Clúdaíonn sonraíocht ASTM A789/A789M ceanglais chaighdeánacha maidir le gráid de thiús balla ainmniúil, agus feadánra cruach dhosmálta le haghaidh seirbhísí a éilíonn friotaíocht ginearálta creimeadh, le béim ar leith ar fhriotaíocht in aghaidh scoilteadh creimeadh struis. Tá na steels seo so-ghabhálach i mbrabú má úsáidtear iad ar feadh tréimhsí fada ag teochtaí ardaithe.
Déanfar anailísí teasa agus táirge ina gcloífidh an cruach leis an gcomhdhéanamh ceimiceach is gá le haghaidh carbóin, mangainéise, fosfar, sulfair, sileacain, nicil, cróimiam, moluibdín, nítrigine, copar, agus eile.
Cuirfear gach feadáin ar fáil sa riocht teaschóireáilte de réir na gcoinníollacha sonraithe teochta agus múchadh. Nuair a bhíonn an chóireáil teasa deiridh i bhfoirnéis leanúnach, nó nuair a fhaightear riocht cóireála teasa teasa go díreach trí múchadh tar éis foirmiú te, déanfar líon na feadáin den mhéid céanna agus ón teas céanna i go leor a chinneadh ó mhéideanna forordaithe na feadáin.
Cloífidh an t-ábhar leis na hairíonna teanntachta agus cruais atá leagtha síos. Déanfar tástálacha meicniúla ar an bhfeadán cruach, mar shampla tástáil teannais, tástáil bladhmadh (feadáin gan uaim), tástáil feadáin (feadáin táthaithe), tástáil chruas agus tástáil leascaithe droim ar ais. Cuirfear gach feadán faoi réir na tástála leictreacha neamh-millteach nó na tástála hidreastatach freisin.
