Application

Suitable for hardfacing applications requiring high wear resistance, such as roller cone bit shafts, coal augers, dredge buckets, crusher rollers, pump housings, mixer blades, etc.

Characteristics

The deposited metal contains 30-33% chromium in high-chromium cast iron surfacing electrodes. Using DC reverse polarity, the arc is relatively stable with minimal spatter and slag, and the slag is easy to remove. The surfacing layer is extremely difficult to machine even with alloy cutting tools and can only be ground.

Deposited metal chemical composition:%

The welding rod must be baked at 250±10°C for 1 hour before use.

The work piece must be preheated to above 300°C before welding to prevent cracking.
