ASTM A249 is a standard about Welded Austenitic Stainless Steel BoilerSuperheater, Heat-Exchanger, and Condenser pipes/tubes.

ASTM A249 standard covers nominal-wall-thickness welded stainless steel pipes/tubes and heavily cold worked welded stainless steel pipes/tubes made from the austenitic steels, with various grades intended for such use as boiler, superheater, heat exchanger, or condenser tubes.

According to ASTM A249, subsequent to welding and prior to final heat treatment, the stainless steel pipes/tubes shall be cold worked either in both weld and base metal or in weld metal only. The method of cold working may be specified by the purchaser. When cold drawn, the purchaser may specify the minimum amount of reduction in cross-sectional area or wall thickness, or both.

Being a professional manufacturer of welded stainless steel pipes/tubes, we product our pipes  in strict accordance with the requirements of the ASTM A249 standard, from material to finished pipes test.
