(I have left our Mr Ron in this internal discussion)
Please review EN 10083 as regards to Q&T bars of these 2 grades .
Did we ask for induction hardening ?
Does it also refer to the related EN regarding delivery condition?
What is our PO regarding crack ? Is there a statement on distortion and crack?
Even if crack can happens at the head only, how much do we need to cut
off the head to ensure that there is no crack on the rest of the bar?
