420 hot rolled/cold rolled stainless steel coil
AISI Type 420 is a martensitic stainless steel that provides increased strength and hardness relative to Type 410, with moderate corrosion resistance. It is magnetic in both the annealed and hardened conditions. Maximum corrosion resistance is attained in the fully hardened or fully hardened and stress relieved condition. High carbon content results in the formation of chromium carbide compounds, providing excellent wear resistance and edge retention when hardened. The alloy is not normally used at temperatures exceeding 800°F (427°C) due to rapid softening and loss of corrosion resistance.
