Type 430 (UNS S43000) is a ferritic rolled coil stainless steel that has resistance to oxidation up to 1500ºF along with good ductility and corrosion resistance. This alloy is also often polished for cosmetic applications.
410 flat rolled stainless steel is reserved for applications that require some corrosion resistance and high mechanical properties.
430 Stainless Steel Specifications:
ASTM A240 for annealed condition
