ASTM A514 saxan bir ah

ASTM A514 darajada A waa nooc ka mid ah ASTM A514 steel. Guryaha la xusay waxay ku habboon yihiin xaaladda la demiyay iyo kuwa xanaaqsan. Baararka garaafyada ee kaadhadhka guryaha ee hoose waxay barbardhigaan ASTM A514 darajada A iyo: Biraha daawaha la sameeyay ee isla qaybta (sare), dhammaan birta birta ah (dhexe), iyo kaydka xogta oo dhan (hoose).

Saxanka birta A514 Fasalka A waxa uu ku hoos jiraa qeexida heerka birta ee xoogga dhalidda sare ASTM A514/A514M.A514GrA 690Mpa ee dhumucda ka hooseeya 65mm, iyo 620 Mpa dhumucdiisuna waxay ka sarraysaa 65mm, xoogga xajin waa in ay ahaataa gudaha 760-895 Mpa. Soo saaraha ayaa laga yaabaa inuu dib u kululeeyo taarikada ku guuldareysta inay buuxiyaan shuruudaha hantida farsamada ee qeexitaankan marka la duubayo saxanka birta kacsan ee A514GrA. Dhammaan tijaabooyinka hantida makaanikada waa in lagu celiyaa marka alaabta dib loo soo gudbiyo si loo eego.
