Is cóimhiotal saoirsithe nicil-chromium-chromium-mhóilíneach é Hastelloy a mheastar a bheith mar an cóimhiotal is ildánach atá ar fáil i gcoinne creimthe atá ar fáil.
Tá an cóimhiotal seo frithsheasmhach in aghaidh foirmiú na teorann gráin i gcrios a bhfuil tionchar aige ar theas táthaithe, rud a fhágann go bhfuil sé oiriúnach don chuid is mó d'iarratais ar phróisis cheimiceacha i riocht mar táthaithe.
