▎Applications and Features

  • KTS-347Si welding wire is an austenitic stainless steel containing 20% Cr, 10% Ni, Nb, and Si.
  • The addition of niobium enhances resistance to intergranular corrosion and improves high-temperature strength.
  • With higher silicon content, it offers excellent weld pool fluidity, making it suitable for welding thin plates and tubing.
  • KTS-347Si is recommended for welding applications in food processing machinery, medical equipment, pressure vessels, and petrochemical facilities.
