Chromium Carbide Hardfacing Welding Overlay Wear Liner
Overview:
Chromium Carbide Hardfacing Welding Overlay Wear Liner the chemical composition of the high wear resistance alloy layer contains 4 to 5% carbon and 25 to 30% chromium.
The volume fraction of Cr7C3 carbide in the metallographic structure reaches more than 50%, and the macro hardness is HRC58 to 63.
The hardness of chromium carbide is HV1400 ~ 1800, which is higher than the hardness of quartz in sandstone HV800 ~ 1200.
Since carbides are distributed vertically in the direction of wear, even when compared with casting alloys of the same composition and hardness, the wear resistance is more than doubled.

Q:. What is the recommended welding process for this plate?
FAQ
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.
