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 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.

在模具生产成本中，材料费用一般占10%~20%，而机械加工、热处理、装配和管理费用占80%以上，所以模具材料的工艺性能是影响模具的生产成本和制造难易的主要因素之一。

In the mold production cost, the material cost generally accounts for 10% ~ 20%, while the machining, heat treatment, assembly and management costs account for more than 80%, so the process performance of mold material is one of the main factors affecting the mold production cost and manufacturing difficulty.

为了便于生产，要求模具钢淬火温度范围尽可能放宽一些，济南模具钢特别是当模具采用火焰加热局部淬火时，有口皆碑济南模具钢由于难于准确地测量和控制温度，济南模具钢就要求模具钢有更宽的淬火温度范围。

In order to facilitate production, it is required that the quenching temperature range of die steel should be broadened as much as possible. Jinan die steel, especially when the die is partially quenched by flame heating, is well-known. Because it is difficult to accurately measure and control the temperature, Jinan die steel requires a wider quenching temperature range.

模具在热处理时，尤其是在淬火过程中，s136模具钢要产生体积变化、形状翘曲、畸变等，为保证模具质量，济南模具钢要求模具钢的热处理变形小，特别是对于形状复杂的精密模具，淬火后难以修整，对于热处理变形程度的要求更为苛刻，模具钢材型号大全济南模具钢应该选用微变形模具钢制造。

During the heat treatment of the die, especially in the quenching process, S136 die steel has to produce volume change, shape warping, distortion, etc. in order to ensure the quality of the die, Jinan die steel requires that the heat treatment deformation of the die steel is small, especially for the precision die with complex shape, it is difficult to repair after quenching, and the requirements for the degree of heat treatment deformation are more stringent The tool steel should be made of micro deformation die steel.

在选择模具钢时，除了必须考虑使用性能和工艺性能之外，济南模具钢还必须考虑模具钢的通用性和钢材的。模具钢一般用量不大，模具材料p20为了便于备料，模具钢材型号大全济南模具钢应尽可能地考虑钢的通用性，尽量利用大量生产的通用型模具钢，5crnimo模具钢以便于采购、备料和材料管理。另外还必须从经济上进行综合分析，h13材料考虑模具的制造费用、工件的生产批量和分摊到每一个工件上的模具费用。从技术、经济方面分析，济南模具钢以终选定合理的模具材料。

In the selection of die steel, in addition to the use performance and process performance, Jinan die steel must also consider the universality of die steel and the price of steel. Generally, the consumption of die steel is not large. In order to facilitate the material preparation, the die steel model is complete. Jinan die steel should consider the universality of steel as much as possible, and make full use of the mass-produced general die steel and 5CrNiMo die steel to facilitate the purchase, material preparation and material management. In addition, we must make a comprehensive economic analysis. The price of H13 material takes into account the manufacturing cost of the mold, the production batch of the workpiece and the mold cost allocated to each workpiece. From the technical and economic aspects of comprehensive analysis, Jinan die steel to finally select a reasonable die material.
