Comparison of wear resistance with several typical materials

(1) And low-carbon steel; 20-25:1 (2) and as cast high chromium cast iron; 1.5-2.5:1
The substrate of the wear-resistant composite steel plate with good impact resistance is low-carbon steel or low alloy. Stainless steel and other ductile materials reflect the superiority of bimetallic materials. The wear-resistant layer resists the wear of the wear medium, and the substrate bears the load of the medium, thus having good impact resistance. It can withstand the impact and wear of high drop hoppers in the material conveying system.
A better heat-resistant alloy wear-resistant layer is recommended to be used under working conditions ≤ 600 ℃. If vanadium, molybdenum and other alloys are added to the alloy wear-resistant layer, it can withstand high-temperature wear at ≤ 800 ℃. The recommended temperature for use is as follows: ordinary carbon steel substrates are recommended for use under operating conditions not exceeding 380 ℃; Low alloy heat-resistant steel plates (15CrMo, 12Cr1MOV, etc.) are recommended for use under operating conditions not exceeding 540 ℃; It is recommended to use heat-resistant stainless steel substrates under operating conditions not exceeding 800 ℃.
The alloy layer of a good corrosion-resistant and wear-resistant composite steel plate contains a high percentage of metallic chromium, so it has a certain degree of rust prevention and corrosion resistance. Used in situations such as coal chute and funnel to prevent coal sticking.
The variety and specifications of wear-resistant steel plates are complete, and there are many varieties, which have become a series of products. The thickness of the wear-resistant alloy layer is 3-20mm. The minimum thickness of composite steel plate is 6mm, with unlimited thickness. Standard wear-resistant steel plates available in 1200 or 3800 × 12000mm, can also be customized and processed according to the drawing size according to user needs. Wear resistant steel plates are now divided into three types: ordinary type, impact resistant type, and high-temperature type. When ordering high-temperature wear resistant and impact resistant composite steel plates, it is necessary to specify.
Convenient processing performance wear-resistant steel plates can be cut, bent or curled, welded, and punched, and can be processed into various components that can be processed by ordinary steel plates. The cut wear-resistant steel plate can be welded together into various engineering structural components or components.
Capable of welding and good wear resistance.
