About 904L stainless steel plate:

There are three types of 904L stainless steel plates: hot-rolled stainless steel plates, cold-rolled stainless steel plates, and finish-rolled stainless steel plates. 904L super austenitic stainless steel is a low-carbon, high-nickel, molybdenum austenitic stainless and acid-resistant steel. It is a proprietary material imported from France H·S. It has good activation-passivation transformation ability, excellent corrosion resistance, good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, and phosphoric acid, and good corrosion resistance in neutral chloride-containing media It has good pitting corrosion resistance and good resistance to crevice corrosion and stress corrosion. It is suitable for sulfuric acid of various concentrations below 70°C, and has good corrosion resistance in acetic acid at any concentration and at any temperature and mixed acid of formic acid and acetic acid under normal pressure.

Super austenitic stainless steel 904L (00Cr20Ni25Mo4.5Cu, UNS: N08904, EN: 1.4539) is a highly alloyed austenitic stainless steel with very low carbon content. It has good corrosion resistance in dilute sulfuric acid and is specially designed for Designed for harsh environments with corrosive conditions. It has a high chromium content and sufficient nickel content. The addition of copper makes it highly resistant to acid, especially to chloride crevice corrosion and stress corrosion cracking. It is not easy to appear corrosion spots and cracks, and is resistant to spots. Slightly better corrosion ability than other steel grades, has good workability and weldability, and can be used for pressure vessels


  1) The cold-rolled product has good gloss and beautiful appearance;


  2) Due to the addition of Mo, it has excellent corrosion resistance, especially pitting corrosion resistance;


  3) Excellent high temperature strength.


  4) Excellent work hardening (weak magnetic properties after processing)


  5) The solid solution state is non-magnetic;


  6) Compared with 304 stainless steel, the price is higher.
