Q235 Qib Cov Khoom Piav Qhia
Raws li GB/T {{0}}} tus qauv, carbon structural steel Q235 tau muab faib ua plaub pawg raws li cov khoom siv hlau zoo: A, B, C, thiab D. Cov tshuaj pleev ib ce ntawm Q235A, B, C, thiab D txawv. Cov sulfur concentration ntawm A, B, C, thiab D poob zuj zus, thaum phosphorus cov ntsiab lus ntawm A thiab B yog tib yam, ua raws li ntawm C, thiab phosphorus theem ntawm D yog qis tshaj. Cov qib sib txawv ntawm Q235A, Q235B, Q235C, thiab Q235D sib haum rau qhov sib txawv ntawm qhov kub thiab txias. A qhia tias tsis muaj kev cuam tshuam, B siab dua 20 degrees, C siab dua 0 degrees, thiab D siab dua -20 degrees.
Weldability
Q235 steel muaj zog weldability thiab tej zaum yuav yooj yim welded siv cov txheej txheem xws li arc, tsis kam, thiab roj welding. Cov yam ntxwv no ua rau kev tsim khoom thiab koom nrog Q235 steel Cheebtsam.
Ductility thiab Formability
Q235 steel muaj ductility zoo heev, tso cai rau cov yas deformation yam tsis muaj pob txha. Cov yam ntxwv no ua rau yooj yim shaping, sib sau, thiab khoov thaum lub sij hawm muaj txheej txheem.
Machineability
Q235 steel muaj zog machinability, ua rau nws haum rau raug machining kev lag luam xws li txiav, drilling, thiab milling.
Corrosion Resistance
Thaum Q235 steel tsis yog qhov muaj kev tiv thaiv corrosion, nws tuaj yeem tiv thaiv corrosion los ntawm ntau txoj kev, xws li siv cov txheej txheem los yog siv cov galvanized lossis stainless hlau versions ntawm Q235.
Nws yog ib qho tseem ceeb kom nco ntsoov tias cov khoom tshwj xeeb ntawm Q235 steel tuaj yeem hloov pauv raws li kev kho cua sov, cov txheej txheem tsim khoom, thiab cov khoom sib txawv. Yog li ntawd, nws yog qhov zoo tshaj plaws los xyuas qhov tsim nyog specifications thiab cov qauv rau cov ntaub ntawv meej thiab cov ncauj lus kom ntxaws rau cov ntawv thov tshwj xeeb.
