420 Stainless Steel is a martensitic stainless steel that has similar corrosion resistance to 410. In addition, it has increased strength and hardness. 420 is magnetic in both hardened and annealed conditions. In order to attain maximum corrosion resistance 420 must be fully hardened and stress relieved.
