Die steel is widely used in many industries in recent years. Major enterprises will buy die steel produced by different manufacturers. What should be paid attention to when purchasing die steel? There are some relevant introductions on the jinan mold steel guide. You can learn more about it and do the relevant precautions well, so as to ensure that you can buy better die steel.

模具钢材的加工性能主要包括被切削加工性和冷热塑性变形两种，它取决于钢的化学成分、热处理后的组织和冶金生产的内部质量，近些年来，为了改善钢的可加工性，在一些钢中加入易切削元素或改变钢中的夹杂物的分布状态，从而提高模具钢材的表面质量和减少模具的磨损。

The machinability of die steel mainly includes machinability and cold hot plastic deformation. It depends on the chemical composition of steel, the microstructure after heat treatment and the internal quality of metallurgical production. In recent years, in order to improve the machinability of steel, free cutting elements are added to some steels or the distribution of inclusions in steel is changed, so as to improve the surface quality of die steel Less mold wear.

在热加工时，对一些高碳高合金的模具钢材，特别是改善碳化物的形态和分布、晶粒大小和奥氏体合金化程度十分重要，在模具的制造过程中，模具的使用寿命和制成的精度、质量、表面性能，除与模具的设计、制造精度以及机床和操作等条件外，模具钢材及热处理工艺也有密切的关系。

During hot working, it is very important to improve the morphology and distribution of carbides, grain size and austenitic alloying degree of some high carbon and high alloy die steels. In the process of die manufacturing, the service life and the accuracy, quality and surface properties of the die are related to the design, manufacturing accuracy, machine tool and operation conditions of the die, as well as the die steel and hot spot It is also closely related to technology.

据有关的统计表明，模具的早期失效因模具钢材选择不当和内部缺陷引起的约占10%左右，由热处理不当引起的约占50%左右，因此正确选择具有优良质量的模具钢材并进行正确的热处理，具有十分重要意义

According to the relevant statistics, about 10% of the early failure of the die is caused by improper selection of die steel and internal defects, and about 50% is caused by improper heat treatment. Therefore, it is of great significance to correctly select die steel with good quality and conduct proper heat treatment
