Suidheachadh lìbhrigidh
Ainmeachadh | samhladh | Tuairisgeul |
Crìochnaichte fuar (cruaidh) | BK(+C) | Cha bhith pìoban a’ faighinn làimhseachadh teas às deidh an fuachd mu dheireadh a chruthachadh agus, mar sin, tha iad gu math àrd an aghaidh deformachadh |
Crìochnaichte fuar (bog) | BKW | Tha an làimhseachadh teas mu dheireadh air a leantainn le dealbh fuar le beagan deformachadh.Tha tuilleadh giollachd iomchaidh a’ ceadachadh ìre sònraichte de fhuarachadh (me lùbadh, leudachadh) |

Crìochnaichte fuar agus faochadh cuideam | BKS(+SR) | Tha làimhseachadh teas air a chuir an sàs às deidh a ’phròiseas cruthachadh fuachd mu dheireadh.Le ùmhlachd do chumhachan giullachd iomchaidh, tha an àrdachadh anns na cuideaman a tha air fhàgail a ’comasachadh an dà chuid cruthachadh agus innealachadh gu ìre. |
Annealed | GBK(+A) | Tha am pròiseas cruthachaidh fuachd mu dheireadh air a leantainn le bhith a’ annealing ann an àile fo smachd. |
Normalaichte | NBK(+N) | Tha am pròiseas cruthachaidh fuar mu dheireadh air a leantainn le bhith a’ cur anail os cionn na h-ìre cruth-atharrachaidh àrd ann an àile fo smachd. |
