山東熱作模具鋼性能：

Properties of Shandong hot work die steel:

(1)硬度是模具鋼的主要技術指標。為了在高應力作用下保持模具的形狀和尺寸，它必須具有足夠高的硬度。冷作模具鋼的硬度在常溫下一般保持在HRC60左右，熱作模具鋼根據其工作條件一般要求保持在HRC40～55的范圍內。對于同一鋼種，在一定的硬度值范圍內，硬度與變形抗力成正比；但是，硬度值相同但成分和結構不同的鋼種之間的塑性變形抗力可能存在顯著差異。

(1) Hardness is the main technical index of die steel. In order to maintain the shape and size of the mold under high stress, it must have sufficient hardness. The hardness of cold working die steel is generally maintained at about HRC60 at room temperature, and hot working die steel is generally required to be maintained within the range of hrc40 ~ 55 according to its working conditions. For the same steel, within a certain range of hardness value, the hardness is directly proportional to the deformation resistance; However, there may be significant differences in plastic deformation resistance between steel grades with the same hardness value but different composition and structure.

(2)紅硬性在高溫下工作的熱作模具，要求保持其組織和性能的穩定性，以保持足夠高的硬度。這種性能稱為紅硬性。碳素工具鋼和低合金工具鋼通常在180-250℃溫度范圍內能保持這種性能，而鉻鉬熱作模具鋼一般在550-600℃溫度范圍內能保持這種性能。鋼的紅硬性主要取決于鋼的化學成分和熱處理工藝。

(2) The hot working die with red hardness working at high temperature requires to maintain the stability of its structure and performance in order to maintain a sufficiently high hardness. This property is called red hardness. Carbon tool steel and low alloy tool steel can maintain this property in the temperature range of 180-250 ℃, while chromium molybdenum hot work die steel can maintain this property in the temperature range of 550-600 ℃. The red hardness of steel mainly depends on the chemical composition and heat treatment process of steel.

山東熱作模具鋼的使用壽命

Service life of Shandong hot working die steel

決定模具使用壽命的重要因素往往是模具材料的耐磨性。模具在工作中要承受相當大的壓應力和摩擦力，這就要求模具在強烈的摩擦力下仍能保持其尺寸精度。模具的磨損主要有機械磨損、氧化磨損和熔合磨損三種。為了提高模具鋼的耐磨性，既要保持模具鋼的高硬度，又要保證鋼中碳化物或其他硬化相的成分、形貌和分布合理。

The wear resistance of die materials is often an important factor that determines the service life of dies. The die has to bear considerable compressive stress and friction in its work, which requires the die to maintain its dimensional accuracy under strong friction. Die wear mainly includes mechanical wear, oxidation wear and fusion wear. In order to improve the wear resistance of die steel, it is necessary to maintain the high hardness of die steel and ensure the reasonable composition, morphology and distribution of carbides or other hardened phases in the steel.

對于在重載和高速磨損工況下使用的模具，要求模具鋼表面能形成一層薄而致密、附著力好的氧化膜，保持潤滑，減少模具之間的粘連、熔接等熔合磨損。和工件。可減少模具表面氧化造成的氧化磨損。因此，模具的工作條件對鋼材的磨損影響很大。

For the dies used under heavy load and high-speed wear conditions, it is required that a thin and dense oxide film with good adhesion can be formed on the surface of the die steel to maintain lubrication and reduce the fusion wear such as adhesion and fusion between the dies. And workpiece. It can reduce the oxidation wear caused by the oxidation of the mold surface. Therefore, the working conditions of the die have a great impact on the wear of steel.
