| 1) Remark: Steel C40R is suitable for slightly higher loaded parts in vehicle, engine and machine engineering with enhanced workability at constant mechanical qualities (e.g. transmission parts, crank shafts, cylinder). As a bright steel product it is used in the form of bars, bright, straight, in various conditions (see DIN EN 10277 : 1999-10). |
