A572 yog ib qho ntawm cov qib siab tshaj plaws ntawm cov qauv steel. Vim li cas? Vim tias nws muab kev sib xyaw ua ke zoo tshaj plaws ntawm lub zog siab, siab ntswj toughness, zoo ductility, thiab zoo weldability.
Nws yog siab -lub zog qis alloy (HSLA) cov qauv hlau nrog tsib qib sib txawv. A572 qib 50 qhia tau hais tias lub zog tawm ntawm 50,000 psi thiab lub zog tensile kawg ntawm tshaj 65,000 psi. Nws yog siv thoob plaws hauv kev lag luam tab sis nquag pom hauv kev tsim vaj tsev, kev lag luam tsheb thauj mus los, thiab kev lag luam architecture.
A572-50 Kabmuab kev txhim kho lub zog thaum piv rau lawv qhov hnyav. Raws li qhov tshwm sim, cov khoom qib no tau hloov pauv sai sai rau lwm cov khoom siv kub dov steel qib raws li de facto steel beam. Ob leeg S thiab W A572-50 kab teeb tuaj yeem dub, galvanized, lossis primed.
A572-50 rawskuj tau pom dav dav hauv kev tsim vaj tsev dav dav rau tib yam vim li cas -lawv muab qhov muaj zog ntau dua ntawm qhov hnyav dua li lwm cov khoom lag luam steel channel qib. Ob Txoj Cai Raws Cai thiab MC Channels yuav muaj qhov tsawg kawg nkaus qhov tob ntawm 3 ".
A572-50 Bar Angles, uas tuaj yeem raug xa mus rau lub kaum ntse ntse hlau, lub kaum sab xis steel, L- cov hlua khi, cov seem steel, lossis lub kaum sab xis, yog cov khoom kub dov HSLA. Malleability yog ib qho ntawm cov yam ntxwv tseem ceeb ntawm cov kaum sab xis, raws li lawv feem ntau siv rau kev txhawb nqa thiab kev tsim kho kom ruaj khov rau cov ces kaum thiab kev txhawb nqa dav dav rau tej yam xws li txuas hniav thiab archways. Txhua lub kaum sab xis muaj L-zoo li tus hla ntu, thiab thaum lub kaum sab xis 90℃feem ntau, lawv tuaj yeem tsim los rau cov neeg siv khoom tshwj xeeb nrog qhov ntev sib npaug lossis tsis sib npaug.
