JIS SM490YB plates chemical composition

JIS SM490YB plates, Wear resistant steel plate has been used in many fields, and its roughness requirements are different for different applications. In the process of production, the roughness of production equipment such as the work roll of leveller will be shown on the surface. It has been proved that both the roughness of work roll surface and the rolling force have influence on the roughness value of tube surface, and there is a nonlinear positive correlation.

NM400 wear resistant steel plate has a very high mechanical strength; its mechanical properties are 3 to 5 times that of ordinary low alloy steel plates; it can improve the wear resistance of mechanical related parts; therefore improve the service life of machinery; reduce production costs. The surface hardness of the product JIS SM490YB plates is usually Reached 360 - 450HB. NM400 wear resistant steel plate is used for processing and manufacturing of wear-resistant and wearing parts for mining and various construction machinery.

The location weld of JIS SM490YB plates, wear-resistant steel plate is only allowed to be welded on the base metal surface with the electric welding rod for welding the base metal; in the welding of the base course, the base weld shall be strictly prevented from melting to the transition layer or even the multiple layer weld of stainless steel, so as to prevent a small amount of high chromium and high nickel surfacing wear-resistant steel plate components diluted into the carbon steel weld to form martensite structure and harden.
