Product Description


High strength stainless steel SUS 630 UNS S17400  is precipitated, quenched, martensitic stainless steel, and this grade has high  strength, hardness and corrosion resistance characteristics. After heat  treatment, the mechanical properties of the products are improved, and the  pressure strength can reach up to 1100-1300 mpa (160-190 ksi).
