 Abrasive steel 

 Mold steel is used to make Die, forging and molding mold mold steel. The mold is the main processing tools for manufacturing parts in machinery manufacturing, radio instruments, motors, appliances and other industrial sectors. The quality of the mold directly affects the quality of the pressure process, the accuracy of product yield and production costs, quality and service life of the mold in addition to relying on the structural design and machining accuracy, mainly due to the impact of mold materials and heat treatment. 

 Mold steel 
 Die steel can be broadly divided into (cold work die steel), (hot work die steel) and (plastic mold steel), used for forging, stamping, cutting type, die-casting. A variety of molds for different purposes, the complexity of the working conditions, mold steel, the manufacture of the mold according to their working conditions, should have high hardness, strength, abrasion resistance and sufficient toughness, and high hardenability, quenching hard and the other process performance. Such uses, working conditions and complex, so the performance requirements of the mold steel. Cold Working Die Die, drawing die, drawing die, pressure die thread rolling die, roll silk panels, cold heading die, and cold extrusion die and so on. Cold-working die steel, the working conditions of its manufacture with a high hardness, strength, wear resistance, sufficient toughness, and high hardenability, hardened, and other process performance. Alloy tool steel used for these purposes are generally high-carbon alloy steel, carbon content above 0.80%, chromium is an important alloying elements of the type of steel, its mass fraction is usually not more than 5%. Demanding but for some of the wear resistance, the deformation is small mold steel after quenching, the highest chromium mass fraction of 13%, and for the formation of a large number of carbides in the steel carbon content is also high, up 2.0 percent ~~ 2.3%. Cold work die steel, high carbon content, the organization belonged to the eutectoid steel or ledeburite. Commonly used class of steel high-carbon low-alloy steel, high carbon high chromium steel, chromium molybdenum steel, carbon, chromium tungsten Kushiro steel and so on. Hot work die is divided into hammer forging, die forging, extrusion and die-casting of several main types, including hot forging dies, presses, forging dies, die stamping, hot extrusion mold and metal die-casting mold. Thermal deformation of the mold at work in addition to withstand mechanical stress, but also withstand repeated heating and cooling do cause a lot of heat stress. Hot work die steel should have high hardness, strength, red hardness, wear resistance and toughness, but also has good high temperature strength, thermal fatigue stability, thermal conductivity and corrosion resistance are also required to have a high hardenability to ensure that the entire section has consistent mechanical properties. For the die-casting mold steel, but also the surface layer after repeated heating and cooling cracks, as well as to withstand liquid mold steel 
 The impact of state metal flow and erosion performance. Type of steel is generally a medium carbon alloy steel, carbon mass fraction of 0.30% and 0.60% belong to sub-eutectoid steel, also part of the steel due to join the more alloying elements (such as tungsten, molybdenum, vanadium, etc.) and eutectoid Guo eutectoid steel. Commonly used class of steel chrome-manganese steel, chrome-nickel steel, chromium and tungsten steel. Plastic molds thermoplastic molds and thermoset plastic mold. Plastic mold steel has a certain strength, hardness, wear resistance, thermal stability and corrosion resistance performance. It also requires a good process, such as heat treating smaller, good processing properties and good corrosion resistance, grinding and polishing performance, good welding performance, high roughness, thermal conductivity and the size and shape of the stability of the working conditions . Under normal circumstances, the injection molding or extrusion die can be used hot work die steel; thermosetting molding and requiring high wear, high strength mold can be used to cold work die steel.
