Technological properties of the material 20KH2G2SR ( 20H2G2SR, 20Õ2Ã2ÑÐ ) .
Weldability:
without limitations.
Specification :
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
