Application

Suitable for hardfacing applications requiring strong wear resistance, such as roller cone bit shafts, coal hole excavators, lifting buckets, crusher rollers, pump housings, mixer blades, etc.

Characteristics

The deposited metal contains 37-38% chromium in this high-chromium cast iron surfacing electrode. It employs DC reverse polarity, exhibiting stable arc with minimal spatter and slag. The slag is easy to remove. The surfacing layer is extremely hard to machine even with alloy cutting tools, requiring grinding instead.

Deposited metal chemical composition:%

HRC of deposited metal:HRC 60-64 Reference welding parameter: (AC、DC+)

Note

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.
