Is cóimhiotal saoirsithe nicil-cróimiam-moluibdín é HASTELLOY a mheastar a bheith ar an gcóimhiotal is solúbtha atá frithsheasmhach in aghaidh creimeadh atá ar fáil.
Tá an cóimhiotal seo frithsheasmhach in aghaidh foirmiú deascán teorann gráin sa chrios atá buailte ag teas an táthú, rud a fhágann go bhfuil sé oiriúnach don chuid is mó d'fheidhmchláir phróisis cheimiceacha i riocht táthaithe. Foirm Hastelloy: Píopa / Feadán (táthaithe agus gan uaim), Pláta / Bileog, Barra, Sreang, Feistis
Sreang: 0.01-10mm
Stiall: 0.05 * 5.0-5.0 * 250mm
Barra: φ4-50mm; Fad 2000-5000mm
Píopa: φ6-273mm;δ1-30mm;Fad 1000-8000mm
Bileog: δ 0.8-36mm; Leithead 650-2000mm; Fad 800-4500mm
