These fine-grain structural steel grades are not suitable for heat treatment above 580 centidegree. Stress relief annealing is required only if called for in the regulations or if manufacturing conditions make a reduction of the residual welding stresses appear useful. The holding time should be between 30 and 60 minutes.
