加工模具时用的，由于模具的用途很广，各种模具的工作条件差别很大，模具的工作条件不同，对其材料的性能要求也不同。下面来讲讲济南模具钢的基本性能及选用标准内容吧。

The working conditions of all kinds of molds are very different, and the working conditions of the molds are different, and the performance requirements of the materials are also different. Let's talk about the basic properties and selection standards of Jinan die steel.

冷冲压模具要求其材料具有高的强度，良好的塑性和韧性，高的硬度和耐磨性;

Cold stamping die requires its material to have high strength, good plasticity and toughness, high hardness and wear resistance;

冷挤压模具要求其材料具有高强度、高韧性、高淬透性以及良好的耐磨性、热稳定性和切削加工性;

The cold extrusion die requires its material to have high strength, high toughness, high hardenability, good wear resistance, thermal stability and machinability;

热作模具用钢要求在工作温度下保持高的强度和韧性、良好的抗蚀性、热稳定性和优良的热疲劳抗力。

The steel for hot work die is required to maintain high strength and toughness, good corrosion resistance, thermal stability and excellent thermal fatigue resistance at working temperature.

模具的各项性能要求有时是相互矛盾的。一般硬度越高，耐磨性就越高。在同样的硬度下，钢材碳含量越高，耐磨性也就越高。热稳定性与加入元素的种类及数量有关，只有在高合金含量的情况下，才能达到所要求的抗软化能力。

The performance requirements of the mold are sometimes contradictory. Generally, the higher the hardness, the higher the wear resistance. Under the same hardness, the higher the carbon content of the steel, the higher the wear resistance. The thermal stability is related to the type and quantity of the added elements. Only in the case of high alloy content can the required softening resistance be achieved.

韧性则与前二者相反.碳化物中合分元素增加，钢材变脆，这样就形成耐磨性和韧性之间以及稳定性和韧性之间的两对矛盾。

Toughness is opposite to the former two With the increase of alloying and separating elements in carbides, the steel becomes brittle, thus forming two pairs of contradictions between wear resistance and toughness and between stability and toughness.

在选择模具材料时，应先考虑模具的某些基本性能须能适应所制造模具的需要。在一般情况下，主要是钢的耐磨性、韧性、硬度和热硬性以及热疲劳抗力，这四种性能可以比较多方面地反映模具材料的综合性能，可以在一定程度上决定其应用范围。

When selecting the mold material, some basic properties of the mold should be considered first to meet the needs of the manufactured mold. In general, it is mainly the wear resistance, toughness, hardness, thermal hardness and thermal fatigue resistance of steel. These four properties can reflect the comprehensive properties of mold materials in many aspects and determine their application range to a certain extent.

当然对于一种模具的要求来说.可能其中的一种或两种性能是主要的，而另外的一种改两种是次要的。更多相关内容就来我们网站https://www.jnqhmj.com咨询了解吧。
