DIN 1.2343(X37CrMoV5-1）Hot Worked Mold Steel
H11/1.2343 tool steel is a high-strength, high-toughness hot-work mold steel with excellent heat resistance and hardness, widely used in manufacturing high-quality molds, mold components, and tools . Compared to other types of steel, H11 / 1.2343 tool steel exhibits superior comprehensive performance, especially at high temperatures, maintaining its strength and toughness even below 600℃ [High Temperature Performance]. Its chemical composition includes chromium, molybdenum, and vanadium, which contribute to its high hardness and wear resistance. While H11/1.2343 tool steel can undergo heat treatment processes like quenching and tempering to enhance its hardness and strength, it may impact its plasticity [Heat Treatment & Plasticity]. Overall, H11 /1.2343 steel is particularly suitable for manufacturing molds requiring high precision and complexity due to its superior deformation ability and workability [Suitability for Complex Molds] .

Principal Feature:
AISI H11 / 1.2343 Hot work tool steel is a 5% chromium hot work steel that is characterized by excellent impact toughness. It contains less vanadium than the widely-used H13 hot work tool steel. H11 /1.2343 is a deep-hardening, air-hardening steel that exhibits minimal size change during heat treatment. It has good resistance to thermal fatigue cracking (heat checking) and excellent resistance to gross cracking and thermal shock when water cooled in service. H11 /1.2343 is recommended for hot tooling applications where maximum resistance to cracking is required.
1.2343 Typical Application:
H11 / 1.2343 tool steel is typically applied in high-load hot work scenarios. It is well-suited for manufacturing high-speed hammer forging dies, aluminum and magnesium alloy hot forging dies, and black metal forging dies . Its applications also extend to hot work forging and extrusion dies, as well as helicopter rotor blades, where high toughness and hardness are required . The steel's excellent resistance to thermal fatigue, good hot hardness, and excellent machinability make it a preferred choice in these applications . To enhance its properties for longer life and higher design accuracy, H11 / 1.2343 steel can undergo various heat treatment processes .
1.2343 Heat Treatment:
