Processing information

Cutting

All kind of flame cutting processes can be used.

Bending

In order to optimize this operation, a minimum temperature of 10 °C is requested.

Internal minimum radius V block opening minimum
Transversal 4 × th 14 × th
Longitudinal 5 × th 14 × th

Rolling

Minimum internal diameter 40 × th.

Welding

Hardness is obtained directly during the rolling process, thermo-mechanical rolling process. This type of process requests an addition alloy elements. Therefore the CEV value explains the strict necessity to fully respect the welding process. No preheating is required, nevertheless, in case of classical welding GMAW, the heat input must be managed correctly in order to avoid too much stress or distortion (Indicative Energy = 1.5 up to 2 kJ/mm).
