Hastelloy C-4 (UNS NO6455)
Awọn ẹya Hastelloy C-4 ati Akopọ Awọn ohun elo:
Awọn alloy jẹ austenitic kekere-erogba nickel-molybdenum-chromium alloy. Iyatọ akọkọ laarin Nicrofer 6616 hMo ati awọn ohun elo miiran ti iṣelọpọ kemikali ti o jọra ni iṣaaju jẹ erogba kekere, silikoni, irin ati tungsten. Ipilẹ kemikali yii n pese iduroṣinṣin to dara julọ ni 650-1040 ° C ati ilọsiwaju ti o ni ilọsiwaju si ipata intergranular, yago fun ailagbara ila ila eti ati ibaje HAZ weld labẹ awọn ipo iṣelọpọ ti o yẹ. Alloy lo ninu flue gaasi desulfurization awọn ọna šiše, pickling ati acid olooru ọgbin, acetic acid ati ogbin kemikali gbóògì, titanium oloro gbóògì (chloride ọna), electrolytic plating.
