Ni70Cr30 jẹ austenitic nickel-chromium alloy ti o dara fun awọn ohun elo iwọn otutu to 1250°C. Akoonu chromium giga (30% ni apapọ) pese akoko igbesi aye ti o dara pupọ, paapaa ni awọn ohun elo ileru. Ni70Cr30 jẹ ijuwe nipasẹ resistivity giga, resistance ifoyina ti o dara, ductility ti o dara lẹhin lilo ati weldability to dara julọ.
Ni70Cr30 ni a lo fun awọn eroja alapapo ina ni awọn ileru ile-iṣẹ. Awọn ohun elo aṣoju jẹ: ina ati awọn ileru enamelling, awọn igbona ibi ipamọ, awọn ileru ati awọn kilns pẹlu awọn agbegbe iyipada.
