ASTM A312 seamless Stainless Steel Pipes
for general corrosive service
MAX STAINLESS STEEL manufacturing and supply seamless austenitic stainless steel pipes intended for high-temperature and general corrosive service.Grades 304H, 309H, 310H, 316H, 321H, 347H are intended for high-temperature service.Optional supplementary requirements are provided for pipe where a greater degree of testing is desired. There supplementary requirements call for additional tests to be made and, when desired, one or more of these may be specified in the order.
The standardized dimensions of Seamless Stainless Steel Pipe as shown in ANSI B36.19. These dimensions are also applicable to heavily cold worked pipe. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification.
Grades TP321 and TP321H have lower strength requirements for pipe manufactured by the seamless process in nominal wall thicknesses greater than 3/8 in. [9.5 mm].
