Apejuwe: Ni307-1 jẹ elekiturodu ti o da lori nickel pẹlu ideri iṣuu soda hydrogen kekere.Lo DCEP (daadaa elekiturodu lọwọlọwọ taara).Niwọn igba ti weld naa ni Nb, irin ti a fi silẹ ni ṣiṣu ti o dara ati idena kiraki.
Ohun elo: Lo fun alurinmorin ti nickel-chromium-iron alloys (gẹgẹ bi awọn UNS N06600, UNS N06601) ati surfacing ti irin.Ni o dara dissimilar irin alurinmorin-ini.O tun le ṣee lo ni iwọn otutu ti o ṣiṣẹ ti 980 ° C, ṣugbọn nigbati iwọn otutu ba ga ju 820 ° C, resistance ifoyina ati agbara yoo dinku.
