Molybdenum austenitic stainless steel 1.4438
1.4438 equal material :00Cr19Ni13Mo3, SUS 317L , X2CrNiMo18-15-4, 317L,UNS S31703.
1.4438 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, 1.4438 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.
