302 Stainless Steel Wire
Type 302 stainless steel wire has a carbon content of up to 0.15%, is higher than 304, has a slightly lower chromium and nickel content, a chromium content of 17-19%, and a nickel content of 8-10%. Common forms are strip and line. It has corrosion resistance, is non-magnetic, is usually used in an annealed state, and has good formability.
