Is éagsúlachtaí iad cóimhiotail 304 (S30400) agus 304L (S30403) ar an cruach dhosmálta austenític nicile 18% a aithnítear go forleathan agus a úsáidtear go coitianta.
De ghnáth, déantar dé-dheimhniú ar 304L mar 304 agus 304L araon. Ligeann a ábhar ísealcharbóin, chomh maith le nítrigin bhreise, do 304L na hairíonna meicniúla céanna a bhaint amach le 304.
Cuireann an dá chóimhiotail friotaíocht ar chreimeadh an atmaisféir agus feidhmíonn siad go maith i dtimpeallachtaí measartha ocsaídeacha agus laghdaithe. Ina bhfoirm táthaithe, léiríonn siad friotaíocht láidir le creimeadh intergranular. Coinníonn siad neart agus toughness den scoth, fiú ag teocht chrióigineacha.
Sa stát annealed, tá 304/304L neamh-mhaighnéadach ach féadfaidh sé maighnéadas beag a thaispeáint tar éis fuar-obair nó táthú. Is féidir na cóimhiotail seo a tháthú agus a phróiseáil go héasca trí úsáid a bhaint as modhanna caighdeánacha monaraithe3
