Kanaalka birta ah ee birta ah ee dhammaan dhinacyada nuxurka: Qaybaha jilicsanaanta birta ah sida loo doorto saliidda jilicsan ee birta si loo yareeyo kharashka dhamaystiran?Hadda, qiimaha halbeegga ee qaybaha xajinta birta aan qaali ahayn, laga yaabee mid aad u jaban in lagu qeexo, maaha mid aad u badan.In jawi tartan qiimo jaban homogenized suuqa kala iibsiga, qaybo badan oo ahama ahama qaybo ka mid ah, iibsashada ee saliid jilicsan birta ahama waa ka jaban yahay, darajada waa ka sii xun si ay u iibsadaan.Ujeedadu waa in la dhimo kharashaadka si kasta oo suurtagal ah.Sannadkan, waxaan helay dhacdo "la yaab leh", iibso macaamiisha saliidda ee birta aan wanaagsanayn, aad iyo aad u badan.Saliidda birta fidsan ee birta-kala-baxa, macaamiil aad iyo aad u tiro badan si ay u iibsadaan GAviao D-100E saliid fidsan birta-la'aanta ah.Maanta iyo qaybo jilicsan oo birta ah oo farsameeya Chen chat heerka sare ah, ayuu yidhi, hadda qaali macmal ah, kharashyada farsamaynta qaybaha birta birta ah ayaa sarreeya oo sarreeya.Haddii saliida fidsan birta aan si khaldan loo xushay, waxaa jira qashin badan, burs iyo dib u shaqayn, taasoo keentay qashin dhaaftay saliida fidsan birta aan la kala bixin lafteeda.Shirkaddu waxay ku takhasustay wax soo saarka birta austenitic TP304, 304L, 321,316,316,3101S iyo 31803,904L birta duplex iyo birta austenitic super austenitic, alaabooyinka waxaa si weyn loogu isticmaalaa duulista, batroolka, tamarta nukliyeerka, daawada, dhoofinta iyo warshadaha kale. loo dhoofiyo Maraykanka, Russia, India, South Korea, Japan, iyo sidoo kale dalalka Yurub iyo Koonfur-bari Asia, si buuxda u buuxin kara shuruudaha macaamiisha meelo kala duwan.Awoodda wax-soo-saarka ee 2205 birta-duplex-ka-duplex waxay laba jeer ka badan tahay birta austenitic.Habkani wuxuu u oggolaanayaa naqshadeeyayaasha inay yareeyaan miisaanka marka ay naqshadeynayaan alaabooyinka, taasoo ka dhigaysa daawayntan mid ka jaban 316,317 L. Qalabkani wuxuu si gaar ah ugu habboon yahay isticmaalka heerkulka -50 ° F / + 600 ° F.Codsiyada ka baxsan xadkan heerkulka ayaa sidoo kale laga yaabaa inay tixgeliyaan daawayntan, laakiin waxaa jira mid.
