ASTM A36 bir ah

AsTM A36 Taargada Qaab-dhismeedka Kaarboon

AsTM A36 saxan bir ah waa badeecada birta-lulaynta ugu badan ee la isticmaalo. Sida nooc ka mid ah alaabta birta qaab dhismeedka kaarboon, alaabteeda qaraabada ah waa birta ul wareegsan, bar xagasha, iyo qaybaha birta sida I-Beams, H-beams, xaglaha, iyo kanaalada. Hot Rolled ASTM A36 waxay leedahay dusha qallafsan ee alaabta ugu dambeysa, way fududahay in la sii wado sida mashiinka.
Falanqaynta Halabuurka Kiimikada:
ASTM A36 waxay iska leedahay guud ahaan birta kaarboonka hooseeya, badeecada birta leh kaarboon yar oo ka yar 0.3%, aad bay u jilicsan tahay samaynta fudud, mashiinnada, alxanka. Daawaynta kulaylku waxay saameyn yar ku leedahay ASTM A36 walxaha birta ah. Waxaa ku jira walxo kale oo ay ka mid yihiin: manganese, baaruud, fosfooraska iyo silikon. Birta iyo canaasiirtan ayaa si wada jir ah u sameeya hanti farsamo oo gaar ah oo ah ASTM A36, si ka duwan birta aan lahayn nikkel iyo curiyaha chromium, ma muujinayso iska caabin daxalka wanaagsan. Haddii aad u baahan tahay hanti u adkaysata daxalka, in lagu rinjiyeeyo lakabka dahaadhku waa doorasho wanaagsan.

Falanqaynta Hantida Jirka:
Alaabta birta ah ee A36 ee u qalma waa inay lahaataa awoodaha ugu dambeeya ee xajinta inta u dhaxaysa 58,000 ilaa 79,800 psi. Ma aha tiro sax ah sababtoo ah waxay saamaysay ka kooban kiimikada iyo habka wax soo saarka. Tijaabada xajinta, ASTM A36 birta birta ah waxay ku kordhin kartaa ilaa 20% dhererkeeda asalka ah. Waxa kale oo ay ku tusinaysaa awoodda saamaynta fiican ee heerkulka qolka.
