904 super austenitic stainless steel, low carbon and high town, giant austenitic stainless steel, is a proprietary material imported from French H.S. It has good activation and transformation ability, excellent corrosion resistance, good corrosion resistance in non-oxidizing acids sulfuric acid, acetic acid, formic acid and phosphoric acid, and good corrosion resistance in neutral chloride ion medium. It has excellent pitting corrosion resistance, good crevice corrosion resistance and stress corrosion resistance. It is suitable for sulfuric acid of various concentrations below 70C, acetic acid of any concentration and temperature under normal pressure, and resistance to mixed acids of formic acid and acetic acid. Corrosion resistance is also very good.

The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat,rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:
Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
During the hot rolling process,the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
