如今为避免模具零件在强韧化过程中的变形或其他热处理问题，模具钢以预硬化形式供应市场已较普遍。而塑料模具钢性能要求严格，质量更高，加工精良，对热处理有利。下面我们就来看看山东塑料模具钢材料具体有什么吧。

Nowadays, in order to avoid deformation or other heat treatment problems of mold parts in the process of strengthening and toughening, it is common for mold steel to be supplied to the market in the form of pre hardening. The plastic die steel has strict performance requirements, higher quality and better processing, which is beneficial to heat treatment. Let's take a look at the specific materials of Shandong plastic mold steel.

一、易切削、抛光性好的塑料模具钢。这类钢的杂质少，组织微细均匀、无纤维方向性，制模后型腔的表面质量高。

1、 Plastic die steel with easy cutting and good polishing. This kind of steel has less impurities, fine and uniform structure, no fiber directivity, and high surface quality of the cavity after molding.

二、预硬化型塑料模具钢。该类刚应用广泛，以预硬化处理后的钢块供货，硬度达到23~48HRC，加工型腔后不再处理，无变形，可以缩短模具制造周期。代表钢号有：

2、 Pre hardened plastic die steel. This kind of steel is widely used. It is supplied with steel blocks after pre hardening treatment. The hardness reaches 23 ~ 48hrc. After processing the cavity, it is no longer processed and has no deformation, which can shorten the mold manufacturing cycle. The representative steel grades are:

三、时效硬化型塑料模具钢。这种钢一般碳含量较低，钢种加入Ni、Al、Ti、Cu、Mo等元素，模具坯料先经固溶后，在低硬度下进行加工，成形后进行时效处理，由于金属间化合物的析出，使模具硬度提高到40~50HRC，以满足使用要求。由于时效温度低，变形小而具有规律，适于制造形状复杂、精度高、超镜面以及大型塑料模具尤其是热塑性塑料制品用模具。时效硬化型塑料模具钢有马氏体时效硬化钢和析出（沉淀）硬化钢两大类。

3、 Age hardening plastic die steel. This kind of steel generally has a low carbon content. Ni, Al, Ti, Cu, Mo and other elements are added to the steel. The mold blank is processed under low hardness after solid solution, and then aged after forming. Due to the precipitation of intermetallic compounds, the hardness of the mold is increased to 40 ~ 50HRC to meet the use requirements. Due to low aging temperature, small deformation and regularity, it is suitable for manufacturing complex shapes, high precision, super mirror surfaces and large plastic molds, especially molds for thermoplastic products. Age hardening plastic die steels include martensitic age hardening steels and precipitation hardening steels.

四、整体淬硬型塑料模具钢。国外一般都是借用高耐磨性冷作模具钢和热作模具钢。如美国的A2（Cr5Mo1V）、D3（Cr12）、D2（Cr12Mo1V）等冷作模具钢和H13（4Cr5MoSiV1）等热作模具钢。

4、 Integrally hardened plastic die steel. Cold working die steel and hot working die steel with high wear resistance are generally used abroad. Such as A2 (Cr5Mo1V), D3 (Cr12), D2 (cr12mo1v) and other cold work die steels in the United States and H13 (4Cr5MoSiV1) and other hot work die steels.

五、耐腐蚀塑料模具钢。有些塑料制品如聚氯乙烯、氟塑料、阻燃塑料等，在加工过程中对模具具有腐蚀作用，因此一般采用马氏体不锈钢和沉淀硬化型不锈钢。

5、 Corrosion resistant plastic die steel. Some plastic products, such as PVC, fluoroplastics, flame-retardant plastics, etc., have corrosive effects on the mold during processing, so martensitic stainless steel and precipitation hardening stainless steel are generally used.

当塑料制品的产量不大、要求不高时，可以在模具表面采取镀铬保护措施，但大多数情况需采用耐腐蚀钢制造模具。

When the output of plastic products is not large and the requirements are not high, chromium plating protection measures can be taken on the mold surface, but in most cases, corrosion-resistant steel should be used to make the mold.

六、无磁塑料模具钢。为了适应磁性塑料制品的生产，国外发展了一些无磁塑料模具钢，将模具钢通过时效硬化处理得到符合要求的硬度、强度和低导磁率。

6、 Non magnetic plastic die steel. In order to adapt to the production of magnetic plastic products, some non-magnetic plastic die steels have been developed abroad. The die steels are age hardened to obtain the required hardness, strength and low permeability.
