Abstract

The invention discloses a high-strength impact-resistant wear-resistant material. The high-strength impact-resistant wear-resistant material is prepared from the following components: greater than 0.64 mass percent and less than 0.71 mass percent of C, greater than 0.20 mass percent and less than 0.40 mass percent of Si, greater than 1.90 mass percent and less than 2.05 mass percent of Mn, greater than 0.90 mass percent and less than 1.05 mass percent of Cr, greater than 0.02 mass percent and less than 0.05 mass percent of Al, greater than 0.01 mass percent and less than 0.02 mass percent of P, greater than 0.001 mass percent and less than 0.015 mass percent of S, and the balance of Fe and unavoidable impurities. The wear-resistant material disclosed by the invention is high in strength, and good in impact resistance and wear resistance.

Description

technical field [0001] The invention relates to the field of wear-resistant materials, in particular to a high-strength impact-resistant and wear-resistant material. Background technique [0002] At present, the most widely used wear-resistant materials in mining, cement, power system and other industries are mainly divided into two types, one is wear-resistant materials using chromium alloys, and the other is wear-resistant materials using martensite and bainite matrix. Wear-resistant materials, such as low-chromium cast iron wear-resistant materials, high-chromium cast iron wear-resistant materials, etc. Most of the cast iron processes used are still manual molding, green sand casting, and a few manufacturers use metal mold casting. Low-chromium cast iron and high-chromium cast iron wear-resistant materials generally have disadvantages such as high cost; wear-resistant materials with martensite and bainite matrix have disadvantages such as low service life and poor wear r...
