When processing molds, it is necessary, because the application fields of molds are very wide, and the operation preconditions of various molds are very different. Therefore, the standards of raw materials for manufacturing molds are very wide, and the most widely used raw materials in molds are mold steel. From high-speed steel, alloy steel, powder steel, stainless steel, die steel and its unique wear resistance. According to the main purpose, die steel can be generally divided into three categories: cold work die steel, hot work die steel and plastic die steel.

一、冷作模具钢

1、 Cold working die steel

冷作模具钢主要用于制造对冷状态下的工件进行压制成型的模具。如：冷冲裁模具、冷冲压模具、冷拉深模具、压印模具、冷挤压模具、螺纹压制模具和粉末压制模具等。冷作模具钢的范围很广，从各种碳素工具钢、合金工具钢、高速工具钢到粉末高速工具钢和粉末高合金模具钢。

Cold working die steel is mainly used to manufacture dies for pressing and forming workpieces in cold state. Such as: cold blanking die, cold stamping die, cold drawing die, embossing die, cold extrusion die, thread pressing die and powder pressing die. The range of cold working die steel is very wide, from all kinds of carbon tool steel, alloy tool steel, high-speed tool steel to powder high-speed tool steel and powder high-alloy die steel.

二、热作模具钢

2、 Hot work die steel

热作模具钢主要用于制造对高温状态下的工件进行压力加工的模具。如：热锻模具、热挤压模具、压铸模具、热镦锻模具等。常用的热作模具钢有：中高含碳量的添加Cr、W、Mo、V等合金元素的合金模具钢;对特殊要求的热作模具钢，有时采用高合金奥氏体耐热模具钢制造。

Hot work die steel is mainly used to manufacture dies for pressure machining of workpieces under high temperature. Such as: hot forging die, hot extrusion die, die casting die, hot upsetting die, etc. The commonly used hot work die steels are: alloy die steels with medium and high carbon content and alloy elements such as Cr, W, Mo and V; Hot work die steel with special requirements is sometimes made of high alloy austenitic heat-resistant die steel.

三、塑料模具钢

3、 Plastic die steel

由于塑料的品种很多，对塑料制品的要求差别也很大，对制造塑料模具的材料也提出了各种不同的性能要求。所以，不少工业发达的已经形成了范围很广的塑料模具用钢系列。包括碳素结构钢、渗碳型塑料模具钢、预硬型塑料模具钢、时效硬化型塑料模具钢、耐蚀塑料模具钢、易切塑料模具钢、整体淬硬型塑料模具钢、马氏体时效钢以及镜面抛光用塑料模具钢等。

Because there are many kinds of plastics, the requirements for plastic products are also very different, and various performance requirements are put forward for the materials for manufacturing plastic molds. Therefore, many industrial developed countries have formed a wide range of steel series for plastic molds. Including carbon structural steel, carburized plastic mold steel, pre hardening plastic mold steel, age hardening plastic mold steel, corrosion-resistant plastic mold steel, easy cutting plastic mold steel, integral hardening plastic mold steel, maraging steel and plastic mold steel for mirror polishing.

四、无磁模具钢

4、 Non magnetic die steel

无磁模具钢是一种高锰钒系模具钢，在各种状态下都能保持稳定的奥氏体，具有非常低的导磁系数，高的硬度和强度，较好的耐磨性，较高适当的固溶加时效处理后，具有较好的综合性能。塑性好、韧性高、加工硬化倾向大、受热膨胀系数大、电阻率大、热导率低和磁性低等物理特性。在无磁建筑、无磁机械、选矿探矿设备及军事等领域有着广泛的应用。

Non magnetic die steel is a kind of high manganese vanadium die steel, which can maintain stable austenite in various states. It has very low magnetic conductivity, high hardness and strength, good wear resistance, and good comprehensive properties after appropriate solution and aging treatment. Good plasticity, high toughness, high work hardening tendency, high thermal expansion coefficient, high resistivity, low thermal conductivity and low magnetism. It is widely used in non-magnetic buildings, non-magnetic machinery, beneficiation and exploration equipment, military and other fields.
