1. Used in hot forging die

Hot forging die is generally working under harsh conditions, to withstand the role of high temperature and high pressure, and some are also subject to greater impact, it requires hot forging die has a high temperature strength, thermal fatigue properties and impact toughness. The H13 steel high temperature strength, hardness and good impact resistance, it is the hot forging die most in need. 80s of last century, Europe and the United States and Japan and other countries, H13 steel used for hammer forging, friction press forging die, hot forging press forging die and other hot forging die has been quite common. Since the beginning of 1990s in our country, some large-scale machinery manufacturers have used H13 steel forged gears, high speed hammer forging blades and ordinary small and medium-sized forging dies, and have received satisfactory results. Such as a company designed roller mold H13 steel instead of 5CrNiMo material, its production increased nearly doubled.

2. Used in hot extrusion die

For a long time, 3Cr2W8V steel has been used in the extrusion dies used in the hot extrusion processing of auto parts, aluminum profiles and military equipment, but due to the hot extrusion die working under the condition of hot and cold, Severe intracavity flow friction, the mold to withstand higher temperatures and the unit pressure, with hot extrusion mold 3Cr2W8V prone to thermal fatigue cracks, resulting in low life expectancy, a direct impact on product quality and cost. Despite the reasonable forging process, the mold has been toughening heat treatment or surface strengthening and improve the service life of the mold, but the increase of mold life is limited, and its economic benefits brought about by the change is not significant. However, the high temperature strength and hardness of H13 steel can avoid the premature deformation and cracking of the hot extrusion die, and the good wear resistance can also reduce the wear on the mold surface. Therefore, in the early 1990s, H13 Steel for hot extrusion die.

At present, the vast majority of aluminum manufacturers in China use H13 steel to make hot extrusion dies, and the extruded aluminum surfaces have been improved in surface quality and the service life of molds has also nearly tripled. Hunan Province, a group of companies through the comparison of field production tests show that under the same conditions, the service life of H13 steel mold 3Cr2W8V mold 2 to 3 times higher, and does not occur sharp crack, wear resistance, working with the groove shallow, Less pitting.

3. Used in non-ferrous metal die casting

During the die-casting process, the molten metal is injected into the mold cavity at a certain frequency and speed, and the mold surface repeatedly flushes with intense friction to withstand high temperature, high pressure and strong thermal shock. This requires die-casting mold materials in the thermal shock conditions have sufficient hardness, thermal expansion coefficient, good thermal conductivity, and has high erosion resistance and fatigue resistance. Compared with the 3Cr2W8V, H13 steel thermal fatigue resistance and anti-erosion effect obvious advantages. At present, in addition to copper alloys, aluminum, magnesium and zinc and other non-ferrous metal die-casting molds are mostly used H13 steel.
