904L Stainless Steel Plate

904L Stainless steel plate is divided into: hot-rolled stainless steel plate, cold-rolled stainless steel plate, finishing stainless steel plate.


Classification

Super austenitic stainless steel (904L stainless steel plate) is a very low carbon content of high alloying austenitic stainless steel, in dilute sulfuric acid has a good corrosion resistance, designed for the harsh environment of corrosive conditions. With high chromium content and enough nickel content, the addition of copper makes it have strong acid resistance, especially for the corrosion of chloride clearance and stress corrosion cracking has a high resistance, not easy to appear erosion spots and cracks, pitting corrosion resistance slightly superior and other steel, with good processability and solderability, can be used for pressure vessels.
