Hastelloy C-276® jẹ nickel-molybdenum-chromium alloy pẹlu ipata ipata to dara julọ ni awọn agbegbe ti o lagbara.Nickel ti o ga ati awọn akoonu molybdenum jẹ ki irin nickel, irin ni pataki sooro si pitting ati ipata crevice ni idinku awọn agbegbe lakoko ti chromium ṣe afihan resistance si media oxidizing.Botilẹjẹpe awọn iyatọ pupọ wa ti alloy nickel Hastelloy, Hastelloy C-276 jẹ eyiti o lo pupọ julọ.
Akopọ ti awọn abuda Hastelloy C-276:
Hastelloy C-276 (N10276) ni o ni ipata ipata to dara julọ si ọpọlọpọ awọn media ti o bajẹ labẹ ifoyina ati awọn ipo idinku.O tayọ resistance si pitting ipata, crevice ipata ati wahala ipata wo inu.Alloy jẹ o dara fun ọpọlọpọ awọn ile-iṣẹ ilana kemikali ti o ni oxidizing ati idinku awọn media.Akoonu ti o ga julọ ti molybdenum ati chromium jẹ ki alloy sooro si ipata nipasẹ awọn ions kiloraidi, ati pe tungsten tungsten tun ṣe ilọsiwaju resistance ipata rẹ.
Hastelloy C-276 jẹ ọkan ninu awọn ohun elo nikan ti o le koju ipata ti chlorine tutu, hypochlorite ati ojutu chlorine oloro.Alloy ni o ni pataki ipata resistancetohigh-fojusi chlorinated iyọ ojutu (gẹgẹ bi awọn chlorinated Iron ati Ejò kiloraidi).
