Q235 Q355 C Channel

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 hlau zoo.

Q355 steel yog cov qauv hlau nrog lub zog tawm ntawm 345 MPa thiab tensile zog ntawm 450 MPa. Nws muaj kev ua tau zoo heev thiab lub zog compressive, uas tuaj yeem siv los tsim cov pa roj siab siab uas muaj tsawg dua 500 litres. Q355 kuj muaj cov txheej txheem tiv thaiv xeb.

Ntxiv rau qhov ua tau zoo, Q355 muaj cov ntsiab lus tshwj xeeb uas tiv thaiv atmospheric corrosion. Vim nws yog cov hlau me me, nws muaj cov ntsiab lus qis carbon. Yog tias cov pa roj carbon ntau ntxiv rau cov hlau, nws yuav raug muab faib ua cov hlau cam khwb cia.

Q355 yog qib tshiab Suav hlau uas tau tsim los hloov Q345. Nws cov khoom siv ceev yog 7.85 g / cm3 thiab muaj peb theem zoo, suav nrog Q355B, Q355C, thiab Q355D. Nws muaj cov cuab yeej zoo heev thiab cov txheej txheem kub thiab txias. Hauv qhov sib piv, nws muaj qhov zoo dua thiab txhim kho cov khoom siv kho tshuab thaum piv rau A36 ASTM steel.
