ASTM A213 T12(ASME SA213 T12) waa tuubo bir ah oo aan fiicneyn oo hooseeya oo loogu talagalay adeegga heerkulka sare.
Qaybaheeda asaasiga ah waa 0.80-1.25% chromium iyo 0.44-0.65% molybdenum, taas oo u kala saarta sida birta chromium-molybdenum. Waxaa si weyn loogu isticmaalaa jawi kuleyl sare iyo cadaadis sare sida kuleyliyaha, kulayliyaha sare, iyo kulaylka beddelayaasha.
Tuubbada T12 waxay leedahay ugu yaraan awoodda xajinta ee 415 MPa iyo awoodda wax-soo-saarka ugu yar ee 220 MPa.
UNS u qoondaynta darajadan waa K11562.
Botop Steel waa xirfadle lagu kalsoon yahay oo lagu kalsoonaan karo kaydiyaha tuubooyinka birta birta ah iyo jumlayda gudaha Shiinaha, awood u leh inay si dhakhso leh u keento mashaariicdaada darajooyin kala duwan oo tuubooyinka birta alloy ah, oo ay ku jiraanT5 (K41545), T9 (K90941), T11 (K11597), T12 (K11562), T22 (K21590)iyoT91 (K90901).
Badeecadahayadu waa tayo la isku halayn karo, si tartan ah loo qiimeeyay, waxayna taageertaa kormeerka qolo saddexaad.

Soo saaraha iyo Xaaladda
ASTM A213 T12 tuubooyinka birta waa in lagu sameeyaa habka aan kala go 'lahayn oo waa inay noqdaan kuwo kuleyl ah ama la dhammeeyey qabow, sida lagu cayimay.
Daawaynta kulaylka
Dhammaan tuubooyinka birta ee T12 waa inay maraan daawaynta kulaylka.
Hababka daaweynta kulaylka la oggol yahay waxaa ka mid ah full ama isothermal annealing, caadiyeyn iyo xanaaqid, amasubcritical annealing.

| subcritical anneal | 1200-1350 ℉ [650-730 ℃] |
Waa in la ogaadaa in daaweynta kulaylka ay tahay in si gaar ah loo fuliyo iyo marka lagu daro samaynta kulul.

Waa la ogol yahay in la dalbado T12 oo leh ugu badnaan sulfur 0.045. Calaamadaynta waa in lagu daraa xarafka "S" ee raacaya calaamadaynta darajada, sida ku jirta T12S.

| Tijaabada fidsan | Hal tijaabo oo fidsan waa in lagu sameeyaa muunado laga soo bilaabo daraf kasta oo tuubo dhammaatay, oo aan ahayn kan loo isticmaalo baaritaanka ololka, qayb kasta. | |
| Tijaabada Dhalinta | Hal tijaabo oo ifaysa waa in lagu sameeyaa shaybaar laga soo bilaabo daraf kasta oo tuubo dhammaatay, ma aha kan loo isticmaalo baadhista fiditaanka, qayb kasta. | |
Tuubo kasta waa in la mariyaa tijaabada koronto ee aan burbursanayn ama tijaabada hydrostatic.Nooca tijaabada ah ee la isticmaalayo waa in ay ahaataa ikhtiyaarka soo saaraha, haddii aan si kale loo sheegin amarka iibka.
Hababka tijaabada waa in loo fuliyaa si waafaqsan shuruudaha lagu dabaqi karo ee qaybaha 25 iyo 26 ee ASTM A1016.
ASTM A213 T12 cabbirka tubbada iyo dhumucda gidaarada waxaa badanaa lagu gogladaa dhexroor u dhexeeya 3.2 mm ilaa dhexroorka ka baxsan 127 mm, iyo dhumucda ugu yar ee 0.4 mm ilaa 12.7 mm.
Cabbirrada kale ee tuubooyinka birta ee T12 ayaa sidoo kale la keeni karaa, waase la buuxiyey dhammaan shuruudaha kale ee ASTM A213.
ASTM A213 T12 aluminium bir bir ah oo aan lahayn tuubooyinka ugu horrayn waxaa lagu isticmaalaa jawi kuleyl sare iyo cadaadis sarreeya. Codsiyada caadiga ah waxaa ka mid ah
1. Kuleyliyaha sare iyo kuleyliyaha
Loo isticmaalo dhirta korontadu kuleyliyaha sare iyo tuubooyinka dib u kululeeyaha ee ku shaqeeya heerkul sare iyo cadaadis.
Si ballaaran loogu dabaqay sida tuubooyinka kuleyliyaha ee xarumaha tamarta kulaylka, unugyada ka soo kabashada kulaylka, iyo kuleyliyeyaasha warshadaha.
3. Kuleylleyda
Ku habboon tuubooyinka kulaylka beddelka ee warshadaha petrochemical iyo kiimikooyinka sababtoo ah caabbinta gurguurta ee wanaagsan iyo xasilloonida kulaylka.
4. Foornada iyo Tubooyinka kuleylka
Lagu rakibay gariiradaha foornada sifaynta, tuubooyinka kuleyliyaha, iyo kuleyliyeyaasha habka halkaas oo caabbinta oksaydhka iyo xoogga muddada dheer looga baahan yahay.
5. Cadaadiska Tuubooyinka Korontada iyo Dhirta Kiimikada
Loo isticmaalo dhuumaha heerkulka sare leh, oo ay ku jiraan xadhkaha uumiga iyo khadadka gaadiidka dareeraha kulul.
