EXCHANGER COMPONENTS • PUMP AND VALVE COMPONENTS • CUSTOM-ENGINEERED PARTS 12) ALLOY 59 FLAT BAR MANUFACTURING ALLOY 59 FLAT BAR MAY BE PRODUCED FROM FORGED/ROLLED STOCK AND SUBSEQUENTLY CUT AND FINISHED TO CUSTOMER DIMENSIONS. TYPICAL MANUFACTURING OPERATIONS INCLUDE: 1. BILLET PRODUCTION 2. REHEATING 3. HOT ROLLING OR FORGING 4. SOLUTION ANNEALING 5. DESCALING 6. STRAIGHTENING 7. SAW CUTTING 8. GRINDING 9. DIMENSIONAL INSPECTION FOR FLAT PRODUCTS SUCH AS PLATE, SHEET AND STRIP, ASTM B575 IS THE RELEVANT ASTM SPECIFICATION RATHER THAN B574) ASTM B575 EXPLICITLY COVERS UNS N06059 AMONG ITS LOW-CARBON NICKEL-CHROMIUM-MOLYBDENUM ALLOYS. THEREFORE, A PURCHASER SHOULD DISTINGUISH BETWEEN: ALLOY 59 FLAT BAR → BAR/FORGING SPECIFICATION AS APPLICABLE AND ALLOY 59 PLATE/SHEET/STRIP → ASTM B575 / ASME SB-575 WHERE SPECIFIED. 13) ALLOY 59 HOLLOW BAR MANUFACTURING ALLOY 59 HOLLOW BAR IS A SPECIALIZED PRODUCT. POSSIBLE MANUFACTURING ROUTES INCLUDE: • HOLLOW FORGING • PIERCING • EXTRUSION • MACHINING FROM SOLID BAR • TREPANNING • CUSTOM FORGED HOLLOW STOCK A TYPICAL ROUTE MAY BE: ALLOY 59 BILLET → REHEATING → PIERCING/FORGING → HOLLOW REDUCTION → SOLUTION ANNEALING → SIZING → MACHINING → NDT HOLLOW BAR SHOULD NOT AUTOMATICALLY BE CERTIFIED AS SEAMLESS PIPE MERELY BECAUSE IT HAS A HOLLOW GEOMETRY. FOR PRESSURE-CONTAINING TUBE/PIPE APPLICATIONS, THE APPROPRIATE ASTM/ASME PIPE OR TUBE SPECIFICATION MUST BE SPECIFIED SEPARATELY. 14) ALLOY 59 SOLUTION ANNEALING SOLUTION ANNEALING IS A CRITICAL PART OF ALLOY 59 MANUFACTURING. THE OBJECTIVE IS TO ESTABLISH A SUITABLE HOMOGENEOUS MICROSTRUCTURE AND DISSOLVE UNDESIRABLE PHASES FORMED DURING PRIOR THERMAL AND MECHANICAL PROCESSING. AFTER SOLUTION ANNEALING, THE PRODUCT MAY UNDERGO: • WATER QUENCHING • RAPID COOLING • PICKLING • MECHANICAL DESCALING • GRINDING • TURNING • STRAIGHTENING THE EXACT HEAT-TREATMENT TEMPERATURE, HOLDING TIME AND COOLING PROCEDURE SHOULD BE CONTROLLED ACCORDING TO THE APPLICABLE MATERIAL SPECIFICATION AND PRODUCER'S QUALIFIED MANUFACTURING PROCEDURE. 15) COLD WORKING OF ALLOY 59 BARS COLD WORKING CAN BE USED TO ACHIEVE: • IMPROVED DIMENSIONAL ACCURACY • BETTER SURFACE FINISH • INCREASED STRENGTH • CONTROLLED GEOMETRY • SMALLER DIAMETER BAR PRODUCTION ASTM B574 SPECIFICALLY RECOGNIZES COLD-FINISHED CONDITIONS FOR N06059 WITHIN ITS COVERED DIMENSIONAL RANGE. COLD-WORKED ALLOY 59 CAN HAVE SUBSTANTIALLY HIGHER STRENGTH THAN SOLUTION-ANNEALED MATERIAL, BUT INCREASED STRENGTH GENERALLY COMES WITH REDUCED DUCTILITY. THEREFORE, THE PURCHASE SPECIFICATION SHOULD IDENTIFY THE REQUIRED CONDITION RATHER THAN MERELY STATING 'ALLOY 59.' 16) ALLOY 59 BAR SURFACE FINISHING DEPENDING ON CUSTOMER REQUIREMENTS, ALLOY 59 BARS CAN RECEIVE: PICKLED FINISH REMOVES SCALE AND SURFACE OXIDES FOLLOWING HEAT TREATMENT. MECHANICALLY DESCALED FINISH USES CONTROLLED MECHANICAL PROCESSES TO REMOVE SCALE. GROUND FINISH PROVIDES IMPROVED DIMENSIONAL ACCURACY AND SURFACE QUALITY. TURNED FINISH USED FOR PRECISION DIMENSIONAL CONTROL. POLISHED FINISH USED WHEN ENHANCED SURFACE APPEARANCE AND LOW ROUGHNESS ARE REQUIRED. ASTM B574 SPECIFICALLY RECOGNIZES SOLUTION-ANNEALED, PICKLED/MECHANICALLY DESCALED AND GROUND/TURNED CONDITIONS FOR APPLICABLE N06059 ROD/BAR DIMENSIONS. 17) ALLOY 59 BAR INSPECTION AND TESTING A QUALITY ALLOY 59 BAR MANUFACTURING PROGRAM CAN INCLUDE: CHEMICAL ANALYSIS VERIFICATION OF: • NI • CR • MO • FE • AL • CO • CU • MN • SI • C • P • S MECHANICAL TESTING DEPENDING ON THE APPLICABLE SPECIFICATION: • TENSILE STRENGTH • YIELD STRENGTH • ELONGATION • HARDNESS ASTM B574 REQUIRES CHEMICAL AND MECHANICAL CONFORMITY FOR COVERED ROD/BAR PRODUCTS.
