H13 tool steel is chromium hot work tool steels which are widely used in hot and cold work tooling applications. H13 tool steel is classified as group H steels by the AISI classification system. This series of steels start from H1 to H19.

AISI H-13 tool steel is characterized by:

Good resistance to abrasion at both low and high temperatures
High level of toughness and ductility
Uniform and high level of machinability and polish ability
Good high-temperature strength and resistance to thermal fatigue
Excellent through-hardening properties
Very limited distortion during hardening

In steel H13, the molybdenum and vanadium act as strengthening agents. The chromium content assists die steel H-13 to resist softening when used at high temperatures. H-13 die steels offers an excellent combination of shock and abrasion resistance, and possesses good red hardness. It is capable of withstanding rapid cooling and resists premature heat checking. Tool Steel H13 has good machinability, good weldability, good ductility, and can be formed by conventional means.

Due to H13 tool steel excellent combination of high toughness and fatigue resistance, AISI H13 hot work tool steel is used more than any other tool steel in tooling applications.

Tool and die steel 1.2344 H13 Chemical composition

Tool and die steel 1.2344 H13  property

The hot work tool steel 1.2344 ESR has an improved material property due to the Electro-slag Remelting Process . Our ESR material is used when better material purity, particularly high tensile strength and compressive strength are required. Compared to the steel 1.2343 ESR, this material has a higher carbon content and is much harder and more wear-resistant. The material 1.2344 ESR is given a good tensile strength and toughness by the soft annealing.

1. Electro slag remelting ,annealing with high temperature diffusion process and ultra refinement treatment has food homogeneous microstructure and finer dispersed carbides .
2. Transverse/longitudinal≥0.8
3. Good tempering performance ,high toughness ,high remperature strength ,good thermal stability and thermal fatigue resistance. 
4. Annealing hardness≤230HB ,quenching hardness 51-55HRC ,tempering hardness 46-50HRC.
