China Surfacing Welding D802 Cobalt-Based Electrode Best Price

Product Name: D802 cobalt-based welding rod
Model: EDCoCr-A-03
Description:
The cobalt-based surfacing electrode of the cobalt-chromium-tungsten alloy core
adopts DC reverse connection, and the surfacing metal can maintain good wear
resistance and corrosion resistance when working at 650ºC.
Uses: Used in occasions where good wear resistance and corrosion resistance
can be maintained when working at around 650°C, or in places subject to impact
and interlocking heat and cold, such as surfacing high temperature and high pressure
valves and hot scissors blades.
