Characteristics of ASTM H13 Alloy Tool Steel Bars

Characteristics of ASTM H13 Alloy Tool Steel Bars:
Excellent Thermal Fatigue Resistance: H13 steel maintains high strength and stability at elevated temperatures, enabling it to resist thermal fatigue cracking (heat checking). This characteristic makes it outstanding in hot work die applications, such as die-casting molds and hot extrusion dies, allowing it to withstand repeated heating and cooling cycles.

Good Wear Resistance: After heat treatment, H13 steel exhibits high hardness and wear resistance, enabling it to resist wear and erosion to a certain extent, thereby extending the service life of molds.

Superior Machinability: H13 steel is easy to cut and polish, with minimal deformation during heat treatment, making it suitable for manufacturing high-precision, long-life molds and tools.

Heat Crack Resistance: H13 steel is less prone to developing thermal cracks at high temperatures, making it suitable for manufacturing molds and tools that operate in high-temperature environments.
