Sreang Earraigh Cruach Tempered Ola

Le taithí agus saineolas leathan, tá Friend Metal ag gabháil do fhorbairt, do mhonarú agus do mhargaíocht sreang earrach cruach ola tempered ASTM-A230-99, ASTM-A401, EN10270-2, JIS G3561. Mar mhonaróir gairmiúil, tugann muid anois sreanga cruach éagsúla ardchaighdeáin a dhéantar sa tSín duit a thagann i neart ard, toughness maith agus friotaíocht caitheamh den scoth. Cuirimid fáilte roimh d'orduithe saincheaptha freisin.

 

1) Réamhrá:

 

Is sreang cruach í sreang tempered Ola le leaisteachas agus insínteacht níos fearr a fhaightear trí phróiseas ola-mhúchadh agus tempered. Tá friotaíocht den scoth ag sreang OT i gcoinne teasa, tuirse agus dífhoirmithe. Is iad príomh-iarratais sreang OT spriongaí le haghaidh ualaí dinimiciúil arís agus arís eile, lena n-áirítear earrach comhla inneall.
