H-13 is an air-hardening, 5% chromium hot working die steel. It has high hardenability and resistance to thermal cracking ability, good comprehensive properties of high tempering stability.and toughness in hot condition. H-13 is an excellent choice for a wide range of hot work tooling applications, typical applications including extrusion tools, pressure die casting tools,, forging dies, hot shear blades, stamping dies, plastic molds and other wear-resisting parts.
