Abstract

The invention discloses a high-wear-resisting high-chromium alloy material. The high-wear-resisting high-chromium alloy material comprises the following main components in percentage by mass: 3.0%-3.3% of C, 31.0%-33.0% of Cr, 0.8%-1.0% of Mo, 0.6%-0.7% of B, 0.8%-1.0% of Cu, 0.6%-0.7% of Ni, 0.3%-0.5% of Al, 0.3%-0.4% of Ti and 0.6%-0.8% of Nb as well as the following secondary components in percentage by mass: 0.005%-0.008% of Mg, 0.01%-0.03% of Zn, less than or equal to 0.025% of S, less than or equal to 0.03% of P and the balance of Fe. According to the manner, the high-temperature resistance, corrosion resistance, wearing resistance and the like of the high-chromium alloy can be improved.

Description

technical field [0001] The invention relates to the field of metal materials, in particular to a high-wear-resistant high-chromium alloy material. Background technique [0002] Chromium is an important alloying element, has high corrosion resistance, and oxidizes slowly in air, even in red heat. Therefore, a certain amount of Cr is added to general high-temperature alloys, and the higher the Cr content, the better the high-temperature oxidation resistance and corrosion resistance of the alloy. [0003] However, the solubility of Cr in the matrix is ​​limited. When the Cr content in the alloy reaches or exceeds its saturation, complex structures will appear during use, resulting in a decrease in the mechanical properties and stability of the alloy. Therefore, the Cr content in general alloys is below 30%. The temperature resistance of this type of alloy material is not ideal enough, it cannot be used at high temperatures above 350°C, and it cannot be used in some special e...
