Sachiya Steel International is one of the Leading Manufacture And Exporter of Stainless Steel 304 Buttweld Fittings, which is a molybdenum bearing austenitic stainless steel that provides improved corrosion resistance. These Stainless Steel 304 Tee Pipe Fittings is non – magnetic in the annealed condition but may become slightly magnetic as a result of welding. Stainless Steel 304 Stub End Pipe Fittings has excellent corrosion resistance in a wide range of chemicals, especially in acidic chloride environments such as those encountered in pulp and paper mills.
Increased levels of chromium, molybdenum and nickel in these Stainless Steel 304 End Cap, improve resistance to chloride pitting and general corrosion. Resistance of Stainless Steel 304 Dish Cap Pipe Fittings increases with molybdenum alloy content, which is further resistant to sulphuric acid concentrations up to 5 percent at temperatures as high as 120 Degree F (49 Degree C). At temperatures under 100 Degree F (38 Degree C), these Stainless Steel 304 Long Radius Elbow has excellent resistance to solutions of higher concentration.

However, service tests in Stainless Steel 304 Short Radius Elbow Pipe Fittings are recommended to account for the effects of specific operating conditions that may affect corrosion behavior. In processes where condensation of Sulphur – bearing gases occurs, these Stainless Steel 304 Elbow Pipe Fittings is much more resistant to attack at the point of condensation than conventional alloy 316.
