Audited Supplier Chrome Carbide Overlay Wear Plate are manufactured by welding one or multiple wear resistant layers on a medium or low carbon steel base plate.
The overlay alloy has a high amount of chromium carbide hard particles which makes the plate have good wear and impact resistance.
Overlay thickness range: 3-25mm
Wear plate size: 1500*3000, 1400*3000,1400*3400, 1400*3500, 2100*3500, customized.
Chrome Carbide Overlay Wear Plate are used to make many complex wear parts to be positioned in high wear places.
We have several equipment to transform our plates: Eight sets of plasma cutting machine , 6 bending machines and pressing machines,
with high processing capacity operated by engineers and technical experts, we can provide wear plate cutting, bending, bolting, punching and welding according to customer's drawings.
1.Drilling Holes
Straight holes and Countersunk holes.
2.Bolt embedded welding in the back
Embedding the Pre-processed bolt in the back of wear plate.
3.Bending
Wear plate can be cold formed and made into curve or cone.
4.Welding
Wear plate can be welded and assembled into kinds of wear parts.
Wear pipe, Elbow, Square to round transition
We also introduced in our factory automatic welding equipment for pipes (internal and external) meeting the increasing demand for small diameter wear pipes.
Wear pipes
1. Steel pipe with regular base material + overlay, pipes are welded with our automatic welding machine resulting in good shaped and flat surface pipes.
2. Bending the wear plate into round pipes
3. Assembling the wear plate into square pipes
Automatic welding, metallurgical bonding, available to weld the maximum pipe diameter of 80mm and maximum pipe length of 3000mm.
Wear elbow
Weld directly on the elbow wall
using wear plate to make lobster back bend
wear plate used to make tube with round top and square bottom
Characteristics
Q235/Q345 base hardfaced high wear resisting clad plate
1, high wear resistance
Carbon content in the chemical composition of the alloy layer of 4 ~ 6%, the chromium content up to 25 ~ 30%, the microstructure of Cr7C3 carbide volume fraction of 45% or more, the macro hardness HRC56-62, the hardness of chromium carbide is HV1400 ~ 1800, higher than the hardness of sand quartz in HV800 ~ 1200.Because the carbide into vertical distribution in the direction of wear, even compared with the same composition and hardness of casting alloy, wear-resisting performance is more than double.
2, good resistance to impact
The ground floor of the wear-resistant composite plate is low carbon steel or low alloy.Ductile material such as stainless steel, and demonstrate the superiority of bimetal, wear-resisting layer of abrasion resistance of medium wear and substrate under medium load, thus has a good resistance to impact.Can withstand conveying system under high head hopper and other impact and abrasion.
3, good heat resistance
Wear-resisting layer is recommended to use under the working condition of 600 ºC or less use, if adding vanadium alloy layer, such as molybdenum alloy, can withstand the high temperature of 800 ºC or less wear and tear.Recommended temperature is as follows: ordinary carbon steel substrate recommended is not higher than 380 ºC condition of use;Low alloy heat-resistant steel plate (15 crmo, 12 cr1mov, etc.) recommended base plate is not higher than 540 ºC condition of use;Heat resistant stainless steel substrates recommend used at not higher than 800 ºC condition.
4, good corrosion resistance, wear resistance of composite steel plate containing high percentage of chromium metal alloy layer, so have ability to rust and corrosion.Used for coal cylinder and hopper, etc can be done to prevent caking coal.
