Standard analysis:
| C | Si | Mn | Cr | Ni | S |
| 0,3 | 0,5 | 1,0 | 16,0 | 0,3 | 0,1 in % |
Heat treatment data:
Soft annealing: 850 – 880 °C
Stress-relief annealing: max. 480 °C
Delivery condition: tempered and hardened
Stress-relief annealing is recommended in case of more than 30% machining of the part prior to the final processing
