Repairing of NITRIDED barrels is made by:
| Inner diameter in mm | 25 ¸ 500 |
| Outer diameter (max.) in mm | 950 |
| Lenght (max.) in mm | 6000 |
| Depth of nitrided layer in mm | 0.5 ¸0.6 |
| Hardness of nitrided layer | 950 ± 80 HV |
Refurbishment of BIMETALLIC barrels is made by grinding or honing of the inner diameter, so that the inner diameter of the barrel is unified.
