Q235 Txheej txheem cej luam
Q235 yog ib qho yooj yim carbon structural steel uas yog siv thoob plaws hauv Suav teb. Nws tseem hu ua Q235A, Q235B, Q235C, thiab Q235D. Txij li nws yog cov hlau me me, nws yog siv hauv kev tsim khoom yam tsis muaj kev kho cua sov. Q qhia qhov taw tes tawm los, thiab 235 qhia tias lub zog tawm los. Nws muaj zoo plasticity thiab weldability.
Q235 Cov khoom sib npaug
Q235 steel tuaj yeem hloov nrog cov khoom sib npaug uas suav nrog A36 USA ASTM, Q235 Tuam Tshoj GB / T, thiab SS400 Nyab Laj / Nyiv JIS.
Cov yam ntxwv ntawm Q235
Raws li cov thickness ntawm cov khoom nce, Q235 tus nqi tawm los txo. Vim nws cov ntsiab lus ntawm cov pa roj carbon ntau, qhov kev ua tau zoo thiab tsim nyog. Q235 kuj zoo sib xws hauv lub zog, vuam, thiab yas. Feem ntau, nws yog dov rau hauv lub phaj steel, pas nrig, bar, los yog lub kaum sab xis ncej. Nws yog feem ntau siv hauv engineering thiab kev tsim kho kev lag luam.
Cov khoom siv hlau Q235 yog raws li PRC cov qauv. Cov pa roj carbon steel rau cov haujlwm tshwj xeeb thiab cov hom phiaj, xws li cov tubrog nkoj thiab choj hlau, feem ntau yog siv cov qauv hlau qhia. Txawm li cas los xij, tsab ntawv qhia txog lub hom phiaj thiab lub hom phiaj yog suav nrog thaum kawg ntawm qib steel.
Thaum Q235 qib steel phaj muaj cov khoom siv qis dua li cov ntaub ntawv A36, cov ntaub ntawv no feem ntau tuaj yeem hloov tau rau ib leeg, tsuav yog tsis muaj qhov tshwj xeeb thiab xav tau kev koom tes. Yog tias tsuas yog rau cov khoom siv cov khoom siv kho tshuab, nws feem ntau lees paub tias Q235 thiab A36 zoo ib yam li cov khoom siv roj carbon zoo.
Kev siv ntawm Q235
Tsis tsuas yog Q235 muaj qhov toughness, weldability, thiab cov yas zoo heev, nws khaws lub zog thaum muab kev ua haujlwm txias-bending zoo. Nws yog qhov zoo tshaj plaws rau cov khoom siv welded, nrog rau cov tsev tsim khoom, steel tuav, yees, boilers, txuas hniav, thawv, tsheb, thiab lwm yam. Q235 tseem tuaj yeem siv los ua cov khoom siv kho tshuab, xws li cov khoom muag, cov pas nrig, cov txiv ntseej, cov pas txuas txuas, cov hlua khi, thiab lwm yam khoom siv. Q235 thiab qib sib txawv ntawm cov hlau phaj tuaj yeem raug txiav rau qhov tshwj xeeb.
