Introduction Hot Working Tool Steel(1.2740)

Hot working steels are a group of steel used to cut or shape material at high temperatures. H-group tool steels were developed for strength and hardness during prolonged exposure to elevated temperatures. These tool steels are low carbon and moderate to high alloy that provide good hot hardness and toughness and fair wear resistance due to a substantial amount of carbide. H1 to H19 are based on a chromium content of 5%; H20 to H39 are based on a tungsten content of 9-18% and a chromium content of 3–4%; H40 to H59 are molybdenum based.

The hot working tool steel consists of three kinds of hammer forging die, hot extrusion die and die casting die. As mentioned earlier, the main feature of the working condition of the hot die is to contact with the hot metal, which is the main difference from the working conditions of the cold working die.

Characteristic (1.2740)

The metal in the surface of the mold cavity is heated. Usually, when the hammer forging dies work, the surface temperature of the die cavity can reach 300~400 degrees or more, and the hot extrusion die can reach 500 or 800 degrees or more. The temperature of the die cavity is related to the type and pouring temperature of the die casting material. As for the die casting black metal, the mold cavity temperature can reach more than 1000 degrees centigrade. This high temperature can reduce the hardness and strength of the cavity surface significantly, and easily occur during the use. Therefore, the basic performance requirement of hot die steel is high thermoplastic resistance, including high temperature hardness, high temperature strength and high thermoplastic resistance. In fact, it reflects the high tempering stability of steel. Therefore, the first way to alloying hot die steel can be found, that is, adding Cr, W, Si. and other alloy elements can improve the tempering stability of the steel.
