bidh boltaichean crann air an dèanamh tro phròiseas cinn fuar a’ cleachdadh stuth amh de stàilinn 40Cr.Thathas a’ gabhail ri dòigh làimhseachaidh teas gus cruas na bolt àrdachadh gu ìre 12.9, a’ leigeil leis na boltaichean crann a bhith freagarrach airson tagraidhean a dh’ fheumas coileanadh àrd caitheamh caitheamh.Tha na boltaichean crann againn gu ìre mhòr freagarrach airson na lannan a cheangal ri luchd-brathaidh de bhrandan leithid CAT, Komatsu, msaa.
