1.The chemical composition of the wear-resistant alloy wear-resistant layer has a carbon content of 4 ~ 5% and a chromium content of 25 ~ 30%, and the volume fraction of Cr7C3 carbide in the metallographic structure reaches more than 50%, the macro hardness is HRC56 ~ 62, and the hardness of chromium carbide is HV1400 ~ 1800. Because the carbide is vertically distributed in the wear direction, the wear resistance is more than doubled compared with the cast alloy with the same composition and hardness. The wear resistance of several typical materials is compared as follows: (1) with low carbon steel; 20 ~ 25:1 (2) and cast high chromium cast iron; 1.5 to 2.5:1
2.The substrate of the composite steel plate with good impact resistance and wear resistance is low carbon steel or low alloy. Stainless steel and other ductile materials, reflecting the advantages of bimetal, wear-resistant layer to wear the wear of the medium, the substrate bears the load of the medium, so it has good impact resistance. Can withstand impact and wear such as high drop hoppers in material handling systems.
3.The better heat-resistant alloy wear-resistant layer is recommended to be used under conditions of ≤600℃. If vanadium, molybdenum and other alloys are added to the alloy wear-resistant layer, it can withstand high temperature wear of ≤800℃. The recommended temperature is as follows: ordinary carbon steel substrate is recommended not to be higher than 380℃; Low-alloy heat-resistant steel plate (15CrMo, 12Cr1MOV, etc.) is recommended for use under conditions not higher than 540℃; Heat-resistant stainless steel substrate is recommended for use under conditions not higher than 800 ° C.
4.The alloy layer of good corrosion resistance and wear resistance composite steel plate contains a high percentage of metal chromium, so it has a certain rust and corrosion resistance. It can be used to prevent coal sticking on occasions such as dropping coal barrel and funnel.
Variety specifications Complete wear-resistant steel plate specifications, varieties, has become a commodity series. The thickness of the wear-resistant alloy layer is 3 ~ 20mm. The thickness of the composite steel plate is 6mm, and the thickness is not limited. The standard wear-resistant steel plate can be provided with 1200 or 3800×12000mm, and can also be customized according to the drawing size according to user needs. Wear-resistant steel plate is divided into ordinary type, impact resistance type and high temperature type three, 5.order high temperature wear-resistant and impact resistance composite steel plate to explain.
Wear-resistant steel can be cut, bent or crimped, welded and punched, and it can be processed into various parts that ordinary steel can be processed. The cut wear-resistant steel plate can be welded into various engineering structural parts or components.
Functions and features Weldable, good wear resistance.
