iSteel manufactures and trades high quality products such as Stainless Steel 904L Flanges to its clients across the globe. We manufacture our products keeping in check the current market trends and demands. Our SS 904L Flanges are austenitic stainless steel products with low carbon content. Copper is added to these 904L SS Flanges to improve its resistance to strong reducing acids. Alloy 904L is also resistant to stress corrosion cracking and crevice corrosion as well. Our 904L Stainless Steel Slip-On Flanges are non-magnetic, offering properties such as excellent weld-ability, formability and toughness. These UNS N08904 Flanges are used in pressure vessels to close pipe tails, they are specifically designed to retain pressure in high pressure areas. Due to the resistance to strong acids such as sulphuric acids these Flanges have found applications in petrochemical plants and oil refineries. Our Stainless Steel 904L Flange products are super austenitic and prevent chloride stress corrosion cracking. These SS 904 Threaded Flanges bear oxidation and heat resistance as well. We offer all our products in customizable shapes and sizes to meet customer requirements. Our Flanges are available in various kinds such as SS 904L Slip-On Flanges, SS 904 L Orifice Flanges, SS 904LBlind Flanges, SS 304L Weld-Neck Flanges, SS 904L Spectacle-Blind Flanges, SS 904L Ring-Type Joint Flanges and more. We carry out different processes of quality to maintain international levels of production standards in our products.
