Characteristics
Special CrMoV-alloyed hot work tool steel with excellent high-temperature strength and better
toughness properties than grade 2344 as well as higher thermal conductivity than the classic hot work
tool steels 2343, 2344 and 2367. In comparison to the NiCrMoV – tool steels 2711/2714 HIgh
PERformance DIE is characterized by higher wear resistance, comparable to grade 2343.

Applications

• Close-die forging: Small and medium-sized dies and die inserts for a large number of forgings. l
• Highly stressed plastic moulds: Small and medium moulds as well as mould inserts subject to abrasive stress caused by processing of thermosetting plastics, thermoplastics and composite materials also in combination with surface treatments.

      Where there is a requirement for
      – Polishability > 400 paper grit
      – Sensitive etch designs (e.g. HNO3)
      – Higher thermal conductivity
      we recommend grade Thruhard Supreme® l

• Light alloy processing: Gravity – as well as low pressure die – casting moulds and tools up to 45 HRC.
