We firmly believe in contributing to an enterprise's progress, not only as a provider of goods and services but as a partner in building a strong and booming business. We, Fitwel Industries LLP undertake several strategies and implement them through transporting processes that add to the value of the business. We are a manufacturer, supplier, and exporter of Stainless Steel 904L Flanges that are a quality product from us supplied to you through strong logistical support and with no delay in shipment of the consignment. Our UNS N08904 Stainless Steel Blind Flanges are widely used to close the tail of the pipe of a pressure vessel, as they are designed to retain pressure in a high-pressure area, and are resistant to reducing acids like sulphuric acids in petrochemical plants and oil refineries. Our ASTM B649 Stainless Steel Lap Joint Flanges are super austenitic flanges, resistant to chloride stress corrosion cracking. They are a cost-effective alternative to transport acidic slurries. These SS 904L Threaded Flanges are oxidation and heat resistant. Also, We offer a wide range of Stainless Steel ASTM B649 904L Flanges such as SS 904L Slip On Flanges, SS 904L Weld Neck Flanges, SS 904L Socket Weld Flanges, SS 904L Blind Flanges, SS 904L Orifice Flanges, SS 904L Spectacle Blind Flanges, SS 904L Screwed / Threaded Flanges, SS 904L Reducing Flanges, SS 904L Ring Type Joint Flanges (RTJ), etc.
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.
