630 Stainless SteelIt is a precipitation-hardened, quenching water, and martensitic stainless steel, with high strength, hardness, and corrosion resistance. After heat treatment, the product's mechanical properties are further enhanced, achieving a pressure resistance of up to 1100-1300 MPa (160-190 ksi). This grade is not suitable for temperatures above 300℃ (570°F) or extremely low temperatures. It exhibits excellent corrosion resistance against atmospheric conditions and diluted acids or salts, with corrosion resistance similar to 304 and 430 grades.
