Grade 630 stainless steels are martensitic stainless steels that are precipitation hardened to achieve excellent mechanical properties. These steel achieve high strength and hardness following heat treatment. Like all of the products sold by Continental Steel, our Type 630 Stainless Steel meets critical industry standards like ASTM A564.
