smooth surface chromium carbide overlay plate - Caster Metallugical Co.

Caster Smooth Surface Chromium Carbide Overlay plate is a bimetal plate that chromium carbide flux cored wire overlaid on the mild steel base plate using submerged arc welding process.

Based on the submerged arc welding process, We can now mass produce smooth surface chromium carbide overlay plate. (We also produce traditional CCO plate, details below the blue words)

Because we also produce the flux cored wire, so the chemical composition is flexible.

We also offer Fabrication Services like countersunk holes, stud welding, for the creation of all kinds of wear liners.

Features & Benefits：

1. Last 5 times longer than hardox 500(lab test results).
2. Considering the long lifespan and low down time, our solution is more cost efficient.
3. No weld beads.
4. Because of the smooth surface, materials will move easier, less hang up/carry back
   

Comparison with traditional CCO plates(we also produce):

Type	Surface	Weld beads	Fusion line	Cracks
Caster smooth surface chromium carbide overlay plate	Smooth, low friction. Reduced material buildup	No weld beads. So material directional flow is not required	Low dilution with a uniformed fusion line, consistent hardness and micro structure, consistent wear rates	Minimal cracks. Low residual stress between overlay and base plate. Easy for bending and fabrication
Traditional chromium carbide overlay plate	Rough, uneven, material buildup	weld beads. Directional flow over weld beads matters	High dilution and uneven fusion line. Accelerated wear rates when thickness start to reduce	Lots of cracks. High residual stress between overlay and base plate. Not easy for bending and fabrication.

Smooth Surface Wear Plate：

We produce smooth surface CCO plate for special applications. max sheet size 1.2mx3.8m, Thickness range(base plate + overlay):
6+4, 6+6, 8+4, 8+6, 8+8, 10+ 4, 10+6, 10+8, 10+10, 12+4, 12+6, 12+8, 12+12......

We are expanding our smooth surface chromium carbide overlay plate production line because of growing interests in this product.

The most distinctive feature of our smooth surface bi-metallic plate is that it has no weld beads. This feature makes the mirror-like smooth surface possible. As there are minimal cracks and residual stress between overlay and base plate, the smooth surface plate is easier for rolling and fabrication than traditional chromium carbide overlay plate.

When using traditional chromium carbide overlay plate, some material will stick to the uneven surface, causing material build-up. This problem will decrease your productivity and increase your cost. Our smooth surface overlay plate is made to solve this problem. It has the combined benefits of regular-steel's smooth surface and chromium-carbide-overlay-plate's toughness. So if you have any such requirement, please tell us.

Based on submerged welding process, The cost is higher but not prohibitive. If you are interested in our smooth surface hardfacing plates, please contact us directly.

We also produce traditional CCO plates, the following information are all for our regular CCO plates.

Cutting and Forming

caster chromium carbide plates can be easily cut to dimensions using Plasma cutting or water jet cutting. Our overlay wear plates can be rolled as per drawings, and the minimum bending radius is 20 times of the plate total thickness.
Please kindly note that hardfacing overlay plate cannot be machined or drilled by conventional methods. Both countersunk and square holes must be cut by plasma or water jet cutting.

Installation

Commonly, the welding beads shall be installed perpendicular to the materials flow direction in order to obtain maximum wear life. In our company, we offer overlay plates with two different welding bead, normal straight welding pattern and weave pattern. The weave pattern overlay plate enables it much flexible to install either perpendicular or parallel to the material flow direction, make it more wear resistant than normal pattern wear plate, which increases service time of the overlay plate.

Quality：

We have various third party certificates like BV, SGS, ISO... These credentials aside, we also promise free replacements for any quality related problems.
