| Steel properties |
Chromium-molybdenum alloy steel with 1% of vanadium with high red strength. This steel is suitable for vacuum hardening and suface treatments such as nitriding, PVD treatment (titanium nitrides), etc.
Produced as EFS SUPRA ( vacuum arc or electro-slag remelted) this steel is guaranteed to give a high mirror polish. It is suitable for vacuum hardening and surface treatments such as nitriding, titanium nitrieds, etc. |
| |
| Applications |
Pressure casting moulds, hot extrusion tools, press dies, die inserts, moulds, extruder screws and sleeves for working plastics.
Produced as EFS SUPRA ( vacuum arc or electro-slag remelted): forging dies, inserts for injecting plastic materials requiring high polish, inserts and moulds for pressure casting of light alloys. |
