A572 Qib 65 yog lub zog siab, qis-alloy (HSLA) cov qauv steel phaj raws li ASTM A572 / A572M tus qauv specification. Nws yog tsim los muab lub zog zoo heev thiab weldability thaum tuav cov formability zoo.
Qib 65" qhia tias cov hlau no muaj qhov tsawg kawg nkaus lub zog ntawm 65 ksi (450 MPa) thiab lub zog tensile yam tsawg kawg nkaus ntawm 80-90 ksi ({4}} MPa). yuav tsum tau txo qhov hnyav thiab muaj zog ntxiv.
A572 Qib 65 HSLA structural steel phaj feem ntau yog siv rau hauv kev tsim vaj tsev thiab kev tsim vaj tsev nyob qhov twg yuav tsum muaj lub zog-rau-qhov hnyav piv. Qhov qis alloy muaj xws li cov ntsiab lus xws li carbon, manganese, phosphorus, sulfur, silicon, vanadium, niobium thiab me me ntawm lwm cov alloys. Cov ntsiab lus alloying no pab txhawb rau tag nrho cov khoom siv kho tshuab thiab kev ua haujlwm ntawm cov hlau.
Cov phaj hlau no tuaj yeem ua tiav los ntawm kev txiav, khoov, vuam, thiab lwm yam kev tsim khoom kom tau raws li qhov kev xav tau tshwj xeeb.A572 Qib 65 steel yog siv dav hauv cov txuas hniav, tsev, tshuab, thiab lwm yam kev thauj khoom uas yuav tsum tau muaj zog thiab ua haujlwm ntev. .
