Plastic mould steel with good machinability properties
The very best machinability, high compressive loads
40 CrMnMo 6-8
As-supplied condition: quenchend and tempered to a hardness of 280 to 325 HB (950 – 1100 N/mm²)
General fields of application: Plastic moulds, for which the main requirement is for machinability, mould frames and mould plates, mould frames for plastic and die casting moulds
ES Aktuell S can be nitrided to improve its wear resistance. ES Aktuell S is not suitable for graining or polishing. For this we recommend ES Aktuell EST, Mat.-No. 1.2311. For material cross sections over 400 mm we recommend ES Aktuell 1000 or ES Aktuell 1200 for better full quenching and tempering.
