Warshada Dhuumaha ee Shandong si ay u soo bandhigto 16Mn dhexroor yar oo bir bir ah oo aan fiicneyn
16Mn dhexroor yar oo bir ah oo aan lahayn bir ah waa walxo bir ah oo aad loo isticmaalo.
GB/T8163-2008 (gudbinta dareeraha) GB6479-2000 (tuubo bir ah oo aan fiicnayn oo loogu talagalay qalabka bacriminta cadaadiska sare)
Noocan birta ah waa in la hagaajiyo sifooyinka farsamada ee birta iyadoo la hagaajinayo qadarka kaarboon (C).Sidaa darteed, marka loo eego heerka kaarboonka, birta noocan oo kale ah ayaa loo sii kala qaybin karaa: birta-kaarboon-yar-yar-karboonka guud ahaan waa wax ka yar 0.25%, sida 10, 20 birta, iwm.;Birta kaarboon dhexdhexaadka ah - Waxyaabaha kaarboonku guud ahaan waa inta u dhaxaysa 0.25 ~ 0.60%, sida 35,45 birta, iwm.;Birta kaarboonka sare - Waxyaabaha kaarboonku guud ahaan waa ka weyn yahay 0.60%.Noocan birta ah guud ahaan looma isticmaalo samaynta tubooyinka birta.
16Mn habka tuubada aan kala go'a lahayn: tuubada bannaan - kormeerka - diirinta - kormeerka - kululaynta - daloolista - qajaarka - shiidi - qalajinta saliidda - alxanka madaxa - sawir qabow - daaweynta xalka - - pickling - pickling passivation - kormeerka - duubista qabow - saliid - madax goynta - hawo qalajinta - dhalaalid gudaha - dhalaalid dibadda - kormeerka - calaamadaynta - baakad dhammaatay
1. Hababka wax-soo-saarka: Marka loo eego hababka wax-soo-saarka ee kala duwan, tuubooyinka kulul ee duuban, tuubooyinka qabow-duubka, tuubooyinka qaboojiyaha, tuubooyinka dibadda, iwm ayaa la kala saari karaa.
