Ábhar táirge
Is éagsúlachtaí iad cóimhiotail 304 (S30400) agus 304L (S30403) den chóimhiotal austenític nicile 18 faoin gcéad - 8 faoin gcéad, an cóimhiotal is eolach agus is minice a úsáidtear sa teaghlach cruach dhosmálta.
Is gnáthchleachtas é 304L a dheimhniú go dé mar 304 agus 304L. Cuireann an cheimic ísealcharbóin de 304L in éineacht le breisiú nítrigine ar chumas 304L airíonna meicniúla 304 a chomhlíonadh.
Cosnaíonn Alloy 304/304L creimeadh an atmaisféir, chomh maith le timpeallachtaí measartha ocsaídeacha agus laghdaithe. Tá friotaíocht den scoth ag an gcóimhiotal le creimeadh intergranular sa riocht mar-táthaithe. Tá neart agus toughness den scoth ag Alloy 304/304L ag teochtaí crióigineacha.
Tá Alloy 304/304L neamh-mhaighnéadach sa riocht annealed ach féadann sé éirí beagán maighnéadach mar thoradh ar fhuar-obair nó táthú. Is féidir é a tháthú agus a phróiseáil go héasca ag cleachtais déantúsaíochta caighdeánach siopa.
