hot forging die steel Product Introduction
Main characteristics of mold steel: oil and gas quenching die steel with good hardenability; good resilience; suitable for surface treatment; good polishing properties.
When the hot forging die is in use, the heating temperature of the processing object is higher than about 1200 ℃, in addition to thermal cracking, high-temperature wear is also more serious. In addition, the hot extrusion die, which is mostly used for forming aluminum products, its main form of damage is due to sliding wear and deformation caused by contact with the forming blank.
