Hot die tool steel is one of steel which is used to manufacture tools. Actually, there are many hot die tool steels in the market and the good thing with all of them is that they can be used for manufacturing tools in technical industries. It is used in various methods of shaping metals which includes stamping, extrusion, drawing, piercing and so forth. Find the best hot die tool steel if you need.
Tool made of hot die tool steel has enough hardness after heat treatment, as for metal cutting the HRC of tools is generally 60 above. Under high cutting speed and high temperature heat condition produced by the hard materials processing, hot die tool steel can still keep high hardness. Hot die tool steel has good resistance to wear, namely the ability of abrasion resistance. Under great pressure and friction condition, hot die tool steel can still keep its shape and size unchanged. Hot die tool steel has some of the strength and toughness, and this makes the tool made of hot die tool steel in the work can bear a heavy load, impact and vibration and the bending stress of the complex to ensure the normal use of tools. Because all the tools will be applied to different working conditions, the hot die tool steel also has some other performance, such as mould steel should also has some of the high temperature mechanical properties, thermal fatigue, thermal conductivity and wear-resisting corrosion resistance, etc.
In addition to its usability, the hot die tool steels also have good technological properties. Hot die tool steel should have good thermal pressure processing quality and machining performance to guarantee the production and use of tools. The steel processing depends on the quality of chemical composition. Hot die tool steel quenching temperature should be wide enough to reduce the possibility of overheating. Hardenability means the highest performance of hardness that steel can reach after quenching. Hardenability has something to do with the chemical composition of the carbon steel, especially the content, the higher carbon content, the higher the hardenability. Its quenching degree means hardness distribution of hardened steel from the surface to the inner. Its quenching degree depends on the chemical composition, pureness and the grain degrees of steel.
As the hot die tool steel will be used in the manufacturing of different tools, there are certain requirements to the two kinds of performance. Once decarburization happens on the surface, it will lower surface hardness, therefore, the high quality hot die tool steel decarburization sensitivity must be low. In the same conditions, steel decarburization sensitivity depends on its chemical composition. During heat treatment, the size and shape of the hot die tool steel must be stable. For the hot die tool steel which is used to manufacture cutter and measuring implement, grindability is demanded. Chemical composition of the hot die tool steel will determine the grindability, especially vanadium content, if vanadium quality score is not less than 0.50% of the grindability will not be good enough.
