• Applications
  • Welding of 18%Cr-8%Ni steel.
  • Characteristics on Usage
    • - W 308 is a lime-titania type electrode for 18%Cr-8%Ni steel with good usability.
    • - Its weld metal has austenitic structure, crack resistibility is good.
    • - Furthermore, its heat and corrosion resistibility are also good.
  • Notes on Usage
    • - Keep the arc as short as possible and use currents as low as possible.
    • - Dry the electrodes at 250~300℃(482~572℉) for 60~90 minutes before use.
