Stainless Steel 904L Blind Flanges are a combination of nickel and molybdenum with the addition of low copper with iron for immensely expanded imperviousness to diminishing acids like sulphuric corrosive. It stands up to a great degree well to chlorides in the earth for low pitting and crevice corrosion, as well as stress corrosion cracking. The copper is added to the Flanges material to improve its resistance to strong reducing acids, such as sulphuric acid. The Flanges is non-magnetic, and it offers excellent toughness, formability, and weldability. It provides good resistance to oxidation.  The high resistance of stainless steel 904L Flanges against stress related corrosion cracking is due to the presence of high content of nickel in its composition. Moreover, the addition of copper to the Flanges material specification develops its resistance to sulphuric acid and other reducing agents in both aggressive and mild environmental conditions. These Stainless Steel 904L Flanges are extensively brought up into some common applications such as Pulp and Paper Industry, Heat exchangers, Condensers, Chemical equipment, Seawater equipment, Pharmaceutical equipment, and others. They are widely used in Chemical properties, the oil and gas industry, natural gas construction, petrochemical.
