Corrosion resistance: 904L corrosion resistance is better than ordinary stainless steel in all kinds of phosphoric acid.In strong oxidation of nitric acid, 904L lower corrosion resistance compared to non-molybdenum high alloy steel; In the hydrochloric acid, 904L limited to the use of lower concentrations of 1-2%. In this concentration range. 904L corrosion resistance better than generic stainless steel. 904L with a high resistance to pitting, its crevice corrosion resistance are also very good Chloride solution. 904L high nickel content, reducing the corrosion rate in gap and insurface blemish. Ordinary austenitic stainless steel in the temperature higher than 60 ℃, maybe sensitive of the stress corrosion resistance in a rich chloride environment, by increasing the nickel content in stainless steel, can reduce this sensitivity. Due to the high content of nickel, 904L with high stress corrosion cracking capacity in chloride solution, the concentration hydroxid solution and rich sulfureted hydrogen environment.
