1. Xulashada Walxaha Cayriin
Birta birta ah ama birta qashinka ah ee tayo sare leh ayaa la doortaa si loo hubiyo in halabuurka kiimikada uu buuxiyo shuruudaha ASTM A709.
2. Samaynta birta
Hababka Foornada Oxygen-ka ee Aasaasiga ah (BOF) ama Foornada Korontada (EAF) ayaa loo isticmaalaa in lagu dhalaaliyo walxaha ceeriin ah.
Walxaha isku-darka sida manganese, silicon, copper, nickel, iyo chromium ayaa lagu daraa si loo gaaro heerka iyo sifooyinka la rabo.
3. Jilidda
Birta dhalaalaysa waxaa lagu shubaa looxyo iyadoo la adeegsanayo habab shubid joogto ah ama qaabab shubid ah.
4. Duubista Kulul
Suunka waxaa lagu kululeeyaa heerkul sare (~1200°C) waxaana lagu duubaa saxaarado dhumucdoodu iyo ballaca loo baahan yahay leh.
Rogidda iyo qaboojinta la xakameeyey waxay xoojisaa sifooyinka farsamada sida xoogga wax soo saarka iyo adkeysiga.
5. Daaweynta Kulul (haddii loo baahdo)
Darajooyinka qaarkood (tusaale ahaan, HPS) waxaa laga yaabaa in la damiyo oo la kululeeyo si loo hagaajiyo xoogga, adkeysiga, iyo alxanka.
6.Daawaynta Dusha Sare
Saxannada waa la khafiifiyaa (qasacadaynta, gubashada rasaasta) si looga saaro lakabka oksaydhka loona diyaariyo habayn dheeraad ah ama dahaadh.
7.Jarista iyo Dhammaystirka
Saxannada waxaa loo gooyaa cabbirro cayiman, la kormeeraa, oo la tijaabiyaa sifooyinka farsamada, halabuurka kiimikada, iyo saxnaanta cabbirka sida waafaqsan heerarka ASTM A709.
8. Xakamaynta Tayada iyo Kormeerka
Saxan kasta wuxuu maraa tijaabo adag:
Tijaabooyinka xoogga jilicsanaanta iyo wax soo saarka
Imtixaanada saameynta Charpy
Baaritaanka Ultrasonic ama Ultrasound ee cilladaha gudaha
Kormeerka cabbirka iyo dusha sare
9. Baakadeynta iyo Bixinta
Taarikada la dhammeeyay waa la xirxiraa, la calaamadeeyaa, waxaana loo diyaariyaa in loo raro macaamiisha ama goobaha dhismaha.
Taarikada birta ah ee STM A709 badanaa waa taarikada birta ah ee qaab-dhismeedka oo xoog badan, oo aan daawad lahayn oo loogu talagalay in loo isticmaalo buundooyinka iyo codsiyada kale ee dhismaha ee culus. Isku-darka xooggooda, adkaysigooda, iyo alxanka ayaa ka dhigaya kuwo ku habboon mashaariicda kaabayaasha dhaqaalaha ee muhiimka ah.
