Codsiga Alaabta

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 weelasha cadaadiska waa "42CrMo".Birta noocaan ah waxay wanaajisaa sifooyinka birta iyadoo hagaajinaysa kaarboonka (c).Sidaa darteed, marka loo eego nuxurka kaarboonka, birta noocaan ah waxaa loo qaybin karaa: birta kaarboon yar -- waxa ku jira kaarboonku guud ahaan waa ka yar yahay 0.25%, sida 10 iyo 20 birta;Birta kaarboon dhexdhexaadka ah -- waxa ku jira kaarboonku 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.
