Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality Stainless Steel 304 Hydraulic Fittings, which are a molybdenum bearing and low carbon contents austenitic stainless steel that provides improved corrosion resistance over 304l and 316l stainless steels. The low carbon in our Stainless Steel 304 Forged Hydraulic Fittings provides resistance to sensitization during welding and other thermal processes. These Stainless Steel 304 Hydraulic Type Fittings has slightly improved corrosion resistance over type 321 stainless steel in strongly oxidizing environments. SS 304 Hydraulic Fittings are non – magnetic in the annealed condition but may become slightly magnetic as a result of welding.
These Grade 304 Hydraulic 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. Type 304 Hydraulic Fittings is resistant to sulphuric acid concentrations at temperatures as high as 120 Degree f (49 Degree c) at temperatures under 100 Degree f (38 Degree c) this alloy has excellent resistance to solutions of higher concentration.
These 304 Stainless Steel Hydraulic Fittings offers higher creep and stress rupture properties, particularly which might also be considered for exposures where sensitization and inter – granular corrosion are concerns. UNS S30400 Hydraulic Fittings has a columbium (niobium) / tantalum stabilized austenitic chromium – nickel stainless steel which was developed to provide an 18 – 8 type alloy with improved inter – granular – corrosion resistance.
