Qhov zoo tshaj plaws ntawm q235 steel
Khoom Description
Q235 steel muaj ntau qhov zoo tshaj plaws uas ua rau nws muaj koob meej thiab siv dav hauv ntau daim ntawv thov. Nov yog qee qhov ntawm nws qhov zoo tshaj plaws:
Tus nqi -Cov
Q235 steel paub txog nws tus nqi -kev ua tau zoo. Nws yog yooj yim muaj thiab dav tsim, uas pab kom nws tus nqi kuj qis dua piv rau lwm hom hlau. Qhov no ua rau nws yog ib qho kev xaiv txaus nyiam rau tej yaam num nrog kev txwv nyiaj txiag.
Weldability zoo heev
Q235 steel muaj qhov zoo tshaj plaws weldability, uas yog qhov zoo tshaj plaws hauv ntau daim ntawv thov. Nws tuaj yeem yooj yim welded siv ntau yam txuj ci, xws li arc vuam, tsis kam vuam, thiab roj vuam. Qhov no tso cai rau kev tsim khoom thiab kev tsim kho kom zoo, txo cov sij hawm sib dhos thiab cov nqi.
Ntau yam
Q235 steel yog ntau yam ntau yam thiab pom kev siv dav hauv kev lag luam thiab kev siv sib txawv. Nws yog feem ntau ua haujlwm hauv kev tsim kho rau cov khoom siv xws li kab teeb, kab, thiab trusses. Nws kuj tseem siv rau hauv kev tsim cov tshuab, cov khoom siv tsheb, cov kav dej, thiab dav dav -cov khoom siv hlau. Lub versatility ntawm Q235 steel ua rau nws haum rau ntau yam ntawm tej yaam num.
Siab Tensile zog
Q235 steel muaj lub zog tensile siab, feem ntau yog li ntawm 370 txog 500 MPa. Lub zog siab no ua rau nws tiv taus cov khoom hnyav thiab muab cov qauv kev ruaj ntseg. Nws muaj txiaj ntsig tshwj xeeb hauv cov ntawv thov uas xav tau lub zog thiab thauj khoom-cov kabmob muaj peev xwm, xws li kev tsim vaj tsev thiab txuas hniav.
