▎Applications and Features

  • KTS-309LMo is a low-carbon austenitic stainless steel containing 23% Cr, 13% Ni, and 2.5% Mo.
  • The addition of molybdenum enhances resistance to intergranular corrosion and improves high-temperature strength.
  • Its low carbon content further increases resistance to sensitization.
  • KTS-309LMo is particularly suitable for dissimilar welding between 316L or duplex stainless steels and carbon steels.
