- EN 10085: 2001 Nitriding steel. Technical delivery conditions
- EN 10250-3: 2000 Open steel die forgings for general engineering purposes. Alloy special steels
- 40CrMoV13-9 is the EN chemical designation. It has a fairly low thermal conductivity among EN wrought alloy steels. In addition, it has a very high embodied energy and a fairly high base cost.
- Moulds for manufacturing plastic materials.
- suitable for chemical graining.
- Die blocks and punches.
- Prototype dies for light alloy pressure casting.
