Product features
  • 40 CrMnNiMo 8-6-4
  • As-supplied condition: quenched and tempered to a hardness of 280 to 325 HB (950-1100 N/mm²)
  • General fields of application: Mould steel for plastic moulds with plate thicknesses of approx. 400 mm upwards if uniform hardness, increased toughness and polishability are required, even in the base of the mould. Moulds for television casings and backs, copier bodies, bumper moulds, moulds for dashboards and large external car body parts, waste container moulds, die casting frames.
  • ES Aktuell 1000 – a tool steel designed for the largest plastic moulds. The additional 1% nickel content considerably improves full thickness heat treatability compared with material 1.2311. Preworking the mould in the annealed condition followed by hardening and tempering after rough machining is not required.
