Q235 H-beam yog ib qho zoo tib yam carbon structural steel siv thoob plaws hauv Suav teb. Nws tseem hu ua Q235A, Q235B, Q235C thiab Q235D. Txij li nws yog cov hlau tsis tshua muaj carbon steel, nws tsis xav tau kev kho cua sov hauv kev tsim khoom. q qhia txog qhov taw tes tawm los thiab 235 qhia txog lub zog tawm los. Nws muaj zoo plasticity thiab weldability.

Q235 Qib Cov Qauv Hlau H Beam Khoom Paub meej
Hauv GB / T {{{0}}} tus qauv, carbon structural steel Q235 H zoo li tus hlau raug faib ua plaub qib: A, B, C thiab D raws li cov khoom siv hlau zoo.Cov tshuaj muaj pes tsawg leeg ntawm Q235A, B, C thiab DH seem beam sib txawv. Cov ntsiab lus ntawm sulfur ntawm A, B, C thiab D txo qis hauv qhov kev txiav txim ntawm A, B, C thiab D. Cov ntsiab lus phosphorus ntawm A thiab B yog tib yam, ua raws li C, thiab cov ntsiab lus phosphorus ntawm D yog qhov tsawg kawg nkaus. Cov qib sib txawv ntawm Q235A, Q235B, Q235C thiab Q235D sawv cev rau qhov sib txawv ntawm qhov kub thiab txias; A txhais tau tias tsis muaj kev cuam tshuam, B txhais tau tias siab dua 20 degrees, C txhais tau tias siab dua 0 degrees thiab D txhais tau tias siab dua -20 degrees.
