Na'urar Walda ta Nickel da Nickel Alloy
Ni327-6
GB/T ENi6620
AWS A5.11 ENiCrMo-6
Bayani: Ni327 -6 lantarki ne mai tushen nickel tare da rufin sodium mai ƙarancin hydrogen. Yi amfani da DCEP (electrode na yanzu kai tsaye).tabbatacce). Karfe da aka ajiye yana da kyakkyawan ƙarfin lantarki, tauri da juriyar tsagewa. Karfe da aka ajiye yana da ma'aunin faɗaɗawa mai layi kamar na ƙarfe, kuma yana da ƙarfi mai yawa da juriyar tsatsa a zafin ɗaki da kuma zafin jiki mai yawa.
Amfani: Ana amfani da shi don walda ƙarfe na Ni9%, kuma ana iya amfani da shi don walda ƙarfe daban-daban da kuma ƙarfe masu wahalar walda.
