Hot Work Mold Steel

 


Hot work mold steel refers to alloy tool steel suitable for making molds for thermal deformation processing of metals, such as hot forging molds, hot extrusion molds, mold-casting molds, hot heading molds, etc. Since hot work molds work under high temperature and high-pressure conditions for a long time, mold materials are required to have high strength, hardness and thermal stability, especially high thermal strength, thermal fatigue, toughness and wear resistance.

 

 

There are many classification methods for hot work mold steel, which can be classified according to the content of alloying elements and the performance after heat treatment, and can be classified according to the purpose or alloying elements.

 

1. According to the application, it can be divided into steel for hot forging mold, steel for hot extrusion mold, steel for mold casting mold and steel for hot punching mold.

 

2. According to heat resistance, it can be divided into low heat-resistant steel (350-370°C), medium heat-resistant steel (550-600°C), and high heat-resistant steel.

 

3. According to the unique properties, it can be divided into high toughness hot work mold steel, high heat strength hot work mold steel, and high wear resistance hot work mold steel.

 

4. According to the classification of alloy elements, it can be divided into low alloy hot work mold steel (tungsten, chromium and molybdenum), medium alloy hot work mold steel and high alloy hot work mold steel (tungsten molybdenum series and chromium molybdenum series); or Divided into tungsten-based hot mold steel, chromium-based hot mold steel and chrome-tungsten-molybdenum-based hot mold steel. The high-temperature strength and thermal stability of chromium-tungsten high-alloy hot work mold steel are not as good as those of the tungsten-molybdenum series, but the cold and hot fatigue resistance and toughness are higher than those of the tungsten-molybdenum series

 

 

Hot work steels should have the following physical characteristics:

1. Resistance to deformation at the working temperature.

2. Resistance to shock.

3. Resistance to wear at the working temperature.

4. Resistance to heat-treating deformation.

5. Resistance to heat checking.

6. Good machinability in the annealed condition.
