A recommendation is made not to use an inner bend radius lower than the one indicated on the table in the technical datasheet.
For particularly severe work processes (double bending, bending with spindle axis parallel to milling direction, etc.), normalised material should be used where possible. For all other work processes, the same recommendation applies as for carbon steels of equivalent resistance.

A recommendation is made to heat at a temperature not higher than 1100°C and complete forming at a temperature not lower than 815°C. If forming has been performed correctly, subsequent cooling will not lead to any substantial hardening of the material and therefore no final thermal treatments are required.

It is easy to weld in all thicknesses using conventional welding techniques, including:
– shielded metal arc welding
– submerged arc welding
– gas-shielded arc welding

COR-TEN A:
A recommendation is made to use basic electrodes for shielded metal arc welding where particular mechanical resistance to welding is required, especially for the highest thicknesses.
COR-TEN B:
A recommendation is made to use basic electrodes for shielded metal arc welding; where submerged arc-welding or inert gas-welding are used, the same wire-flux combinations and the same protective gases may be used as for conventional structural carbon steels of equivalent resistance. Always make sure that the electrodes and flux are fully dry.
