Information about 904L stainless steel bolts and hex nuts
904L stainless steel bolts and hex nuts are highly corrosion-resistant fasteners, prized for their ability to withstand harsh environments, particularly strong acids and chlorides. They are a low-carbon, austenitic stainless steel with high nickel, chromium, and molybdenum contents, resulting in excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.
Which is better, 904L or 316L?
Corrosion resistance: 904L stainless steel offers superior corrosion resistance compared to 316L, especially in acidic environments. It is particularly adept at handling sulfuric acid, phosphoric acid, and chlorides.
