热作模具钢在工作中既受力的作用，又受温度的作用，从而使模具的工作条件复杂化，对模具材料的要求也较高。下面来讲讲山东热作模具钢的工作条件及其性能分类。

The hot work die steel is subject to both force and temperature, which complicates the working conditions of the die and requires high die materials. Now let's talk about the working conditions and property classification of Shandong hot work die steel.

热作模具钢的工作条件

Working conditions of hot work die steel

（1）在室温及工作温度下具有能满足服役条件的力学性能，如较高的高温强度和硬度、良好的韧性和耐磨性等。

(1) At room temperature and working temperature, it has mechanical properties that can meet the service conditions, such as high temperature strength and hardness, good toughness and wear resistance.

（2）在工作时应具有良好导热性、优良的耐热疲劳性、高的热稳定性，以及较好的抗氧化性能。

(2) It shall have good thermal conductivity, excellent thermal fatigue resistance, high thermal stability and good oxidation resistance when working.

（3）模具材料应具有较好的热磨损性和热熔损性。

(3) The die material shall have good thermal wear resistance and thermal melting resistance.

（4）具有良好的加工工艺性能（包括可加工性、热处理、工艺性、锻造性等）。

(4) It has good processing performance (including machinability, heat treatment, processability, forgeability, etc.).

总之，热作模具钢的选择应根据模具的生产条件和工作条件的需要，结合模具的基本性能和相关因素综合考虑。

In a word, the selection of hot work die steel should be based on the needs of die production conditions and working conditions, combined with the basic performance of the die and related factors.
