Q355 Txheej txheem cej luam
Q355 steel yog cov hlau tsis tshua muaj zog, muaj zog hlau uas siv rau hauv cov qauv welded txhawb kev ntxhov siab thiab hnyav hnyav. Q hais txog qhov taw tes tawm, thaum tus lej 355 qhia nws lub zog tawm los. Nws kuj hloov Q345.
Q355 Cov khoom sib npaug
Q355 tuaj yeem hloov nrog cov ntaub ntawv sib npaug, suav nrog A572 Qib 50 Tebchaws ATA ASTM, Q355 Tuam Tshoj GB / T, thiab Spfc 590 Jis.
Cov yam ntxwv ntawm Q355
Q355 steel yog cov qauv hlau nrog ib qho txiaj ntsig lub zog ntawm 345 MPa thiab tensile lub zog ntawm 450 mpa. Nws muaj kev ua yeeb yam zoo kawg li thiab lub zog compressive, uas tuaj yeem siv los tsim cov roj av siab muaj peev xwm tsawg dua 500 plhom. Q355 tseem muaj txheej tiv thaiv ntawm 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.
Kev siv Q355
Q355 steel muaj cov khoom siv kho kom zoo nkauj, zoo nkauj zoo nkauj, thiab txaus corrosion tsis kam. Nws tuaj yeem siv los tsim thiab tsim cov roj av tso tsheb hlau luam, cov nkoj siab, cov nkoj siab, cov nkoj, cov khoom siv hluav taws xob siab. Q355 tseem muaj dav siv los ua cov thawv xa khoom, cov khoom pov tseg huab cua, cov thawv pov tseg, cov thawv muab cov ntaub ntawv, thiab cov cuab yeej siv.
