Despite their very high level of hardness, XAR 400, XAR 450 and XAR 500 steels are suitable for bending. However, it is recommended that the bending process is performed slowly and perpendicularly to the milling direction. Deburring of pieces and pre-heating of oxy-fuel cut edges is also useful (120 ÷ 200°C). Provided machines delivering the appropriate power and suitable tools are used, additional mechanical engineering work, such as boring, countersinking, etc. may be performed.
