Molybdenum austenitic stainless steel SUS317L

SUS317L equal material: 00Cr19Ni13Mo3, 317L, X2CrNiMo18-15-4, 1.4438, UNS S31703.

SUS317L 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, SUS317L 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.
