Qiimaha Jumlada ee Shiinaha Qiimaha Wanaagsan 30CrMo 42CrMo 15CrMo 16mn Kaarboon Bir ah oo aan Xirnayn Dhuumaha Birta Ss Pipe
Sharaxaad Gaaban:
42CrMo aluminium bir ah oo aan kala go 'lahayn waa bir aad u sareysa oo leh xoog sare iyo adayg, adkeysi wanaagsan, aan lahayn dabacsanaan cad, iyo qallafsanaan yar inta lagu jiro deminta.Deminta iyo xanaaqa ka dib, 42CrMo aluminium biibiile ah ayaa leh xad daal sare leh iyo iska caabin saameyn badan, saameyn wanaagsan oo adkeysi heerkul hoose ah, iyo xoog sare oo gurguurta iyo xoog adkeysi heerkul sare.Deminta dusha sare ee deminta iyo xanaaqa ka dib waxaa badanaa loo isticmaalaa nidaamka daawaynta kulaylka ee 42CrMo aluminium tubooyinka aan xidhnayn.
Waayo-aragnimada mashaariicda ee runtii aad u badan iyo hal ilaa hal nooc oo gaar ah ayaa ka dhigaya muhiimada la taaban karo ee isgaarsiinta ururka iyo fahamkeena sahlan ee filashadaada Qiimaha Jumlada Shiinaha Qiimaha Wanaagsan Dib u eeg si aad u hesho su'aalahaaga dhawaan.
Run ahaantii mashaariicda aad u fara badan ee khibradaha maamulka iyo hal ilaa hal nooc oo bixiye gaar ah ayaa ka dhigaya muhiimada la taaban karo ee xidhiidhka ururka iyo fahamkayaga fudud ee waxyaalaha aad ka filanaysoShiinaha Dhuumaha Birta Kaarboonka ah ee aan Xumaan lahayn iyo Dhuumaha Birta aan Xumaan lahayn, Waxaan si diiran u soo dhaweyneynaa mas'uuliyaddaada waxaana ugu adeegi doonaa macaamiisheena gudaha iyo dibaddaba alaab tayo sare leh iyo adeeg heer sare ah oo loogu talagalay isbeddelka horumarka dheeraadka ah sida had iyo jeer.Waxaan aaminsanahay inaad ka faa'iidaysan doonto xirfadeena dhawaan.
Ma laha dabacsanaan cad oo cadceed, qallafsanaan yar inta lagu jiro deminta, xadka daalka sare iyo iska caabbinta saamaynta badan ka dib deminta iyo daawaynta xanaaqa.42CrMo aluminium biibiile ah ayaa saameyn wanaagsan ku leh adkaanta heerkulka hooseeya iyo xoogga gurguurta ee sarreeya iyo xoogga dulqaadka heerkulka sare.Deminta dusha sare ee deminta iyo xanaaqa ka dib waxaa badanaa loo isticmaalaa nidaamka daawaynta kulaylka ee 42CrMo aluminium tubooyinka aan xidhnayn.

Codsiga 42CrMo aluminium bir ah oo aan kala go 'lahayn: birta gaarka ah ee loo isticmaalo buundooyinka waa "42CrMo", birta gaarka ah ee xirmooyinka baabuurta waa "42CrMo", birta gaarka ah ee maraakiibta cadaadiska waa "42CrMo".Birta noocaan ah waxay wanaajisaa sifooyinka birta iyadoo hagaajinaysa kaarboonka (c).Sidaa darteed, marka loo eego nuxurka kaarboonka, birta noocan oo kale ah waxaa loo qaybin karaa: birta kaarboon yar - nuxurka kaarboonku guud ahaan wuu ka yar yahay 0.25%, sida 10 iyo 20 birta;Birta kaarboon dhexdhexaadka ah - waxa ku jira kaarboon guud ahaan waa inta u dhaxaysa 0.25 iyo 0.60%, sida 35 iyo 45 birta;Birta kaarboonka sare - waxa ku jira kaarboon guud ahaan waa ka weyn yahay 0.60%.Noocan birta ah guud ahaan looma isticmaalo samaynta tubooyinka birta.
Codsiga caadiga ah
Ku habboon samaynta caagadaha waaweyn iyo kuwa dhexdhexaadka ah ee u baahan xoog iyo adag.
