630 Stainless SteelMartensitic precipitation hardening stainless steelThe 630 stainless steel's performance feature is its ease of adjusting the strength level, which can be modified by altering the heat treatment process.Martensitic transformationAndTime-sensitive processingFormulatePrecipitation HardeningPhosphating is its main strengthening method; 630 stainless steel features excellent attenuation properties, strong resistance to corrosion fatigue, and excellent滴水 resistance.

630 Stainless SteelIt is precipitated, hardened, and martensitic stainless steel.

630 Stainless SteelA precipitation-hardened, martensitic stainless steel composed of copper, niobium/tantalum.

This grade features high strength, hardness (up to 300°C/572°F), and corrosion resistance.

After heat treatment, the product's mechanical properties are further enhanced, achieving a tensile strength of up to 1100-1300 MPa (160-190 ksi).

This grade is not suitable for temperatures above 300°C (572°F) or extremely low temperatures. It exhibits excellent corrosion resistance to the atmosphere, as well as to diluted acids or salts, with corrosion resistance comparable to that of 304 and 430 grades.
