Die steel is used to make cold stamping die, hot forging die, die casting die and other steel. Mold is the main processing tool for manufacturing parts in mechanical manufacturing, radio instruments, motors, electrical appliances and other industrial sectors. The quality of the mold directly affects the quality of the pressure processing technology, the precision of the product, the output and the production cost. The quality and service life of the mold are mainly affected by the mold material and heat treatment besides the reasonable structure design and processing precision.

模具钢的分类及常见分类

Classification and common classification of die steel

用于制造模具的钢从生产工艺（即冶炼流程）上通常可分为电炉钢和电渣钢。电渣钢（ESR）的生产，是将电炉钢进行再次电渣重融精炼。

The steel used for mould manufacturing can be divided into electric furnace steel and electroslag steel from the production process (i.e. smelting process). Electroslag steel (ESR) is produced by remelting EAF steel.

从功能上讲任何钢种都能用做模具钢；狭义讲的模具钢还是指用于模具制造的特种钢。钢研海德目前只生产电渣钢。电炉钢一般为满足低端模具生产需求。

Functionally, any kind of steel can be used as die steel; In a narrow sense, die steel refers to special steel used in die manufacturing. At present, Gangyan Haide only produces electroslag steel. EAF steel is generally used to meet the needs of low-end mold production.

目前一些进口产品生产企业，如日本山阳、高周波、瑞典一胜百、德国葛利兹、德国思慕等企业即供应电炉钢也供应电渣钢。

At present, some manufacturers of imported products, such as Japan's Shanyang, gaozhoubo, Sweden's yishengbai, Germany's glitz and Germany's Simo, supply both EAF steel and ESR steel.

从模具工作温度及用途来分，一般模具将分为：热作模具钢、塑胶模具钢、冷作模具刚等三大类。每个品类的钢种都非常多，咱们市面上见得多谈的多的常用钢种，是因为其综合性能、、热处理工艺等方面为使用者广为接受，才流行的。

From the working temperature and purpose of the mold, the general mold will be divided into three categories: hot work mold steel, plastic mold steel, cold work mold steel. There are many kinds of steel in each category. The common steel that we see and talk about in the market is popular because its comprehensive performance, price, heat treatment process and other aspects are widely accepted by users.

由于各种模具用途不同，工作条件复杂，因此对模具用钢，按其所制造模、强度、耐磨性，足够的韧性，以及高的淬透性、淬硬性和其他工艺性能。由于这类用途不同，工作条件复杂，因此对模具用钢的性能要求也不同。

Due to the different uses of various dies and complex working conditions, the die steel should be manufactured according to its die, strength, wear resistance, sufficient toughness, high hardenability, hardenability and other technological properties. Due to different uses and complex working conditions, the performance requirements of die steel are also different.
