Abstract

The invention discloses a high-wear-resistant edge mold material and a heat treatment process thereof, and belongs to the technical field of mold materials. The high-wear-resistant edge mold materialcomprises the following components in percentage by mass: 0.45%-0.55% of C, 0.9%-1.2% of Si, 0.3%-0.6% of Mn, 4.9%-5.5% of Cr, 1.3%-1.6% of V, 1.3%-1.6% of Mo, P <= 0.03%, S<= 0.03% and the balance Feand inevitable impurities. The heat treatment process comprises the following steps: 1, pre-heat treatment: heating an edge mold material to 830-870 DEG C, keeping the temperature for 2-3 hours, andair-cooling to room temperature; 2, quenching treatment, specifically, the edge mold material treated in the step 1 is heated to 820-840 DEG C, and after heat preservation is conducted for 5-7 hours,the edge mold material is put into a quenching medium to be cooled to the room temperature; and thirdly, tempering treatment, specifically, tempering treatment is conducted on the blade mold materialtreated in the second step. By improving the components of the edge mold material and the heat treatment process, the wear resistance and comprehensive mechanical properties of the blade mold materialare greatly improved.

Description

technical field [0001] The invention belongs to the technical field of mold materials, and more specifically relates to a high wear-resistant blade mold material and its heat treatment process. Background technique [0002] Die steel is used to manufacture cold stamping dies, hot forging dies, die-casting dies and other steel types. Die steels can be roughly divided into three categories: cold-rolled die steel, hot-rolled die steel and plastic die steel, which are used for forging, stamping, cutting, die casting, etc. Due to the different uses of various molds and complex working conditions, the steel for molds should have high hardness, strength, wear resistance, sufficient toughness, and high hardenability and hardenability according to the working conditions of the molds they manufacture. Hardness and other process properties. Due to different uses and complex working conditions, the performance requirements for steel for molds are also different. [0003] H13 die stee...
