There is a metallurgical bond between the wear-resistant layer of the wear-resistant steel plate alloy and the substrate. Through special equipment and automatic welding process, the high hardness self-shielding alloy welding wire is uniformly welded on the substrate. The composite layer has one to two layers or even multiple layers. During the composite process, due to the different shrinkage ratio of the alloy, uniform transverse cracks appear. It is a remarkable feature of wear-resistant steel plate.
Corten A steel chemical properties
The alloy wear-resistant layer is mainly made of chromium alloy, and other alloy components such as manganese, molybdenum, niobium, and nickel are also added. The carbides in the metallographic structure are distributed in fibrous form, and the fiber direction is perpendicular to the surface. The microhardness of carbide can reach above HV1700-2000, and the surface hardness can reach HRC58-62. Alloy carbide has strong stability at high temperatures, maintains high hardness, and also has good oxidation resistance. It can be used normally within 500°C.
Wear-resistant layer manifestations include narrow channel (2.5-3.5mm), wide channel (8-12mm), curve (S, W), etc.; mainly chromium alloys are used, and manganese, molybdenum, niobium, nickel, and boron are also added And other alloy components, the carbides in the metallographic structure are distributed in the form of fibers, and the fiber direction is perpendicular to the surface. The carbide content is 40-60%, the microhardness can reach above HV1700, and the surface hardness can reach HRC58-62.
Wear-resistant steel plates are mainly divided into three categories: general-purpose, impact-resistant and high-temperature resistant types; the total thickness of wear-resistant steel plates can reach 5.5 (2.5+3) mm as small as possible, and the thickness can reach 30 (15+15) mm; Rolling small diameter DN200 wear-resistant pipes, and can be processed into wear-resistant elbows, wear-resistant tee, wear-resistant reducer
Corten A wear-resistant steel plate application range:
Corten A wear-resistant steel plate has high wear resistance and good impact performance. It can be cut, bent, welded, etc., and can be connected to other structures by welding, plug welding, bolting, etc., and it has It is time-saving and convenient, and it is widely used in metallurgy, coal, cement, electric power, glass, mining, building materials, brick and tile industries. Compared with other materials, it has a high cost performance and has been favored by more and more industries and manufacturers.
