• Applications
  • Welding of extra-low carbon 18%Cr-8%Ni stainless steel such as AISI 304L.
  • Characteristics
    • - W 308L has extra-low carbon austenitic structure which contains suitable ferrite.
    • - Crack resistibility is good and intergranular corrosion resistibility is superior to that of W 308.
    • - It is quite efficient because its burn-off rate and deposition rate are high because comparatively high amperage can be used.
  • 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.
    • - Remove dirts such as oil and dust from the groove.
