Léiríonn Feadáin Gan uaim Cruach Carbóin Grád BS 1387, a aithnítear go coitianta mar phíobáin agus feadáin cruach éadrom, catagóir d’fheadáin cruach carbóin atá éifeachtach ó thaobh costais de. Tá na feadáin seo tréithrithe ag cion carbóin suas le 0.20% agus ábhar mangainéise suas le 1.20%, rud a fhágann go bhfuil foirmiúlacht agus intuargaineacht den scoth acu. Monaraithe i gcomhréir dhlúth le sonraíocht BS (Caighdeán na Breataine), tá siad ar eolas go forleathan i gciorcail tráchtála mar phíobáin CS (cruach carbóin) nó píopaí MS (cruach éadrom).
Go háirithe, léiríonn píopaí cruach carbóin íseal cruas níos lú i gcomparáid le píopaí cruach carbóin ard. Mar sin féin, is féidir a gcruasacht dromchla a fheabhsú trí phróiseas ar a dtugtar carburizing, a scaipeann carbóin isteach i gciseal seachtrach an ábhair. Tá Feadáin Grád BS 1387 oiriúnach d'fheidhmchláir éagsúla a dteastaíonn comhpháirteanna cruach foirmithe de bharr an teaglaim seo d'inacmhainneacht, d'inoibritheacht agus d'acmhainneacht cruaite dromchla.
Feadáin agus Feadáin Cruach BS 1387/85 Oiriúnach le haghaidh Scriú go Snáitheanna Píobáin BS 21
