The high chromium surfacing bimetal wear plate is a Cr7C3 carbide with a chromium content of up to 28% and a volume fraction of more than 50% as the main wear-resistant layer on an ordinary steel plate (Q235 (A3)).
It has deformable and weldable performance, impact resistance, wear resistance and other performance characteristics, and can be directly cut, punched, rolled, deformed，so as to be processed into wear-resistant parts.
Compared with many wear-resistant materials, Qi Shuai high chromium surfacing bimetal wear plate has its irreplaceable significant features:
1.High abrasion resistance
The chemical composition of the alloy layer has a carbon content of 4-5% and a chromium content of 15-30%. The volume fraction of Cr7C3 carbides in the metallurgical structure reaches more than 50%.
Compared with several typical materials, the wear resistance is as follows:
(1) Hardness is low carbon steel; 20 times (2) Hardness is high manganese steel; 5 to 10 times
2.Good impact resistance
The bottom layer of Qi Qishuai high chromium surfacing bimetal wear plate is a low-carbon steel plate, which can reflect the superiority of bimetal.
It can withstand the impact and wear caused by high drop in the material conveying system.
3.Good heat resistance
Usually this wear plate can be used under ≤600 ℃
If vanadium, molybdenum and other alloys are added in the process of surfacing welding, it can withstand high temperature wear of 800-1000 ° C.
4.Good corrosion resistance
5. Strong applicability
The thickness of the wear-resistant alloy layer is 3 to 20 mm.
At present, standard wear-resistant composite steel plates are available in 1400, 1500, 2100 × 2900, 3000, and 3500mm.
The high chromium surfacing bimetal wear plate exported to Pakistan, Russia, Mongolia, Indonesia, India, Kazakhstan and many other countries all over the world.
