Weldability :
without limitations
- welding is done without heating and subsequent heat treeting
limited weldability
- welding is possible under heating up to 100-120 grade and subsequent heat treeting
hard weldability
- obtaining the quality welding needs the additional operations:heating up to 200-300 grade; the heat treeting ia annealing
