Martensite stainless steel S17400

Martensite stainless steel S17400

S17400 stainless steel equal material : ASTM A693, grade 630 ,AMS 5604B, UNS S17400, 1.4542 , X5CrNiCuNb 16-4
S17400 is precipitation, quenching, martensite stainless steel, and this level has high strength, hardness (up to 3000 C/5000 C) and corrosion resistance and other characteristics. After heat treatment, the mechanical properties of the products more perfect, can reach as high as 1100-1300 MPa (160-190 Ksi) compressive strength. This class cannot be used for more than 300 0C (572 0F) or very low temperatures, it has good corrosionresistance to atmospheric and dilute acid or Yandu, corrosion resistance and its 304 and 430.
