Abstract

The invention aims at providing high-performance heat-resistant and wear-resistant alloy. The high-performance heat-resistant and wear-resistant alloy which not only has excellent heat resistance but also has high wear resistance prolongs the service life of related parts and accordingly can reduce enterprise overhauling and maintenance costs. Moreover, the usage quantity of the expensive Ni raw material can be reduced, and the cost of the product is reduced. The high-performance heat-resistant and wear-resistant alloy consists of, in percentage by weight, 1.4-1.6% of C, 23-25% of Cr, 1-3% of Ni, 1-2% of Mo, 1.2-1.4% of Si, 0.42-0.57% of Mn, smaller than 0.04% of P, smaller than 0.04% of S and the balance of Fe.

Description

technical field [0001] The invention relates to a high-performance heat-resistant and wear-resistant alloy. Background technique [0002] There are many high-temperature impact wear conditions in industries such as thermal power generation, metallurgy, and building materials. Under these conditions, various spare parts are subjected to high-temperature oxidation and strong impact wear from solid materials. The consumption of spare parts is very serious, such as firepower The wind caps, sleeves and air pipes in fluidized bed boilers in power plants not only have to withstand high temperature oxidation at 950-1150°C, but also suffer from severe impact and wear of coal powder and ash. For this reason, domestic and foreign Many heat-resistant steels have been developed and applied, such as: heat-resistant steel represented by ZG40Cr25Ni20, ZG35Cr18Ni25Si2, ZG1Cr20Ni14Si2, ZG40Cr20Ni9Si2NRE, etc. These high-alloy steels have high oxidation resistance and good high temperature res...
