Characteristics and main uses of H13 die steel
Whether it is mechanical parts or daily necessities, most of them are made by molds, which shows the importance of mold steel. In the gradual development of mold steel, in order to adapt to the development of the market, there are also many types, and H13 is one of them.
H13 steel is the most widely used and most representative hot work die steel. Its main characteristics are:
(1) It has high hardenability and high toughness;
(2) Excellent thermal crack resistance, can be water-cooled in the workplace;
(3) With moderate wear resistance, carburizing or nitriding process can also be used to improve its surface hardness, but the thermal crack resistance should be slightly reduced;
(4) Due to its low carbon content, the secondary hardening ability in tempering is poor;
(5) It has softening resistance at higher temperatures, but the hardness decreases rapidly when the operating temperature is higher than 540°C (1000°F) (that is, the working temperature is 540°C);
(6) The deformation of heat treatment is small;
(7) Medium and high machinability;
(8) Moderate decarburization resistance.
Having said so much about the main characteristics of H13 die steel, do you know where H13 die steel is used? More notably, it can also be used to make important components in the aviation industry.
The use is basically the same as that of 9CRWMN die steel, but because of its higher vanadium content, the performance at medium temperature (600 degrees) is better than that of 4Cr5MoSiV steel. It is a representative steel grade that is widely used in hot work die steel.
H13 die steel is used to manufacture forging dies with large impact load, hot extrusion dies, precision forging dies; aluminum, copper and its alloy die-casting dies.
