A992 Qib yog qib ntawm cov qauv hlau feem ntau siv hauv kev tsim kho thiab engineering. Hom hlau no feem ntau ua tau raws li ASTM (American Society for Testing and Materials) cov qauv, tshwj xeeb, A992 yog qib ASTM A992. ASTM A992 yog ib qho kev qhia tshwj xeeb rau kev tsim khoom kub-kuav los tiag steel qauv profiles. Cov profiles no feem ntau siv rau hauv cov qauv xws li cov tsev thiab txuas hniav. A992 Qib steel muaj qee qhov kev xav tau ntawm lub zog thiab kev ua haujlwm vuam, yog li nws feem ntau siv rau hauv cov khoom siv uas dais loj hauv engineering, xws li kab teeb, kab, thiab lwm yam.
A992 Qib steel feem ntau muaj lub zog tensile zoo thiab lub zog tawm los, nrog rau kev ua haujlwm zoo corrosion, tso cai rau nws ua haujlwm ruaj khov hauv ntau qhov chaw ib puag ncig. Hom hlau no feem ntau muaj qhov zoo weldability thiab tuaj yeem ua tau raws li qhov xav tau ntawm vuam hauv cov haujlwm engineering.
Feem ntau, A992 Qib steel yog cov khoom siv feem ntau siv hauv kev tsim kho thiab engineering. Nws muaj lub zog zoo, vuam kev ua tau zoo thiab corrosion kuj, thiab haum rau ntau yam khoom siv nrog ntau dua.
