904L Stainless Steel Flanges are made up of a nickel-chromium austenitic stainless steel which has 23% nickel and 19% chromium minimum in the composition with carbon, manganese, silicon, phosphorus, sulfur, copper, and 4% molybdenum to it. Fitwel Industries LLP is a leading supplier and manufacturer of 904L Stainless Steel Flanges in various categories. The nickel-chromium-molybdenum composition provides the material with excellent corrosion resistance and strength. It also has good mechanical properties such as 220MPa minimum yield strength and 490MPa minimum tensile strength. The melting point of the material is also high at 1350 degrees Celsius. The Alloy 904L Slip On Flanges is used at the end of a pipe to close it, mostly permanently. The material is a low carbon version of the 904 grade of steel. This means welding and forming operations are easy on these flanges without risking grain formation and intergranular corrosion due to the carbide precipitation while welding.
