Saxanka birta kaarboon waa mid ka mid ah qaybaha aasaasiga ah ee qalabka birta. Waxay ku salaysan tahay birta, oo leh kaarboonka inta u dhaxaysa 0.0218% -2.11% (heerka warshadaha), oo ay ku jiraan wax yar ama qadar yar oo ah walxo daawaynta. Marka loo eego nuxurka kaarboonka, waxa loo qaybin karaa:
Bir kaarboon yar(C≤0.25%): adag tahay, fududahay in la farsameeyo, Q235 waxay ka tirsan tahay qaybtan;
Bir kaarboon dhexdhexaad ah(0.25%
Bir kaarboon sare leh(C>0.6%): engegnaan aad u sarreeya iyo jajabnaan sare.
Q235 birta kaarboon: qeexida iyo cabirrada xudunta u ah (GB/T 700-2006 heerka)

Guryaha makaanikada:
Xoogga wax-soosaarka: ≥235MPa ( dhumucdiisuna ≤16mm)
Xoog xajin: 375-500MPa
Kordhinta: ≥26% ( dhumucdiisuna ≤16mm)
Qalabka iyo Waxqabadka
Qalab:Qalabka caadiga ah waxaa ka mid ahGR.B, X42, X46, X52, X56, X60, X65, X70iwm.
Tilmaamaha Waxqabadka
Xoog SareAwood u leh inuu u adkeysto cadaadiska sare ee ka yimaada dareeraha sida saliidda iyo gaasta dabiiciga ah inta lagu jiro gaadiidka.
Adayg sare: Ma fududa in la jebiyo marka ay la kulmaan saameyn dibadeed ama isbeddel juquraafi ah, iyada oo la hubinayo hawlgalka badbaadada ee dhuumaha.
Iska caabinta Daxalka Wacan: Marka loo eego jawiga isticmaalka kala duwan iyo warbaahinta, doorashada qalabka ku habboon iyo hababka daaweynta dusha sare waxay si wax ku ool ah uga hortagi karaan daxalka waxayna kordhiyaan nolosha adeegga dhuumaha.
Astaamaha "dagaalyahanka laba geesoodka ah" ee Q235
Waxqabadka Habraaca Wacan
Weldability: Looma baahna kuleyl ka hor, ku habboon alxanka arc, alxanka gaaska iyo hababka kale (sida dhismaha alxanka qaab dhismeedka birta);
Samaynta QabowSi fudud ayaa loo foorarsan karaa loona shaabadeeyey (tusaale: qolof sanduuqa qaybinta, tuubada hawo-mareenka);
MashiinkaWaxqabadka xasiloon ee hoos u dhaca goynta-xawaaraha hooseeya (waxqabadka qaybaha mishiinka).
Isu-dheelitirnaanta Farsamada oo Dhamaystiran
Xoog vs Adag: 235MPa awoodda wax-soo-saarka waxay ku xisaabtantaa labadaba culeyska-qaadista iyo iska caabbinta saameynta (marka la barbardhigo Q195's 195MPa);
Laqabsiga Daawaynta Dusha sare: Si fudud loo galvanize iyo buufin rinjiga (sida darbiyada, keelyada birta fudud).
Waxtarka Dhaqaale ee Sare
Kharashku wuxuu ku saabsan yahay 15% -20% ka hooseeya kan birta birta ah ee xoogga leh ee hooseeya (sida Q345), oo ku habboon codsi ballaaran.
Heerarka Heerka Sare
Dhumucda guud: 3-50mm (saami ku filan, yaraynta wareegga habeynta);
Heerarka fulinta: GB/T 700 (gudaha), ASTM A36 (caalami ah oo u dhigma).
Iibso oo isticmaal "Hagaha Ka-hortagga"
Aqoonsiga Tayada:
Muuqashadadildilaac la'aan, nabarro, laalaabka (GB/T 709 saxan qaabka caadiga ah);
Dammaanad: Hubi halabuurka, qalabka farsamada iyo warbixinta ogaanshaha cilladaha ( ogaanshaha cilladaha UT ayaa looga baahan yahay qaybaha dhismaha ee muhiimka ah).
Istaraatiijiyada ka hortagga daxalka:
Gudaha: rinjiga ka hortagga miridhku (sida rinjiga rasaasta cas) + koodhka sare;
Banaankagalvanizing kulul-muquufin (dahaarka ≥85μm) ama buufin daahan fluorocarbon.
Xusuusin alxanka:
Xulashada usha alxanka: E43 taxane (sida J422);
Saxan khafiif ah(≤6mm): kuleyl hore looma baahna, saxan dhumuc weyn leh (> 20mm): horay u sii 100-150℃ si aad uga hortagto dildilaaca.
Na raac si aad wax badan uga barato khibradda birta.
