904l Stainless Steel Plate Astm A240 Standard 8*1500*6000MM SS 904L Chemical Composition
ASTM SAE AISI 904L Stainless Steel (UNS N08904)
AISI 904L stainless steel (UNS N08904) is a high alloy austenitic stainless steel. Compared with 316L, SS904L has lower carbon (C) content, higher chromium (Cr) content, and approximatively twice the nickel (Ni) and molybdenum (Mo) content of 316L, which makes it have higher high temperature oxidation resistance, pitting resistance, and resistance to reducing acid (eg, sulfuric acid). Nitrogen (N) can reduce the rate of chromium carbide precipitation, thereby reducing the sensitivity of sensitization, it also improve the resistance to pitting and crevice corrosion caused by chlorides. Especially its addition of copper (Cu) makes it useful for all concentrations of sulfuric acid.

Product process:
According to the microstructure characteristics of steel grades, it can be divided into 5 types: austenite type, austenite-ferrite type, ferrite type, Martensite type and precipitate hardening type. Requirements can withstand oxalic acid, sulfuric acid-ferric sulfate, nitric acid, nitric acid-hydrofluoric acid, sulfuric acid-copper sulfate, phosphoric acid, formic acid, acetic acid and other acids corrosion, widely used in chemical industry, food, medicine, paper making, petroleum, atomic energy and other industries, as well as construction, kitchenware, tableware, vehicles, household appliances and various parts.
The characteristics of 904L stainless steel sheet:
1) Cold rolled products have good gloss and beautiful appearance;
2) Excellent corrosion resistance, especially pitting resistance, due to the addition of Mo;
3) Excellent high temperature strength
4) Excellent work hardening (weak magnetic after processing)
5) No magnetism in solution state;
