The same logic applies to any other ASTM material grade listed in the table.
The piping ASTM materials match chart shows, for example, that an A106 Gr. A pipe matches with ASTM A234 buttweld fitting , with an ASTM A105 forged fitting, flange or valve, with an A216 WCB cast valve and with ASTM A193 B7 stud bolts .
The piping material chart shows the matching ASTM materials for pipes, valves, fittings, flanges and stud bolts.
COMMON ASTM MATERIALS FOR PIPING
STEEL PIPE MATERIALS
- ASTM A53 (Gr. A and B): seamless and welded carbon steel pipes for medium-high temperature and structural application
- ASTM A106 (Gr. A and B): Specification for seamless carbon steel pipe for high-temperature service
- ASTM A333 (Gr 1-11): Specification for seamless and welded pipes for low-temperature service
- ASTM A335 (Gr. P1 to P92): Specification for seamless ferritic alloy-steel pipe for high-temperature service
- ASTM A312 (TP 304, 316, 321, 347, etc): Standard specification for seamless, straight-seam welded, and cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service
- ASTM A790: Specification for seamless duplex and super duplex pipes (UNS S32205/31803 and UNS S32750/32760)
CAST VALVE MATERIALS
Cast valves feature a cast steel outer body:
- ASTM A216 (WCA, WBC, WCC): Specification for carbon steel castings for valves, flanges, fittings, or other pressure-containing parts for high-temperature service and of the quality suitable for assembly with other castings or wrought steel parts by fusion welding
- ASTM A217: Specification for steel castings, martensitic stainless steel and alloys steel castings for valves, flanges, fittings, and other pressure-containing parts intended primarily for high-temperature and corrosive service.
- ASTM A351 (CF8, CF8M): Specification for steel castings for Valves, flanges, fittings, and other pressure-containing parts intended primarily for low-temperature service
FORGED PIPING MATERIALS
This category includes the common materials used for socket weld and threaded fittings ASME B16.11 (forged fittings), valves with forged bodies (example API 602 / BS 5351 and BS 5352 valves), and steel flanges ASME B16.5.
- ASTM A105: Specification for standards for forged carbon steel piping components, that is, flanges, fittings, Valves, and similar parts, for use in pressure systems at ambient and higher-temperature service conditions
- ASTM A182: This specification covers forged or rolled alloy and stainless steel pipe flanges, forged fittings, and Valves and parts for high-temperature service.
- ASTM A350: Specification for several grades of carbon and low alloy steel forged or ring-rolled flanges, forged fittings and Valves for low-temperature service.
The chemical composition, mechanical properties and selection criteria for forged piping materials are analyzed in detail on this article.
BUTTWELD FITTINGS MATERIALS
- ASTM A234 (WPA, WPB, WPC): Specification for wrought carbon steel and alloy steel fittings of seamless and welded construction.
- ASTM A420: Standard specification for piping fittings of wrought carbon steel and alloy steel for low-temperature service.
- ASTM A403: Standard specification for wrought austenitic stainless steel piping fittings.
STUD BOLTS MATERIALS
- ASTM A193: Standard specification for alloy and stainless steel stud bolts materials for pressure vessels, valves, flanges, and fittings for high temperature or high pressure service, or other special purpose applications.
- ASTM A320: Standard Specification for Alloy-Steel and Stainless Steel Bolting Materials for Low-Temperature Service.
- ASTM A194: Standard specification for hexagonal steel nuts materials to match A193 and A320 stud bolts (threaded rod)
