wear resistance of nm400 structural steel prices in July 2021
Machining of wear resistance of NM400, wear resistant steel plate: wear resistant steel plate has good cutting and shearing properties. During machining, the cutting tools and feeding speed should be used reasonably according to the hardness of steel plate. Common tools are made of high speed steel or cemented carbide steel, and carbide surface tools are required for grinding. Wear resistant steel plate can be welded to structural steel by arc welding.
Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the wear resistance of NM400 quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After wear resistance of NM400 quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
ArcelorMittal USA said wear resistance of NM400 it was planning to work with the United Steelworkers union "to minimize the impact on its employees. The company will continue to communicate with its customers to understand the market impact of the outbreak of covid-19, which may require additional capacity optimization to maintain a balance between supply and demand.
The advantages of wear resistance of NM400, steel plate produced from coil: price is cheap and length can be freely determined; transportation is convenient, no need to consider according to the size of steel plate; cutting is convenient, according to the actual needs of steel plate size cutting, and finally can effectively save materials. The disadvantage of steel plate produced from coil: there will be great welding deformation during welding, which is difficult to adjust. Therefore, the steel plate produced from coil can not be used for parts with high requirements on appearance quality.
