Product Description
The surface alloy layer of this product has high hardness and excellent wear-resistant performance.The base metal is a common rolled plate with good toughness and plasticity.The wear-resistant alloy layer and the base metal are metallurgy combined and firmly combined in service,wear is resisted by the high hardness of the surface allov aver. And the impact of external force is resisted by the strength and toughness of the matrix.

Q1: Why are there so many cracks?
A1. Due to the cooling rates of dissimilar metals. Our hard facing plate for coal chute liner is manufactured by welding which results in high temperatures. During the cooling, the plate goes through a stress relieving which is a natural process and does not effect the performance of the plate. The stress relief cracks should be between 3/4" - 2" apart. The cracks can be touched up by our chrome carbide welding rod.Q2: What is the best method of attachment?
A2. hard facing plate for coal chute liner is usually attached by countersunk bolts, welding studs, perimeter welding, or plug welding. Some methods are better suited than others depending on the specific application. For more detail on each method see the installation section.
Q3: Can hard facing plate for coal chute liner be drilled or machined?
A3. hard facing plate for coal chute liner cannot be machined or drilled. It can however be ground. Mild steel inserts are used to create countersunk or counter bored holes. hard facing plate for coal chute liner can be cut using plasma, Grinding wheel saw, or air-arc gouging.
Q4:MOQ?
A4.Our product has no limit to quantity, it can be ordered according to customer requirement.
