X5CrNiCuNb16-4 Martensite stainless steel

Martensite stainless steel X5CrNiCuNb16-4

X5CrNiCuNb16-4 stainless steel equal material : ASTM A693 grade 630 ,AMS 5604B, UNS S17400, 1.4542 , X5CrNiCuNb 16-4

X5CrNiCuNb16-4 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 corrosion resistance to atmospheric and dilute acid or Yandu, corrosion resistance and its 304 and 430.
