⇒Characteristics of 904L N08904  

1.It has good corrosion resistance

2.Excellent corrosion resistance

Short Destription:

904L super austenitic stainless steel is a low carbon, high nickel, molybdenum austenitic stainless steel, which is the proprietary material of H·S Company in France. It has good activation-passivation transition ability, excellent corrosion resistance, good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, phosphoric acid, good pitting resistance in neutral chlorine-containing media, and good crevice corrosion resistance and stress corrosion resistance. It is suitable for sulfuric acid of various concentrations below 70℃, and corrosion resistance of acetic acid and mixed acid of formic acid and acetic acid at any concentration and temperature under normal pressure is also very good.
