430 is one of the most widely used of the "non-hardenable" ferritic stainless steels. With nominal 16% chromium 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.
Automotive trim and molding, furnace combustion chambers, dishwashers, range hoods, gas burners on heating units, gutters, downspouts and flatware.
430 has excellent corrosion resistance, including high resistance to nitric acid as well as to sulfur gases and many organic and food acids. Because of its relatively high chromium content, the material provides good resistance to oxidation. Its maximum scaling temperature is 1500 °F (816 °C) for continuous service.
Type 430 is readily drawn and formed. Its drawing characteristics are similar to those of low-carbon steel. This ferritic class is generally considered weldable by common fusion and resistance techniques. Special consideration is required to avoid brittle weld fractures by controlling weld heat input.
