S31703 Molybdenum austenitic stainless steel
S31703 equal material: 00Cr19Ni13Mo3, SUSS31703, X2CrNiMo18-15-4, 1.4438, 317L.
S31703 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, S31703 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.
