Sachiya Steel International is one of the leading Manufacturer and Exporter of Stainless Steel 321 Socket Weld Fittings, which is readily welded by most standard processes. Stainless Steel 321 Forged Socket Weld Fitting should be considered for applications requiring intermittent heating between 800 º F (427 º C) and 1650 º F (899 º C). In welded ambient temperature applications, Stainless Steel 321H Forged Socket Weld Fittings has been replaced by SS 304L. Stainless Steel 321 Forged Socket Weld Elbow Fittings has excellent resistance to inter-granular corrosion and has excellent weldability.
Stainless Steel 321 Forged Socket Weld Tee Fitting has excellent corrosion resistance at normal temperatures but is primarily designed to perform at elevated temperatures. Austenitic class of Stainless Steel 321 Forged Socket Weld Cap Fitting is generally considered to be weldable by the common fusion and resistance techniques. Stainless Steel 321 Forged Socket Weld Coupling Fittings is often used for aircraft piston engine manifolds and exhaust stacks.
Typical applications of Stainless Steel 321 Forged Socket Weld Cross Fitting include Aircraft exhaust manifolds and Expansion joints. Stainless Steel 321 Forged Socket Weld Union Fittings is extremely beneficial in applications of temperatures ranging from 800 ° F, to 1600 ° F, as it eliminates the necessity for re-annealing after fabrication. These Stainless Steel 321 Forged Socket Weld Plug Fittings is also used in Weld equipment and Chemical processing equipment.
