For stainless steel pressure vessels, when designing according to ASME VIII – Ⅰ, the commonly used material standards for plates, pipes, forgings, bolts, and nuts can be found in ASME II Part A, mainly including the following:

stainless steel pressure vessels

1.Board:

SA-240/SA-240M Specification for Chromium and Chromium Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications》

For example: SA-240/SA-240M 304/304L/316/316L

2.Pipe material:

SA-312/SA-312M “Specification for Seamless, Welded, and Heavily Cold Worked Austenitic

Stainless Steel Pipes》

For example: SA-312/SA-312M TP304/TP304L/TP316/TP316L

3.Forged parts

SA-182/SA-182M Specification for Forged or Rolled Alloy and Stainless Steel Pipe Flanges,

Forged Fittings, and Valves and Parts for High-Temperature Service》

For example: SA-182/SA-182M F304/F 304L/F 316/F 316L

4.Bolt

SA-193/SA-193M “Specification for Alloy Steel and Stainless Steel Bolting for High Pressure Service and Other Special Purpose Applications”

For example: SA-193/SA-193M B8/B8M

5.Nut

SA-194/SA-194M “Specification for Carbon and Alloy Steel Nuts for Bolts for High Pressure or High Temperature Service, or Both”

For example: SA-193/SA-193M 8/8M
