2B Surface DIN 1.4539 Sus904L Stainless Steel Plate Inox 904L Plate
904l Introduction:
Super austenitic stainless steel (904 l stainless steel plate) is a kind of low carbon, high alloy austenitic stainless steel, it has good corrosion resistance, specially designed for harsh environment corrosion conditions. With high content of chromium and nickel content enough, the addition of copper make it has strong acid resistance, especially for chloride clearance corrosion and stress corrosion cracking are highly resistant, not easy appeared pitting spots and cracks, pitting resistance slightly with other steel grade, has good weldability and workability, can be used for pressure vessels.
