模具钢很多时候的工作会承受着很大的冲击力，模腔和高温金属接触，反复地加热和冷却，其使用条件不算好，但其本身的性能好，所以一般不会出什么问题，下面来讲解一番模具钢性能及抗失效评价要求内容吧。

Mold steel often works under great impact. The mold cavity contacts high-temperature metal and is heated and cooled repeatedly. Its service conditions are not good, but its own performance is good, so generally there will be no problems. Let's explain the requirements of mold steel performance and anti failure evaluation.

山东模具钢厂家认为热作模种类繁多，工作条件差别很大，对材料的性能及其相互配合的要求也不同。此外，不考虑机械零件或模具部件薄弱环节的实际有效性能，即抵抗失效的能力，由于材料内部因素和使用条件外部因素的影响，往往与特定条件下标准样品测得的数据不一致。

Shandong die steel manufacturers believe that there are many kinds of hot working dies, the working conditions are very different, and the requirements for the properties of materials and their mutual cooperation are also different. In addition, the actual effective performance of weak links of mechanical parts or mold components, that is, the ability to resist failure, is often inconsistent with the data measured by standard samples under specific conditions due to the influence of internal factors of materials and external factors of service conditions.

因此，除了测量材料的常规性能外，还需要根据和模拟实际模具工作条件进行使用特性的研究。如果离开模具的使用条件和材料的性能要求，就没有明确的针对性。

Therefore, in addition to measuring the conventional properties of materials, it is also necessary to study the service characteristics according to and simulate the actual working conditions of molds. If you leave the use conditions of the mold and the performance requirements of the material, there is no clear pertinence.

因此，如何根据模具的不同工况、材料特性和失效模式，建立并正确使用模具性能的评价体系，找出材料内因与模具使用寿命之间的变化规律，仍然是当前模具行业发展中迫切需要的具有普遍指导意义的基础性工作。更多相关内容您可以来网站https://www.jnqhmj.com咨询我们。

Therefore, how to establish and correctly use the mold performance evaluation system according to the different working conditions, material characteristics and failure modes of the mold, and find out the change law between the internal causes of materials and the service life of the mold is still the basic work with universal guiding significance that needs to be solved urgently in the development of the mold industry at present.
