Product Details
Properties Of 904 904L Stainless Steel Plate :
---a good change activation-deactivation capabilities, excellent corrosion resistance, non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, phosphoric acid and has good corrosion resistance, in the neutral medium containing chloride ions has a good resistance to pitting, has a good resistance to crevice corrosion and stress corrosion performance.
·
·
---Applies to 70 ℃ the following kinds of concentrated sulfuric acid at atmospheric pressure under any concentration, temperature of acetic acid and formic acid and acetic acid corrosion resistance is also very good.
