Dab tsi kev lag luam yog S235JRH hlau kav hlau feem ntau siv rau?
S235JRH hlau kav hlau tau siv dav siv hauv kev tsim kho, tshuab tsim khoom, choj tshuab, khoom siv ua liaj ua teb, thiab cov ntawv thov dav dav. Hauv kev tsim kho kev tsim kho, feem ntau nws siv rau load - Cov kabmob hlau ua xws li cov txheej txheem steel hlau, ru tsev trusses, thiab cov kab ntawv txhawb nqa. Hauv kev tsim tshuab raug kev lag luam, nws zoo heev formability yog siv los tsim cov ntawv sib txuas, cov cuab yeej cuab tam, thiab lwm yam. Vim nws tus nqi - ua hauj lwm zoo thiab ua raws li cov khoom muaj txiaj ntsig zoo hauv cov phiaj xwm infrastructure hauv EU lub teb chaws. Nws kuj tseem siv tau rau cov qauv ib ntus xws li scaffolding, tab sis muaj xeb kev kho mob yog yuav tsum tau.
Vim li cas S235JRH steel yeeb nkab nyiam hauv kev tsim kho kev tsim kho?
Kev tsim kho kev tsim kho kev xaiv s235jrh vim nws lub zog sib luag (235 mpaelity weldability) thiab zoo} nplai stand hlau qauv vuam. Nws cov peev txheej muaj cov pa roj carbon qis txo qhov kev pheej hmoo ntawm weld cracking thiab eases tsim kev nyuaj. Tus txheej txheem txias ua kom muaj kev sib txuas siab, yooj yim kom yooj yim sib txuas rau lwm cov. Tsis tas li ntawd, ua raws li cov EN 10210/10219 cov qauv ua kom cov khoom siv zoo sib xws thiab ua raws li EU cov cai tsim tsev. Nyob rau hauv cov nqe lus ntawm tus nqi, S235JRH yog kev lag luam ntau dua li siab- lub zog steel thiab haum rau dav dav {{} bearing xav tau.
Yog s235jrh haum rau tsawg -} qhov chaw ib puag ncig?
Qhov kev cuam tshuam nyuaj ntawm s235jrh yog kuaj ntawm 0 degree, ua rau nws haum tsuas yog rau kev mob me- sov qhov chaw nyob (xws li European Winters). Rau ntev -}}}}}}}}}} {}} Cov hlau kub xws li S235J0 lossis S355J2. Thaum siv nyob rau hauv cov cheeb tsam txias, qhov qis- kub todlight ntawm welded pob qij txha yuav tsum tau tshuaj ntxiv. Kev tsis kho S235JRH cov yeeb nkab tej zaum yuav muaj kev sib tsoo ntawm qhov kub me me. Rau cov ntawv thov tsawg-ntsuas kub, muaj kev nyab xeeb yuav tsum tau koom rau hauv cov qauv tsim thiab cov txheej txheem vuam cov txheej txheem yuav tsum ua kom nruj me ntsis.
Cov qib steel tau siv hauv kev thauj khoom - cov kabmob qauv?
S235JRH tuaj yeem siv rau nruab nrab - phoo ntawv qauv, xws li cov pob Hoobkas, thiab qis}} Rose tsev txhawb nqa. Nws cov txiaj ntsig lub zog ntawm 235 MPa txaus kom tau raws li cov kev xav tau feem ntau cov khoom siv qub. Txawm li cas los xij, rau high -}}} {{} {{} lub zog s355 series yuav haum ntau. Ua ntej siv, cov qauv suav yuav tsum txheeb xyuas nws load - bearing muaj peev xwm thiab kev thauj khoom tsis zoo. Welded sib koom ua ke tsim yuav tsum ua raws li cov qauv hlau tshwj xeeb xws li EN 1993-1-1.
Dab tsi yog daim ntawv thov piv txwv ntawm S235JRH hauv kev tsim khoom lag luam?
Nyob rau hauv kev lag luam automotive, s235jrh yog feem ntau siv rau tsis-} Cov kab teeb cig, cov thawv thauj khoom, thiab cov thawv thauj khoom thiab cov thawv thauj khoom. Its cold-forming properties make it suitable for manufacturing lightweight components with complex cross-sections. Vim yog lub zog siab yuav tsum muaj ntawm cov tsheb, S235JRH feem ntau tsis siv nyob rau hauv kev nyab xeeb {{} li anti - kev sib tsoo nqaj). Nyob rau hauv lub tsheb thauj khoom lag luam sector, galvanizing tuaj yeem txhim kho corrosion tsis kam. Piv rau cov hlau tshwj xeeb, nws muaj cov nqi qis dua, tab sis kev txwv kev qaug zog yuav tsum raug sau tseg.
