ASME SA-213/SA-213M S30815 Material Machining Technology

Corrosion resistance is a measure of a material's ability to resist rust and other forms of oxidation. ASME SA-213/SA-213M S30815 steel has excellent corrosion resistance, thanks to its high alloy content. The chromium and nickel present in the alloy form a protective layer on the surface of the steel, protecting it from the elements. Other elements, such as molybdenum, silicon and phosphorus, also contribute to the alloy's corrosion resistance by increasing hardness and reducing porosity.
