630 stainless steel is precipitated, quenched, martensitic stainless steel, and this grade offers properties such as high strength, hardness and corrosion resistance. After heat treatment, the mechanical properties of the product are more perfect, and the compressive strength can reach up to 1100-1300 mpa (160-190 kSi). This grade is not intended for use above 300℃ (570F) or very low temperatures. It has good corrosion resistance to atmospheric and diluted acids or salts, as is the case with 304 and 430.
