CharacteristicsSpecial 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 worktool 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 l 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 incombination with surface treatments.

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

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

Delivered conditionAnnealed to max. 250 HBQuenched and tempered to customer specifi cation on requestto max. 430 HB (� approx. 1450 MPa)*Sizes upon request
