430 kubbadaha birta ah ee birta ah waxay leeyihiin iska caabin daxalka ka hooseeya 302 ama 304 kubbadaha birta ah.Waxay iska caabiyaan biyaha saafiga ah, uumiga, hawada, saabuunta, saabuunta, asiidhyada organic iyo oxidated, xalalka alkaline.Uma diidaan chloride, fluoride, bromide, iodide xalalka.Ma adkaanayso haddii kulaylka la daweeyo.

• Waxaan ku hawlanayn wax soo saarka kubbadda birta in ka badan 26 sano;
Waxaan bixinaa noocyo kala duwan oo cabbirro ah oo u dhexeeya 3.175mm ilaa 38.1mm.Cabbirrada iyo cabbirrada aan caadiga ahayn waxaa lagu soo saari karaa codsi gaar ah (sida 5.1mm, 5.15mm, 5.2mm, 5.3mm 5.4mm for track the seat; 14.0mm for cam shaft and CV joint, iwm.);
● Waxa aanu haysanaa kayd balaadhan.Inta badan cabbirada caadiga ah (3.175mm ~ 38.1mm) iyo cabbirada (-8 ~ + 8) ayaa diyaar ah, kuwaas oo isla markiiba la keeni karo;
● Dufcad kasta oo kubadaha ah waxaa eegaya mashiino casri ah: tijaabiyaha wareega, tijaabiyaha qallafsanaanta, mikroskoob falanqaynta biraha, tijaabiyaha adkaanta (HRC iyo HV) si loo dammaanad qaado tayada.
S: Sideen ku dooran karaa sumadda birta ah ee ku habboon (304(L)/316(L)/420(C)/440(C))?Waa maxay faraqa ugu weyn ee u dhexeeya 300 iyo 400 ee kubbadaha birta ah ee taxanaha ah?
J: Si aad u dooratid nooca saxda ah ee birta ee kubbadaha birta ah, waa inaan si fiican u ogaanaa sifooyinka calaamad kasta iyo codsiga kubbadaha.Kubadaha birta ah ee ugu caansan ee la isticmaalo waxaa loo qaybin karaa si fudud laba kooxood: 300 taxane iyo 400 taxane ah.
300 taxane "austenitic" kubadaha aan birta lahayn waxay ka kooban yihiin chromium iyo nikkel dheeraad ah waxayna aragti ahaan yihiin kuwo aan magnet ahayn (dhab ahaantii aad bay u hooseeyaan.Sida caadiga ah waxaa la soo saaraa iyada oo aan habka daaweynta kulaylka.Waxay leeyihiin iska caabin daxalka ka wanaagsan 400 taxane ah (xaqiiqda, iska caabin daxalka ugu sareeya ee kooxda ahama. In kasta oo 300 kubadaha taxane ah oo dhan waa wax iska caabin ah, si kastaba ha ahaatee 316 iyo 304 kubadaha muujiyaan iska caabin kala duwan in ay walax qaar ka mid ah. Faahfaahin dheeraad ah, fadlan tixraac boggaga. ee kubbadaha birta ah ee kala duwan).Way jilicsan yihiin, sidaas awgeed waxaa sidoo kale lagu dabaqi karaa isticmaalka.400 ee kubbadaha birta ah ee taxanaha ah waxaa ku jira kaarboon badan, taas oo ka dhigaysa birlab iyo adkeysi badan.Si fudud ayaa loola dhaqmi karaa sida kubbadaha birta chrome ama kubbadaha birta kaarboon si loo kordhiyo adkaanta.Kubadaha birta ah ee 400 oo taxane ah ayaa caadi ahaan loo isticmaalaa codsiyada u baahan biyo-iska-caabbinta, xoogga, adkaanta iyo xidhashada caabbinta.
