Features of bimetal wear-resistant composite steel plate
The bimetal wear-resistant composite steel plate adopts the open arc self-protection fully automatic surfacing process. A layer of high-alloy wear-resistant layer with high hardness and high wear resistance is surfacing on the surface of ordinary steel plate or stainless steel. The wear-resistant steel plate It has bimetallic properties, that is, high wear resistance of the working layer and high plastic toughness of the base layer, and can realize reeling, welding, plasma cutting, mechanical connection processing, etc.
The thickness of the wear-resistant layer is uniform and the surface is smooth. The flatness of the entire steel plate is equivalent to that of ordinary carbon steel plates. There are stress release cracks on the surface of the wear-resistant layer. The cracks only exist in the wear-resistant layer of the surfacing and do not extend to the base layer. The stress The released cracks can greatly reduce the residual stress and deformation of the matrix caused by the surfacing process, thereby avoiding a reduction in the strength of the matrix and not affecting the performance of the wear-resistant plate.
The main component of the wear-resistant layer is high-carbon and high-chromium alloy. According to different requirements and usage conditions, high-temperature resistant wear-resistant plates also contain alloy elements such as MO, W, V, B, Nb, Ti, etc. The metallographic structure of the wear-resistant layer The structure is provided as eutectic + M7C3 primary carbide or complex carbide, which can achieve high wear resistance at normal temperature, high temperature, strong impact, medium impact, and low stress impact.
