Can 42CrMo and Q345B be quenched and tempered after welding? The hardness after tempering should be 230–250 Brinell
Reply #22020-03-07
The quenching and tempering heat treatment processes for the two materials are different, mainly depending on the welding area of Q345B.

It is mainly 42crmo that is quenched and tempered; if welding is carried out after quenching and tempering, cracks are a concern

Why weld these two materials together? Is it for equipment, pipes, or a bolted structure? ? ?
