430 Stainless Steel Sheet
430 stainless steel is one of the most widely used of the non-hardenable ferritic stainless steels. With nominal 16% chromium(Cr). it combines good corrosion resistance and heat and oxidation resistance up to 1500 °F (816 °C) with good mechanical properties. Type 430 is a non-stabilized stainless steel and as such is not suitable for all welded applications.

Type 430 has excellent corrosion resistance, including high resistance to nitric acid as well as to sulfur gases and many organic and food acids. This alloy does not provide the resistance to pitting by dilute reducing acids that is provided by the chromium-nickel stainless steels.
