Features
H13 is a hot work die steel, which is formed by adding alloying elements on the basis of carbon steel, implementing the standard GB/T1299-2014. Unified digital code T23353; Grade 4Cr5MoSiV1. At medium temperature (~600°), the overall performance is good, the hardenability is high (can be hardened in the air), the heat treatment deformation rate is low, and the performance and service life are higher than 3Cr2W8V.
H13 steel is the most widely used and most representative hot work die steel, its main characteristics are:
(1) With high hardenability and high toughness;
(2) Excellent thermal cracking resistance, which can be water-cooled in the workplace;
(3) has medium wear resistance, can also use carburizing or nitriding process to improve its surface hardness, but slightly to reduce the thermal cracking resistance;
(4) Due to its low carbon content, the secondary hardening ability in tempering is poor;
(5) It has the ability to resist softening at higher temperatures, but the hardness decreases rapidly when the temperature is higher than 540 ° C (1000 ° F) (that is, the working temperature of the ability is 540 ° C);
(6) Small deformation of heat treatment;
(7) Medium and high machinability;
(8) Medium resistance to decarbonization.
