826M40 tubes available !


We have successfully cold drawn our first tubes in 826M40.
This is a surprising material in terms of work-hardening capabilities and complexity of the heat treatments required to refine its mechanical properties.
For this first batch of annealed tubes (+A), we obtained Rm=800MPa Re=700MPa and A%=24%.
We are now in the process of fine-tuning our heat treatments (quenching and tempering) in order to refine our panel of available mechanical characteristics.
