430 Stainless Steel 430F Stainless Steel S43000 1.4016 1.4104 Stainless Steel
430 Stainless Steel is a low-carbon plain chromium ferritic stainless steel. The steel has good corrosion resistance in mildly corrosive environments and good resistance to oxidation at elevated temperature. In the annealed condition the steel is ductile, does not harden excessively during cold work and can be formed using a large variety of roll forming or mild stretch-bending operations, as well as the more common drawing and bending processes.
430 Stainless Steel has limited weldability and should not be used in the as welded condition for dynamic or impact loaded structures. Being a ferritic material, 430 is liable to brittle fracture at sub-zero temperatures, and cannot be used in cryogenic applications. As the steel does not contain nickel or molybdenum, it is cheaper than any of the 300 series steel.
430 stainless steel is the most popular of all the straight chrome stainless steel. Its principal use is for decorative purposes. Because of its excellent heat and corrosion resistant properties, its ductility and because it costs less than the chrome-nickel grades, this Type 430 stainless steel is used in countless applications. These uses are primarily for stainless and decorative purposes including household appliances, metal molding, metal trim, cabinet hardware, hinges, drawn and formed parts and stampings.
