300 Series Stainless Steels
The 300 series stainless steels are the most common chrome-nickel steels that resist corrosion and are suitable for temperature extremes while maintaining strength and durability. Various alloying elements alter properties such as hardening, tensile strengths, ductility, elongation and formability. Molybdenum, copper, titanium, nickel and nitrogen are common alloying elements that alter usability service. You can get specific answers at no charge from a Shelmet metal casting expert Help Line.
