This specification covers spray-formed seamless austenitic stainless steel pipe intended for high-temperature and general corrosive service. The steel shall conform to the specified chemical composition and tensile requirements. The mechanical test requirement includes, transverse or longitudinal tension test, flattening test, hydrostatic test and grain size determination are presented. One tension tests shall be made on a specimen for lots of more than 100 pipes. For material heat treated in a batch-typed furnace, flattening tests shall be made on 5% of the pipe from each heat treated lot. Each length of finished pipe shall be subjected to hydrostatic tests.
