20g birta birta ah ee tubada GB5310 cadaadiska sare ee tuubada kululeeyaha
Sharaxaad Gaaban:
20G tuubo bir ah oo aan kala go 'lahayn waa bir qaabdhismeed tayo sare leh, walxo kuleyliyaha, kaarboonka 0.17-0.24%, xoogga xajinta ee 410Mpa, dhibicda 230-250Mpa.Miyuu yahay wax-soo-saarkayaga ugu weyn ee birta, waxaan ku siin karnaa 20G tuubo aan cillad lahayn oo leh tayo sare iyo qiimo tartan leh.Halkan si aan kuugu baro 20G tuubooyin aan sina lahayn sifooyinka kiimikada aasaasiga ah iyo sifooyinka farsamada.
Waxaan sidoo kale xoogga saarnay hagaajinta maamulka waxyaabaha iyo habka QC si aan u sii wadno inaan sii wadno faa'iidada weyn ee gudaha shirkadda tartan adag20g Dhuumaha Birta aan Xumaan lahaynGB5310 tuubbada kululeeyaha cadaadiska sare, Shirkadeena waxay ilaalisaa badbaadada iyo abaabulka badbaadada leh oo ay weheliso runta iyo daacadnimada si ay uga caawiso inay sii wadato xidhiidhka muddada-dheer iibsadayaashayada.
