Hot work tool steels maintain their hardness and strength at elevated temperatures, making them essential for die casting dies, hot forging dies, extrusion tools, and plastic injection molds. We supply H13, H11, SKD61, 4Cr5MoSiV1, and H21 grades. H13 is the most widely used hot work grade, offering excellent resistance to thermal fatigue, heat checking, and wear at temperatures up to 600°C. Available in forged blocks, round bars, and flat bars in annealed or pre-hardened conditions. ESR (Electroslag Remelted) quality available for demanding applications.
Overview of Hot Work Tool Steel Hot work tool steel is a specialized category of chromium-molybdenum-vanadium alloy steel engineered specifically for dies, tooling, and components that operate at elevated temperatures ranging from 300°C to over 700°C during service — conditions…
