Abstract

The invention discloses wear-resisting steel. The wear-resisting steel comprises the following chemical components in percentage (by weight): 0.60-0.80 of C, 7.0-9.0 of Mn, 1.10-1.30 of Si, 2.40-2.80 of Cr, 0.10-0.20 of V, 0.05-0.10 of B, 0.02-0.03 of Ti, 0.02-0.05 of N, 0.6-0.8 of Ce and balance of Fe and unavoidable impurities.

Description

technical field [0001] The invention relates to the technical field of steel material processing, in particular to a wear-resistant steel. Background technique [0002] Wear is the most important way among the three damage modes (wear, corrosion, fracture) of engineering components. The loss caused by wear in the world reaches hundreds of billions of dollars every year. Therefore, it is of great importance to study wear and continuously develop wear-resistant materials with better performance. economic significance. At present, there are three types of wear-resistant materials: (1) austenitic high manganese steel, the original state is austenite, under strong external impact and high pressure stress, the transformation and strengthening of austenite to martensite occurs, and the surface layer It has high hardness, good toughness inside, excellent wear resistance and reliability. (2) Low-alloy wear-resistant steel, through reasonable chemical composition ratio and heat trea...
