Tlhaloso: R107 ke pearlitic e sa keneleng mocheso eleketrode ea tšepe e nang le sodium e tlase ea hydrogen coating e nang le 0.5% Mo. Sebelisa DCEP (electrode ea hona joale e nepahetseng) 'me e ka chesetsoa maemong ohle. The weldment e tlameha ho futhumatsoa ho 90 ~ 110 ℃ pele ho tjheseletsa. .
Kopo: E sebelisetsoa ho tjheseletsa liphaephe tsa boiler tse nang le mocheso o sebetsang o ka tlase ho 510 ° C (joalo ka 15Mo, joalo-joalo), 'me e ka boela ea sebelisoa bakeng sa ho tjheseletsa tšepe e tloaelehileng e tlaase ea alloy high-power.
