The difference between ASTM A269 steel pipe and ASTM A249 stainless steel pipes

　　The differences between ASTM A269 stainless steel pipe and ASTM A249 steel pipe are as follows:

　　ASTM A269 - Seamless and welded austenitic stainless steel pipes for general equipment. This standard is universal for both stainless steel seamless pipes and stainless steel welded pipes. It is generally used in bright pipes and coiled pipes, and stainless steel welded pipes are commonly used. This is also the standard.

　　ASTM A249/A249M-2018_Welded austenitic steel welded pipes for boilers, superheaters, heat exchangers and condensers. This standard is an export standard for stainless steel welded pipes used on pressure pipes.
