Description of H13 Tool Round Bar
H13 Tool Steel is used to manufacture forging die with large impact load, hot extrusion dies, precision forging dies; aluminum, copper and its alloy die-casting die. H13 has superior machinability and polishing properties, high toughness and high plasticity, high wear resistance at high temperatures, excellent overall hardenability, and good high-temperature strength and thermal fatigue resistance. At the same time, H13 has a small deformation during heat treatment, and a tendency to generate an iron oxide scale during air quenching is small.
