Anotace

This specification covers straight seam and spiral butt seam welded unannealed austenitic stainless steel tubular products intended for low and moderate temperatures and corrosive service where treatment is not necessary for corrosion resistance. The tubular products shall be made from flat-rolled steel sheet, coil, or plate by a shielded arc-welding process. The welds shall be made by the manual or automatic electric-welding process. Injurious weld defects shall be repaired by removal to sound metal and rewelding. Transverse tension test and transverse-guided bend test shall be done to the welded joints. Finished products shall have smooth ends free or burrs and shall be free of injurious defects.
