Contact form
Alloy 420 is a premium-grade hardenable, martensitic stainless steel - an enhanced variant of Alloy 410. With its higher carbon content, 420 Mirror Stainless Steel Sheet delivers superior strength and hardness characteristics. While maintaining excellent malleability in the hardened state, it can achieve an impressive Rockwell hardness of up to 50 HRC - the highest among 12% chromium grades. The mirror finish provides exceptional aesthetic appeal and corrosion resistance, making it ideal for decorative applications.
