熱作模具鋼在工作中既受力的作用，又受溫度的作用，從而使模具的工作條件復雜化，對模具材料的要求也較高。下面來講講山東熱作模具鋼的工作條件及其性能分類。

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.

熱作模具鋼的工作條件

Working conditions of hot work die steel

（1）在室溫及工作溫度下具有能滿足服役條件的力學性能，如較高的高溫強度和硬度、良好的韌性和耐磨性等。

(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）在工作時應具有良好導熱性、優良的耐熱疲勞性、高的熱穩定性，以及較好的抗氧化性能。

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

（3）模具材料應具有較好的熱磨損性和熱熔損性。

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

（4）具有良好的加工工藝性能（包括可加工性、熱處理、工藝性、鍛造性等）。

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

總之，熱作模具鋼的選擇應根據模具的生產條件和工作條件的需要，結合模具的基本性能和相關因素綜合考慮。

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.
