H13 Hot Work Die Casting Mould Steel Plate High Temperature Resistant for Aluminum and Zinc Die Casting Moulds

H13 hot work die casting mould steel plate is the most widely used hot work mould steel globally, renowned for its outstanding high-temperature strength, thermal fatigue resistance, and toughness, making it the standard material for aluminum, zinc, and magnesium die casting moulds. Die casting moulds operate under extreme cyclic heating and cooling conditions, and H13 die casting mould steel plate is specially designed to withstand such harsh environments without cracking, deforming, or wearing rapidly. Its balanced alloy composition of chromium, molybdenum, and vanadium improves hardenability, high-temperature hardness, and resistance to heat checking, ensuring a long service life for die casting moulds.
Our H13 die casting mould steel plate is produced through electric furnace smelting and optional electroslag remelting, ensuring high purity, uniform structure, and reduced internal defects. Strict rolling and annealing processes refine grain size and improve machinability, allowing for efficient mould cavity machining. After proper quenching and tempering, H13 die casting mould steel plate reaches a hardness of 48–52 HRC, maintaining excellent hardness and toughness at elevated temperatures during continuous die casting operations. This stability prevents mould cracking and extends service life, significantly reducing production costs for die casting manufacturers.
Available in thicknesses from 8mm to 300mm, our H13 die casting mould steel plate caters to various die casting mould components, including mould cores, cavities, inserts, slides, and ejector pins. The material exhibits excellent welding performance and repair capabilities, allowing mould maintenance without structural damage. We provide customized cutting, precision grinding, and rough machining services to meet customer drawing requirements. For manufacturers in the die casting industry, H13 die casting mould steel plate remains the most reliable and cost-effective choice, delivering consistent performance, high temperature resistance, and extended mould life under heavy production conditions.
