Features & Applications

The nominal deposited efficiency of CHE758 is about 110% and it is used for welding important structures fabricated 760MPa grade tensile strength low alloy steels, such as 15MnMoVN, 14MnMoNbB, WEL-TEN80 and so on. The weld metal has good performance of low temperature impact toughness and crack resistance.

Notice:

  1. The rod should be baked at 350℃ -380℃ for 1 hour before use.
  2. The surfaces to be welded must be cleaned away impurities, such as oil contamination, rust, moisture and so on.
  3. Short arc and narrow-gap welding is recommended.
