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