ASTM A249 Stainless Steel Tube




ASTM A249 Tube Manufacturer in India,ASTM A249 Stainless Tubes Supplier

Superior Steel Overseas is well known manufacturer, supplier, exporter and distributor of ASTM A249 Material.We are also largest stockholder of ASTM A249 Stainless Steel Welded Tube in customized size & standard at best price in India.We supply these ASME SA249 / ASTM A249 Grades are 201,202,304, 304L,305,310, 310s, 316, 316L, 317, 317L,321,  347, 410,446.ASTM A249 specification covers nominal-wall-thickness welded tubes and heavily cold worked welded tubes made from the austenitic steels. More specifically, the ASTM A249 specification is intended for uses such as boiler,superheater,heat exchanger,condenser tubes.ASTM A249-annealing of the tube is normally done in a controlled atmosphere and this “bright annealed” finish is considered acceptable.ASTM A249 Tube requires that at least the weld be cold worked after welding and before final heat treatment.ASTM A249 Welded Tube is intended for critical environments in boilers or heat exchangers, and hence extensive mechanical testing is required. Full tensile and hardness testing is standard, as are flattening, flange and reverse bend. ASTM A249 is written for a quite different application area. It does specify weld bead removal, but this requirement can be met from other standards, without unnecessarily calling up the stringent mechanical properties of A249. The annealing mandatory in A249 will also not be required in most food applications. A high cost option.
