Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 904L Socket Weld Fittings, which is available at best prices to our clients. Stainless Steel 904L Forged Socket Weld Elbow is less resistant to nitric acid than grades 304L and 310L, which are free of molybdenum. Stainless Steel 904L Forged Socket Weld Tee offer good oxidation resistance, where most common fusion and resistance methods may be employed. However, the structural stability of Stainless Steel 904L Forged Socket Weld Cap collapses at high temperatures, particularly above 400 Degree C. Stainless Steel 904L Forged Socket Weld Coupling can be solution heat – treated at 1090 Degree C to 1175 Degree C, following by rapid cooling, where thermal treatment is suitable for hardening these grades.
Stainless Steel 904L Forged Socket Weld Cross needs to be solution treated following cold working, to achieve maximum stress corrosion cracking resistance under critical environments. Welding of Stainless Steel 904L Forged Socket Weld Union can be performed using all conventional methods, which further does not require pre – heat and post – weld heat treatments.
Stainless Steel 904L Forged Socket Weld Plug can be subjected to hot cracking in constrained weldment, which further can be readily bent to a small radius under cold conditions. Full annealing of Stainless Steel 904L Forged Socket Weld Lateral Tee should follow any hot work to re – attain maximum ductility and corrosion resistance.
