Weldability:
without restrictions
limited weldability
difficult to weld
- welding is performed without heating and without subsequent heat treatment
- welding is possible with heating up to 100–120 degrees and subsequent heat treatment
- to obtain high-quality welded joints, additional operations are required: heating up to 200–300 degrees during welding, heat treatment after welding – annealing
