H13 round bar is a representative alloy tool steel used in
hot work die steel and H13 hot work die steel. H13 die steel is basically the same as 9CrWMn die steel. The standard GB/T1299-2000 alloy tool steel is used. The H13 alloy tool steel is a steel type formed by adding alloying elements on the basis of carbon steel. At medium temperature (~600°), the comprehensive performance is good, the hardenability is high (hardening in air), the heat treatment deformation rate is low, and its performance and service life are higher than 3Cr2W8V. However, because of its high vanadium content, the medium temperature (600 degrees) performance is better than 4Cr5MoSiV steel.
H13 Round Bars Properties:
H13 round bar is the most widely used and most representative hot work die steel. Its main characteristics are:
(1) High hardenability and high toughness;
(2) Excellent resistance to thermal cracking, which can be water-cooled in the workplace;
(3) H13 round bar has medium abrasion resistance, and can also be used to improve the surface hardness of carburizing or nitriding, but slightly reduce the resistance to thermal cracking;
(4) Because of its low carbon content, the secondary hardening ability in tempering is poor;
(5) It has softening resistance at higher temperatures, but the hardness is higher than 540 °C (1000 °F), and the hardness is rapidly decreased (ie, the working temperature is 540 °C);
(6) The deformation of the heat treatment is small;
(7) Medium and high machinability;
(8) Medium resistance to decarburization. Even more noteworthy is that it can also be used to make important components in the aerospace industry.
