Stainless Steel Alloy 403 is a straight chromium stainless steel that demonstrates reasonable corrosion resistance, high mechanical characteristics, and offers heat resistance and a scaling temperature of about 1300掳F. 304 is corrosion and heat resistant martensitic stainless steel that offers a wide range of mechanical properties obtainable by appropriate heat treating. Easily hardened by oil, fan or air cooling and can be tempered at temperatures at 1350掳F (732掳C) to improve fracture toughness.
