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 |
