HMoD, steel for hot work applications, highlights its high resistance to hot wear with maximum resistance to deformation at high temperatures, its balanced chemical composition of carbon, cobalt, chromium and molybdenum, is ideal for tool and hot components where their properties are crucial for high performance tools.
HMoD (ESR Technology) It is a Hot Work steel specifically designed for applications in tools and components where hot wear resistance is critical, its balanced chemical composition, represented by its DIN 1.2889 equivalence (X45CoCrMoV5-5-3), includes elements such as carbon, chromium, molybdenum, vanadium and cobalt, this combination gives HMoD exceptional properties that make it stand out in hot working environments.
Maximum resistance to deformation at high temperatures.
High resistance to tempering.
High resistance to wear at high temperatures.
Applications: The HMoD is a solution for a variety of hot application tooling, including: • Extrusion dies for copper alloys.
Copper alloy die casting mold inserts.
Cores or inserts in die-cast aluminum alloy casting systems (HPDC).
Inserts in hot stamping tooling in transition areas.
Inserts in warm extrusion dies for steels.
Heat treatment: The HMoD is subjected to heat treatment to optimize its properties, including:
Elimination of stresses for tools subjected to severe roughing by machining.
Hardening through austenitization, quenching and triple tempering to achieve the desired hardness.
Nitriding is a thermochemical treatment recommended to generate a hard and wear-resistant surface layer. It is advisable to temper it before nitriding to prevent risks such as cracking or detachment of the nitrided layer. In summary, HMoD is an outstanding choice for those seeking a hot work steel with exceptional wear resistance properties and minimal deformation under extreme conditions.
