Stainless Steel 904L (UNS N08904) is a super austenitic stainless steel that is designed for moderate to high corrosion resistance in a wide range of process environments. The combination of high chromium and nickel content combined molybdenum and copper which assure good to excellent corrosion resistance.
We at K. K. industries carries a wide range of Alloy 904L inventory which comprises with pipes, tubes, bars & rods, fasteners, fittings and flanges, slip-on, blind, weld-neck, lap joint, long welding neck, socket weld, elbows, tees, stub-ends, returns, caps, crosses, reducers, and pipe nipples etc. in different sizes, dimensions and specifications.
With its highly alloyed chemistry – 25% nickel and 4.5% molybdenum, 904L provides good chloride stress corrosion cracking resistance, pitting and general corrosion resistance. Steel 904L was originally developed to withstand environments containing dilute sulfuric acid.
Werkstoff Nr. 1.4539 stainless steel finds a wide variety of applications like Chemical plant, oil refinery, petrochemical plants, pulp & paper industry, pharmaceuticals, oil & gas, combustion gas desulfurization plants and many more. Contact us today for more information!
