Overlay Wear Plates – OVERLAY-PLATE is welded by Chromium carbide overlay on a mild steel backing plate. Manufactured by our own design’s welding machine with exclusive technique.

OVERLAY-PLATE has excellent performance in abrasion and impact.
1) Chemical composition: C 4.0~5.5% Cr 21%~27%
2) Hardness: 58-62HRC
3) Standard sheet size we can produce is 1500x3000mm.We can also cut into your requried sizes.
4) Thickness we can produce 4+4, 6+4, 6+6, 8+5, 8+6, 10+5, 10+9, 10+10, 12+12, 12+17, 10+20.
Typical applications: Concrete mixer, Hopper/Chute, fan industry,coal industry, mining machinery(Buckets), construction machinery(truck bed).
Holes, studs can be added or machined.
We could bend or formed the wear plates to required shapes.

The bimetallic (meaning two types of metals)product starts with standard steel base plate that is then fused or overlaid with chromium carbide. Chromium carbide metallurgically bonds to the steel’s surface to form a protective and durable surface that will not separate from the base metal. Chromium carbide overlay steel plate is extremely hard, resistant to both wear and impact, and with stands high temperatures.

>> Standard plate size is 1475*3050mm, other sizes on request
>> Standard thickness ranges from 4 on 6 to 12 on 12
>>The weld material is with following chemistry: Carbon 4.2~5.45% , Cr 25.3~30%, Si 0.7~1.5%, Mn 0.2~1%, Ni 0.1~0.4%, B 1~1.5%, Fe-balance
