American Society for Testing and Materials (ASTM). Current edition approved March 1, 2006. Published March 2006. Originally approved in 1980. Last previous edition approved in 2002 as A 774/A 774M – 02. 4 p. This specification covers five grades of as-welded, wrought austenitic stainless steel fittings for low-pressure piping and intended for low and moderate temperatures and general corrosive service. Users should note that certain corrosive conditions may restrict the use of one or more grades. For applications requiring a product that requires heat treatment or full pressure rating, refer to Specification A 403/A 403M. The term fittings applies to butt and socket welding parts such as 45° and 90° elbows, tees, reducers, wyes, laterals, crosses, and stub ends.
