Molybdenum austenitic stainless steel X2CrNiMo18-15-4
X2CrNiMo18-15-4 equal material :00Cr19Ni13Mo3, SUSX2CrNiMo18-15-4 , 317L, 1.4438,UNS S31703.
X2CrNiMo18-15-4 is the basis of molybdenum austenitic stainless steel. It is with the conventional chromium - nickel austenitic stainless steel as compared with 304 alloy, corrosion resistant ability. In addition, compared with the conventional stainless steel, X2CrNiMo18-15-4 alloy has higher ductility, resistance to stress corrosion properties, compressive strength and high temperature performance. It is a low-carbon level or L level, this level has anti sensitization performance in welding and heat treatment during the process of.
