DIN 1.2367 steel stands out from traditional high-temperature hot work steels like H13 due to its high molybdenum content, which significantly enhances its performance under continuous high-temperature conditions. This unique composition provides superior thermal fatigue resistance and wear performance, making it especially suitable for demanding hot work applications.
As a versatile and economical special tool steel, 1.2367 offers a balanced combination of high strength, hardness, and good toughness. Its excellent wear resistance and thermal fatigue properties ensure long service life even in harsh working environments.
Typically supplied in an annealed state with a hardness of ≤235 HBW, DIN 1.2367/X38CrMoV5-3 steel allows for better machinability and cutting performance during processing, making it an ideal choice for manufacturing hot forging dies, die casting molds, extrusion tools, and other hot work tooling.

Soft Annealing
Temperature: 780-800°C
Holding time: 2-4 hours (cool down in furnace to 500°C)
Target hardness: ≤229 HB
Microstructure: spheroidal carbides with spheroidization rate ≥90%
Quenching
Preheat temperature: 650°C, hold for 30 minutes
Quenching temperature: 1020-1030°C, hold for 30 minutes + 6 minutes per cm thickness
Cooling medium: high-speed nitrogen (≥5 bar) or staged oil quenching
Key control: Temperatures above 1030°C cause grain growth; below 1020°C result in insufficient Mo2C dissolution
Tempering
First stage: 550°C for 2 hours to relieve quenching stress
Second stage: 600-620°C for 2 hours, repeat twice for core hardening
At 550°C, hardness reaches a minimum (~46-48 HRC)
At 600°C hardness peaks (~50-52 HRC)
At 620°C hardness remains stable (~48-50 HRC)
