Eolas bunúsach
Feidhmchláir Choitianta
Tá raon leathan feidhmchlár ag barraí Babhta Cruach Dhosmálta 316 Grád, is féidir iad a ghearradh, a fhoirmiú agus a lúbadh, a shnáithiú, a dhruileáil agus a tháthú lena n-úsáid i:
Feidhmchláir Mhara
Timpeallachtaí Ceimiceacha
Axels & Seafta
Gríosaí & Grátaí
Scáileáin
Gríosaí Slándála
Innealtóireacht Ghinearálta
Ullmhúchán Dromchla agus Bratuithe
Murab ionann agus cruach éadrom ciallaíonn ceimic na steels dhosmálta go bhfuil na próisis agus na modhanna chun Cruach Dhosmálta 316 Grád a chosaint agus a chríochnú an-difriúil le cruach éadrom.Cuirfear an chuid is mó de na bailchríocha dromchla do chruach dhosmálta i bhfeidhm go meicniúil (Snasta) nó go ceimiceach (Pasivating).Beidh tionchar suntasach ag an bailchríoch dromchla ceart ar fheidhmíocht agus ar chuma do chruach dhosmálta.
Ceann de na cúinsí is tábhachtaí maidir le feidhmíocht agus cuma Steels Dhosmálta ná glaineacht.Ní mór dromchlaí a choinneáil saor ó cháithníní de mhiotail eile go háirithe cruach cóimhiotail nó carbóin.Tá ábhar salaithe ag adhmad freisin a dhéanfaidh cruach dhosmálta leech agus a stainse.
