Is cóimhiotal nicil-resistant creimeadh-bhunaithe é Hastelloy, atá roinnte go príomha i dhá chatagóir: cóimhiotal nicil-cróimiam agus cóimhiotal nicil-cróimiam-moluibdín. Tá friotaíocht maith creimeadh agus cobhsaíocht theirmeach ag Hastelloy, agus úsáidtear é den chuid is mó in eitlíocht, réimsí ceimiceacha, etc.
ERNiCrMo-4a úsáidtear le haghaidh táthú gás-tungstain-stua agus gás-miotail-stua cóimhiotal Inconel C-276 agus cóimhiotail nicil-cróimiam-moluibdín eile. Mar gheall ar ard-ábhar moluibdín, cuireann an cóimhiotal seo friotaíocht den scoth ar fáil do scoilteadh strus-chreimeadh agus do chreimeadh creimthe agus crevice.
