China Molemo Oxidation Resistance NiCr 70/30 bakeng sa Heating Cables Ho Etsa le Feme

Good Oxidation Resistance NiCr 70/30 bakeng sa Lithapo Tse Futhumatsang Setšoantšo se Hlahelitsoeng

Ho hanyetsa oxidation e ntle ea NiCr 70/30 bakeng sa lithapo tse futhumatsang

Tlhaloso e Khutšoanyane:

NiCr 70/30 (2.4658) ke austenitic nickel-chromium alloy (NiCr alloy) bakeng sa ho sebelisoa mocheso o fihlang ho 1250°C. Motsoako oa 70/30 o khetholloa ka ho hanyetsa ho phahameng le ho hanyetsa oxidation e ntle. E na le ductility e ntle ka mor'a tšebeliso le weldability e ntle haholo.
