What is the difference between stainless steel of 403 and 304
Apr 19,2023
1. The corrosion resistance is different
, 403 stainless steel contains 16%-18% chromium, and basically does not contain nickel metal, while 304 stainless steel contains more chromium and nickel metal, so the corrosion resistance of 403 stainless steel is relatively poor.
2. The stability performance is different
, 403 stainless steel is ferritic form, 304 is austenitic form, so 304 stainless steel is more stable than 403 stainless steel.
3. The toughness is different
, 304 stainless steel has strong toughness, and the toughness is weaker than 403 stainless steel, so 304 stainless steel has stronger toughness than 403 stainless steel.
