Muaj peev xwm Q355B hlau siv rau hauv kev tsim cov khoom lag luam hauv tsheb?
Q355B steel can be used in the manufacture of some automotive parts, but its application needs must be comprehensively considered based on the specific performance requirements of the automotive parts (such as strength, formability, weldability, and lightweighting). Cov hauv qab no yog cov ncauj lus kom ntxaws:
1. Yog Q355B kev ua tau zoo haum rau qhov chaw tsheb?
Lub zog zoo: Q355B tau muaj txiaj ntsig lub zog ntawm ntau dua los yog sib npaug {}}} lub zog qis -} alieclo. Qhov no yog zoo dua rau qhov qis qis - pupbon steels (xws li ib co automotive qes {}} lub zog steels (xws li HSLA hlau). Nws tuaj yeem ua tau raws li cov kev cai ntawm cov khoom siv siab thauj (xws li load {{} Cov kabmob qauv qauv thiab anti {14} {sib nraus}.
Zoo weldability: nrog cov ntsiab lus carbon qis (tsawg dua los yog sib npaug ntawm cov txheej txheem vuam uas siv rau kev ua lag luam vuam (xws li arc vuam (xws li arc vuam (xws li arc vuam thiab Kuj Vuam thiab Kuj Vuam). Kev muaj mob nruab nrab: elongation ntau dua lossis sib npaug li 22%. Thaum muaj qee qhov txias - Ua haujlwm muaj peev xwm ua haujlwm, qhov no qis dua cov hlau sib sib zog nqus (piv txwv li, spcc). Nws yog qhov tsis haum rau kev sib sib zog nqus - teeb kev nrog cov kab nkhaus ua (piv txwv li, lub cev panels).
2. Cov khoom siv tsheb uas haum
Chassis cov qauv sib xyaw: xws li ncej longitudinal / hla cov tswv cuab, thiab tshem tawm cov kab xev, thiab tshem tawm qhov hnyav ntawm lub tsheb thiab kev cuam tshuam. Lub zog siab ntawm Q355B kom paub meej cov qauv kev ruaj ntseg.
Kev sib tsoo -} Cov hluav taws xob tsis txaus ntseeg: xws li lub qhov rooj cuam tshuam cov thav duab hluav taws xob thaum lub zog sib tsoo. Nws lub zog thiab kev muaj zog (cuam tshuam rau lub zog loj dua los yog sib npaug ntawm 34J ntawm 20 degree) txhim kho kev nyab xeeb.
Kev hnyav {{0 {{{} Dosy} {} {}} kev txwv thiab lwm yam khoom siv
Kev siv cov hlwv qis: Thaum Q355B lub zog yog siab dua cov hlau me me (xws li DP cov ntawv thov sib txawv (uas muaj txiaj ntsig zoo ntawm 400 {} 800 mpa). Hauv kev ua raws li cov neeg caij tsheb thauj neeg caij tsheb, nws yuav hloov los ntawm kev hloov pauv thiab thinner high-zog hlau.
Kev Txwv Cov Txwv: Nws tsis tuaj yeem siv rau qhov uas yuav tsum tau ua kom zoo thiab ncab (xws li hoods thiab lub rooj panels). Cov ntu no feem ntau ua los ntawm txias- rolled lossis galvanized steel muaj zog thiab qis ducility.
Ntsiab lus: Q355B tuaj yeem siv rau thauj khoom {{1} {{{1} premm precision tsim cov tsheb rau cov neeg caij tsheb muaj tsawg. Hauv kev tsim khoom tiag tiag, cov neeg siv tsheb xum nyiam cov qauv kev lag luam tshwj xeeb hauv GB / T 24186), raws li lawv qhov kev ua tau haum rau cov kev xav tau ntawm kev tsim kho tsheb.
