This specification covers spray-formed seamless ferritic/austenitic stainless steel pipe intended for general corrosive service, with particular emphasis on resistance to stress corrosion cracking. These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures. The steel shall be made by the electric-furnace process and the pipe shall be made by the spray forming process using the melt from the primary melting. The as spray formed tubes shall be machined on both the inner and outer surfaces. All pipes shall be furnished in the heat-treated and descaled conditions. These pipes shall be free of contaminating iron particles. The specimens shall undergo transverse or longitudinal tension test, flattening test and hydrostatic test.
