Q235 steel yam ntxwv
Khoom Description
Q235 carbon steel nthuav tawm ntau tus yam ntxwv uas ua rau nws siv dav hauv ntau daim ntawv thov. Nov yog qee cov yam ntxwv tseem ceeb ntawm Q235 steel:
Cov ntsiab lus carbon tsawgQ235 steel muaj cov ntsiab lus carbon ntawmtsawg dua 0.22%, uas ua rau nws zoo heev weldability thiab formability. Cov ntsiab lus qis carbon kuj txo qhov kev pheej hmoo ntawm brittleness thaum fabrication thiab txhim kho tag nrho cov ductility ntawm cov khoom.
Siab Tensile zogQ235 steel muaj lub zog tensile siab, feem ntau yog li ntawm 370 txog 500 MPa. Lub zog siab no tso cai rau nws tiv taus cov khoom hnyav thiab ua rau nws haum rau cov qauv siv.
Zoo Ductility thiab Toughness:Q235 steel pom zoo ductility, txhais tau tias nws tuaj yeem ncab lossis khoov yam tsis muaj kev tawg. Nws kuj pom zoo toughness, uas ua rau nws nqus tau lub zog thiab tiv thaiv tawg nyob rau hauv kev cuam tshuam los yog dynamic loading tej yam kev mob.
Weldability zoo heev: Q235 steel yog cov vuam zoo heev thiab tuaj yeem yooj yim koom nrog ntau txoj kev vuam, suav nrog arc vuam, vuam vuam, thiab roj vuam. Nws tsim muaj zog thiab txhim khu kev qha welds, tso cai rau kev ua haujlwm zoo thiab kev tsim kho.
Ntau yam: Q235 steel yog ntau yam thiab pom kev siv dav. Nws yog feem ntau siv rau hauv cov khoom siv xws li kab teeb, kab, thiab trusses hauv cov tsev thiab txuas hniav. Nws kuj tseem siv rau kev tsim cov tshuab, khoom siv tsheb, thiab cov khoom siv hlau dav dav.
Corrosion Resistance: Thaum Q235 steel tsis yog qhov muaj zog tiv thaiv corrosion, nws tuaj yeem tiv thaiv corrosion los ntawm txheej txheej, xws li xim lossis galvanizing. Galvanized Q235 steel, piv txwv li, yog coated nrog ib txheej ntawm zinc, muab kev txhim kho corrosion kuj.
Q235 Hardness: Q235 steel muaj ib tug nruab nrab hardness, uas pab rau nws machinability. Nws tuaj yeem txiav tau yooj yim, drilled, thiab machined siv cov cuab yeej thiab cov tswv yim.
Nqi-zoo: Q235 steel yog tus nqi-zoo piv rau ntau lwm hom hlau, ua rau nws nrov rau ntau yam haujlwm thiab kev siv. Nws muaj thiab pheej yig ua rau nws siv dav hauv kev tsim kho thiab kev lag luam.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov yam ntxwv tshwj xeeb thiab kev ua tau zoo ntawm Q235 steel tuaj yeem sib txawv raws li cov yam ntxwv xws li kev kho cua sov, cov txheej txheem ua, thiab muaj cov impurities. Yog li ntawd, nws raug nquahu kom sab laj txog cov kev qhia tshwj xeeb thiab cov qauv rau cov ntaub ntawv meej txog cov qib tshwj xeeb thiab cov ntawv thov.
