Sachiya Steel International is one of the pioneer trading house and dealer of Stainless Steel 304L Flanges, which is a molybdenum bearing and low carbon content “l” grade austenitic stainless steel that provides improved corrosion resistance. The low carbon in Stainless Steel 304L Slip On Flanges provides resistance to sensitization during welding and other thermal processes.

Stainless Steel 304L Threaded Flanges is non – magnetic in the annealed condition but may become slightly magnetic as a result of welding. Stainless Steel 304L Weld Neck Flanges have excellent corrosion resistance in a wide range of chemicals, especially in acidic chloride environments such as those encountered in pulp and paper mills.

Stainless Steel 304L Blind Flanges is resistant to sulphuric acid concentrations up to five percent at temperatures as high as 120 Degree f (49 Degree c) at temperatures under 100 Degree f (38 Degree c). Stainless Steel UNS S30403 Socket Weld Flanges has excellent resistance to solutions of higher concentration.

Stainless Steel 304L Lap Joint Flanges are slightly improved corrosion resistance over other alloys of stainless steel in strongly oxidizing environments as a result of the addition of columbium (niobium) and tantalum. Stainless Steel 304L Ring Joint Type Flanges does not perform well in chloride solutions, even in small concentrations, or in sulphuric acid.

The machinability of Stainless Steel 304L Spectacle Blind Flanges is difficult as it work-hardens during machining. The conventional machining techniques used on iron alloys may be used for Stainless Steel 304L Nippo Flanges
