Problems solved by technology

[0002] With the development of science and technology, the scope of mold application is becoming more and more extensive. For the manufacture of product molds with multiple varieties, small batches or frequent updates and modifications, such as injection molds, blow molds, and compression molds, it is required to have manufacturing It has the characteristics of short cycle, low production difficulty and low cost, while the mold manufacturing cost usually used in the prior art is high and the cycle is long
Pure metallic iron cannot meet the requirements such as plasticity, hardness, strength, etc., so alloying elements are usually added to improve its physical and mechanical properties

Abstract

The invention relates to a high temperature resistant die steel. The die steel comprises, by weight, 1-3.5 parts of C, 0.05-0.08 parts of Zn, 0.013-0.025 parts of Mg, 0.057-0.086 parts of lime powder, 0.036-0.05 parts of Sn, 0.03-0.065 parts of Sb, 0.15-0.25 parts of Pb, 0.05-0.063 parts of Y and 80-95 parts of Fe. The die steel has the advantages of scientific and reasonable component proportions, strong high temperature resistance, stable performances, great prolongation of the service life, and realization of unlikely deformation, high tensile strength and high molding precision in use.

Description

technical field [0001] The invention relates to a high temperature resistant die steel. Background technique [0002] With the development of science and technology, the scope of mold application is becoming more and more extensive. For the manufacture of product molds with multiple varieties, small batches or frequent updates and modifications, such as injection molds, blow molds, and compression molds, it is required to have manufacturing It has the characteristics of short cycle time, low production difficulty and low cost, while the mold manufacturing cost usually used in the prior art is high and the cycle time is long. Pure metallic iron cannot meet the requirements such as plasticity, hardness, strength, etc., so alloying elements are usually added to improve its physical and mechanical properties. [0003] Therefore, in order to solve the above problems, a new technical solution is provided. Contents of the invention [0004] The invention provides a high tempera...
