| Baakad: | |
| Dabool caag ah si aad u ilaaliso labada daraf | |
| Shandad caag ah oo ku duudduuban tuubada dibadda | |
| Shandad tolsan oo ku duudduuban tuubo dibadda ah | |
| Dhammaan alaabadayada waa la raray, la kaydiyay, la raray si waafaqsan xeerarka caalamiga ah. | |
| Tuubooyinka waxaa lagu duuduubay warqad lid ku ah miridhku iyo siddo bir ah si looga hortago waxyeello.Calaamadaha aqoonsiga waxaa lagu calaamadeeyay si waafaqsan tilmaamaha caadiga ah ama tilmaamaha macmiilka.Baakad gaar ah ayaa loo heli karaa iyadoo loo eegayo shuruudaha macmiilka. | |
| Intaa waxaa dheer, sanduuqa alwaaxyada leh ayaa diyaar u ah ilaalin gaar ah.Noocyada kale ee baakadaha waa la bixin karaa haddii la codsado. | |
Macluumaadka aasaasiga ah
Dhexroor yar oo ah 321 tuubooyinka birta ah ee birta ah ayaa si aad ah uga wanaagsan iska caabinta daxalka intergranular kaas oo ah daxalka ka dhaca inta u dhaxaysa qaab-dhismeedka yar-yar -- inta u dhaxaysa miraha walxaha kala duwan ee ka samaysan alloy.321 SS, haddaba, waa ikhtiyaar shay muhiim ah oo loogu talagalay alaabada tuubada ee leh wareegyada adeegga ee 800-1500º roobabka carbide sababtoo ah nolosha badeecada waa la kordhin doonaa (marka loo eego darajooyinka kale ee birta ah).
Astaamaha & Codsiyada
321 tuubooyinka birta ah ee loo sameeyay codsiyada heerkulka sare waxay muujinayaan iska caabin heer sare ah oo daalka iyo dillaaca, taasoo ka dhigaysa mid ku habboon codsiyada ay ka mid yihiin:
Dooro codsiyada hawada sare
Qaybaha badan ee daashka
Codsiyada saliidda iyo gaaska/sifinta
Qalabka farsamaynta ee kiimikooyinka heerkulka sare leh
Codsiyo kale oo badan oo adeeg heerkul sare ah
Sida alaabtayada kale ee alxanka iyo la sawiro, dhexroor yar oo 321 tuubooyinka SS ah ayaa lagu alxanayaa kaydka xariijimaha, fur lagu sawiray qaabka gariiradda, la duuduubay sida loogu baahdo si loo buuxiyo shuruudaha xanaaqa macaamiisha, waxaana lagu bixiyaa dherer toosan ama foomka gariiradda.
