钢材在建筑行业中不可或缺，而且随着建筑行业的增多，钢材的需求量也在日益递增，同时，模具钢的应用非常广泛，我们今天要说的就是常见的几种耐热性的模具钢，热作模具钢的性能特点，包括有低耐热高韧性模具钢、中耐热韧性钢、高耐热热作模具钢、特殊用途热作模具钢。接下来天成模具钢给大家分享一下我们常见的几种热作模具钢。
Steel is indispensable in the construction industry, and with the increase of the construction industry, the demand for steel is also increasing day by day. At the same time, die steel is widely used. What we want to say today is the performance characteristics of several common heat-resistant die steels, hot work die steels, including low heat-resistant and high toughness die steels, medium heat-resistant and high heat-resistant hot work die steels Special purpose hot working die steel. Next, Tiancheng die steel will share with you several common hot work die steels.
一、低耐热高韧性模具钢：主要是用来加工承受大冲击载荷的热锻模，因为这类模具要求钢的冲击韧性好、淬透性高、导热性能好，并且有较高的热疲劳抗力，能够在400℃的高温工作环境下承受急冷急热的工作条件。
1、 Low heat resistance and high toughness die steel: it is mainly used to process hot forging dies bearing large impact load, because this kind of die requires good impact toughness, high hardenability, good thermal conductivity, high thermal fatigue resistance, and can withstand the working conditions of rapid cooling and rapid heating under the high-temperature working environment of 400 ℃.
二、中耐热韧性钢：该类钢淬透性很好，100mm直径的工件空冷即能淬透，这类模具钢材综合性能好，在淬火、回火热处理工艺条件下，具有高硬度、高强度以及良好的韧性、塑性配合。中耐热韧性钢广泛应用于加工热变形用模具（如机锻模、高速锤锻模）和压铸模。
2、 Medium heat-resistant and ductile steel: this kind of steel has good hardenability, and the workpiece with diameter of 100mm can be quenched through air cooling. This kind of die steel has good comprehensive performance. Under the conditions of quenching and tempering heat treatment, it has high hardness, high strength, good toughness and plastic matching. Medium heat-resistant and ductile steel is widely used in processing dies for thermal deformation (such as machine forging die, high-speed hammer forging die) and die-casting die.
三、高耐热热作模具钢：这类钢是有较高耐热性，在高温下仍能保持一定的高温硬度和高温强度，同时具有较高的淬透性和耐磨性，可以在600—700℃的高温下工作，有强烈的二次硬化效果，回火抗力好，断裂韧度均较高。
3、 High heat-resistant hot working die steel: this kind of steel has high heat resistance, can still maintain a certain high-temperature hardness and high-temperature strength at high temperature, and has high hardenability and wear resistance. It can work at high temperature of 600-700 ℃, has strong secondary hardening effect, good tempering resistance and high fracture toughness.
