Sonraíocht Chaighdeánach ASTM A554 le haghaidh Feadáin Mheicniúil Cruach Dhosmálta Táthaithe
Is sonraíocht chaighdeánach é ASTM A554 a chumhdaíonn feadáin mheicniúla cruach dhosmálta austenític táthaithe agus feirritic atá beartaithe lena n-úsáid sna feidhmeanna ornáideacha, struchtúracha, sceite agus eile ina bhfuil gá le cuma, airíonna meicniúla nó friotaíocht creimeadh.
Clúdaíonn an tsonraíocht feadánra meicniúla mar-táthaithe nó fuar-laghdaithe i méideanna go 16 isteach. [406.4mm] toise lasmuigh, agus i dtiús balla 0.020 in. [0.51mm] agus os a chionn .
Cuirfear feadáin ar fáil i gceann de na cruthanna seo a leanas mar a shonróidh an ceannaitheoir: cruinn, cearnógach, dronuilleogach, nó cruth speisialta.
