Product Details
Alloy 904L (UNS N08904)W. Nr. 1.4539
Alloy 904L (UNS N08904) is a superaustenitic 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, coupled with additions of molybdenum and copper, assure good to excellent corrosion resistance.
With its highly alloyed chemistry — 25% nickel and 4.5% molybdenum, 904L provides good chloride stress corrosion cracking resistance, pitting and general corrosion resistance superior to 316L and 317L molybdenum enhanced stainless steels.
Alloy 904L was originally developed to withstand environments
containing dilute sulfuric acid. It also offers good resistance to
other inorganic acids such as hot phosphoric acid as well as most
organic acids.
Alloy 904L is easily welded and processed by standard shop
fabrication practices.
Product Forms : Sheet, plate , Coil , Strip .wire , Pipe, Tube ,Bar
, Profile, Round, Flat, Square, Hexagonal
