overlay wear plate

Chromium carbide wear plates

  • Chromium carbide wear plates or steel liners are used in many applications where friction between two parts or materials creates degradation. Wear plate steel plate may bolt onto a machine that slides in and out or up and down in a manufacturing process, while they can also be found where manufactured parts or minerals are regularly rubbing or abrasively contacting the machined plate.

Overlay welding machine – The Ultimate FAQ Guide
