DIN 17100 ST37-2 steel

Products from DIN 17100 ST 37-2 steels are use in welded, riveted and screwed structural components. DIN 17100 ST 37-2 steels are not intended for heat treatment - apart from stress-relieving heat treatment and normalizing.

DIN 17100 ST 37-2 steels suitability for welding:

1. Unlimited suitability of the DIN 17100 ST 37-2 steels for the various welding processes cannot be guaranteed, since the behaviour of a steel during and after welding depends not only on the DIN 17100 ST 37-2 material but also the conditions it experiences in manufacture and service.
2. Suitability for flash butt-welding and gas pressure welding generally exists with all the steels of this Standard including DIN 17100 ST 37-2, but it may be necessary in the case of steels with higher carbon content (ST50-2, ST60-2 & ST70-2) to carry out reheating after welding.
