Abstract

The invention discloses ultra-wear-resistant H13 mold steel, and belongs to the field of mold steel. The ultra-wear-resistant H13 mold steel comprises the following chemical element ingredients in parts by weight: 0.46 to 0.49 part of C, 0.81 to 0.92 part of Si, 0.32 to 0.46 part of Mn, 0.008 to 0.011 part of P, 0.001 to 0.003 part of S, 4.36 to 6.25 parts of Cr, 0.04 to 0.23 part of Ni, 0.01 to 0.1 part of Cu, 1.01 to 1.36 parts of Mo, 0.08 to 1.27 parts of V and the balance of Fe. By aiming at the problem of poor wear resistance of the H13 mold steel in the prior art, the ultra-wear-resistant H13 mold steel has the advantages that the wear-resistant performance of the H13 mold can be improved.

Description

technical field [0001] The invention relates to the field of die steel, in particular to a super wear-resistant H13 die steel. Background technique [0002] Processing molded parts with molds has a series of advantages such as high production efficiency, good quality, material saving and low cost, and has a wide range of applications. Hot work die steel is an important type of die material. Since hot work dies work at high temperatures for a long time, their structure will change as the service time prolongs, and their performance will change accordingly. Therefore, this requires Hot work die steel has good strength and toughness, cold and heat fatigue performance and high temperature thermal stability. [0003] H13 steel is C-Cr-Mo-Si-V steel, which is widely used in the world. The post-forging heat treatment process of H13 series steel generally adopts the following process: the forging material is slowly cooled after heat preservation at 830-880 ° C or isothermal sphero...
