What are the functions of hot die steel?

Hot forging die steel with HMAX new high temperature resistant high patience die steel, steel, cold hot amphibious matrix substrate purity, uniform annealing organization, in all directions has good patience and ductility, good abrasion resistance, excellent heat treatment standard stability, good hardenability, excellent resistance to tempering softening function, excellent high temperature strength, good thermal fatigue resistance, polishing, high hardness, high wear resistance and high patience. Hot forging die steel manufacturers take you to learn more!

Hot die steel refers to alloy tool steel suitable for hot deformation processing of difficult metal, such as hot forging die, hot extrusion die, die-casting die, hot heading die, etc. Because the hot die is working under high temperature and high pressure for a long time, it is required that the die data have high strength, hardness and thermal stability, especially high thermal strength, thermal fatigue, endurance and wear resistance.

High temperature strength and excellent endurance. Hot die, especially hot forging die, work under a great impact, and the impact frequency is very high, assuming that the die does not have high strength and excellent tolerance, a brief cracking.

Excellent wear-resisting function, because the hot die buting in addition to be deformed by blank friction wear, but also by high temperature oxidation corrosion and iron oxide scrap grinding, so the demand for hot die steel has higher hardness and adhesion.

There are many classification methods for hot die steel, which can be classified according to the content of alloying elements and the function after heat treatment, according to the usage, or according to alloying elements.

According to the use can be divided into hot forging die steel, hot extrusion die steel, die casting die steel, hot blanking die steel.

According to the heat resistance can be divided into low heat resistance steel (350 ~ 370℃), medium heat resistance steel (550 ~ 600℃), high heat resistance steel.

According to the function is divided into high endurance hot die steel, high heat strength hot die steel, high wear resistance hot die steel.
