ASTM A270 covers grades of seamless, welded, and heavily cold worked austenitic and ferritic/austenitic stainless-steel sanitary tubing. Seamless tubes shall be manufactured by a process that does not involve welding at any stage. Welded tubes shall be made using an automated welding process with no addition of filler metal during the welding process. Heavily cold worked tubes shall be made by applying cold working of not less than 35% reduction of thickness of both wall and weld to a welded tube prior to the final anneal. No filler shall be used in making the weld.

All material shall be furnished in the heat-treated condition. A chemical analysis of either one length of flat-rolled stock or one tube shall be made for each heat. Each tube shall be subjected to mechanical tests like reverse flattening test, hydrostatic test or nondestructive electric test.

The following surface finishes may be specified: mill finish, mechanically polished surface finish, finish No. 80, finish No. 120, finish No. 180, finish No. 240, electropolished finish, and maximum roughness average surface finish. Longitudinally polished finish shall be performed on the inside surface only while a circumferential polished finish shall be done on either the inside surface, outside surface, or both.
