Ni70Cr30 ndi austenitic faifi tambala-chromium aloyi oyenera ntchito kutentha ntchito mpaka 1250 °C. Zomwe zili mu chromium (30% pafupifupi) zimapereka nthawi yabwino kwambiri yamoyo, makamaka muzogwiritsa ntchito mung'anjo. Ni70Cr30 imadziwika ndi resistivity mkulu, wabwino makutidwe ndi okosijeni kukana, ductility wabwino pambuyo ntchito ndi weldability kwambiri.
Ni70Cr30 imagwiritsidwa ntchito popangira zinthu zamagetsi zamagetsi m'ng'anjo zamakampani. Zomwe zimagwiritsidwa ntchito ndizo: ng'anjo zamagetsi zamagetsi ndi enamelling, zotenthetsera zosungirako, ng'anjo ndi ng'anjo zokhala ndi mpweya wosinthika.
Makina Okhazikika (1.0mm)
- kukula: 30%
- Kuchuluka Kwambiri: 420Mpa
- Kuthamanga Kwambiri: 810Mpa
