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).
This level cannot be used for higher than 300 ℃ (570 f) or very low temperatures, in the atmosphere and dilute acid or its salt has good corrosion resistance, it has the corrosion resistance of 304 and 430.
