1. Different corrosion resistance
403 stainless steel contains 16% - 18% chromium, basically no nickel metal, while 304 stainless steel contains more chromium and nickel metals, so the corrosion resistance of 403 stainless steel is relatively poor.
2. Different stability

3. Different toughness
304 stainless steel has a strong toughness, which is weaker than 403 stainless steel, so 304 stainless steel has a stronger toughness than 403 stainless steel.
