Super-toughness wear-resistant alloy material and preparation method thereof

Abstract

The invention provides a super-toughness wear-resistant alloy material. The super-toughness wear-resistant alloy material is prepared from the following alloy raw materials in percentages by mass: 2.0-2.1% of C, 0-0.03% of P, 0-0.02% of S, 0.01-0.4% of B, 0.002-0.03% of Ti, 0.001-0.003% of Zr, 0.2-0.5% of Mn, 1.8-1.9% of Cr, 0.26-0.28% of Mo, 0.85-0.9% of Si, 0.006-0.007% of Al, 0.03-0.06% of Cu,0.2-0.4% of Ni, 0.02-0.04% of Co and the balance Fe and inevitable impurity elements. The invention aims to provide the super-toughness wear-resistant alloy material and a preparation method thereof.The alloy material prepared by the process is relatively great in toughness, relatively long in service life and relatively good in wear-resisting property.

As an important support to promote the development of high-tech fields, wear-resistant materials are one of the high-tech materials that countries in the world are eager to develop. Wear-resistant materials are widely used as a special material for some harsh working environments. Abrasive materials are often used in environments with a lot of dust, high corrosiveness, heavy load, and strong impact. These harsh environments will cause serious wear and tear to wear-resistant materials, greatly reducing the service life of materials. At present, the proportion of steel-based wear-resistant materials in all wear-resistant materials used is relatively large, but there are many problems in the use of steel-based wear-resistant materials. For example, the hardness of steel-based wear-resistant materials is often relatively large, but it has a large The brittleness and lack of toughness often cause various quality problems in the work, which affects the normal operation of the work.
