Dual theem steel (DP steel)
Cov yam ntxwv ntawm kev ua tau zoo: tsis muaj yield elongation, tsis muaj chav kub aging, tsis tshua muaj yield-rau-lub zog piv, siab ua hauj lwm hardening Performance index thiab siab ci hardening nqi.
Cov ntawv thov: DP series high-strength steel yog tam sim no nyiam steel hom rau cov qauv thiab yog dav siv nyob rau hauv cov yam ntxwv qhov chaw, reinforcements thiab anti-kev sib tsoo qhov chaw. Piv txwv li, lub tsheb hauv qab hla cov tswv cuab, cov ntsia hlau, cov khoom tiv thaiv kev sib tsoo, cov khoom siv tiv thaiv kev sib tsoo, cov khoom siv hluav taws xob, thiab lwm yam.
Complex theem steel (CP steel)
Cov yam ntxwv ua tau zoo: cov nplej zoo thiab muaj zog tensile siab. Piv nrog dual-theem steels nrog tib theem ntawm tensile lub zog, nws lub zog tawm los yog ntau dua. Nws muaj kev ua tau zoo bending, siab qhov nthuav dav kev ua tau zoo, siab zog nqus peev xwm thiab zoo heev flanging kev ua haujlwm.
Daim ntawv thov: chassis ncua kev kawm ntawv, B-pillars, bumpers, rooj rails, thiab lwm yam.
Phase transformation induced plasticity steel (TRIP steel)
Cov yam ntxwv ntawm kev ua tau zoo: Cov qauv muaj cov austenite khaws cia thiab muaj cov qauv zoo. Thaum lub sij hawm tsim cov txheej txheem, cov khaws cia austenite yuav maj mam hloov mus rau hard martensite, uas muaj txiaj ntsig zoo rau kev deformation. TRIP steel kuj muaj cov yam ntxwv ntawm kev sib tsoo siab absorbing zog, siab zog yas khoom thiab siab n tus nqi.
Cov ntawv thov: qhov chaw uas muaj cov qauv sib txawv, xws li B-pillar reinforcement plates, pem hauv ntej longitudinal beams, thiab lwm yam.
Martensitic hlau (MS steel)
Cov yam ntxwv ntawm kev ua tau zoo: siab yield-rau-lub zog piv, siab tensile lub zog, kuj tsis tshua muaj elongation, yuav tsum tau them sai sai rau qhov nyiam ntawm ncua kev tawg. Nws muaj cov yam ntxwv ntawm kev sib tsoo siab absorbing zog, siab zog yas khoom thiab siab n tus nqi.
Cov ntawv thov: txias stamping ntawm qhov yooj yim thiab yob tsim qhov chaw nrog ib qho kev sib tshuam, xws li cov pob, cov sill reinforcements thiab cov khoom tiv thaiv kev sib tsoo hauv cov qhov rooj sab.
Quenched Ductile Steel (QP Steel)
Cov yam ntxwv ntawm kev ua tau zoo: Siv martensite raws li theem matrix thiab siv TRIP nyhuv ntawm khaws cia austenite thaum lub sij hawm deformation, nws muaj peev xwm ua tau ntau dua kev ua haujlwm hardening muaj peev xwm, yog li nws muaj ntau dua plasticity thiab formability dua tib theem ntawm ultra-high-strength steel.
Cov ntawv thov: Haum rau kev nyab xeeb ntawm lub tsheb thiab cov khoom siv nrog cov duab sib txawv, xws li A thiab B pillar reinforcements, thiab lwm yam.
Twin induced plasticity steel (TWIP steel)
Cov yam ntxwv ntawm kev ua tau zoo: TWIP steel yog tag nrho austenitic steel nrog siab C, siab Mn thiab siab Al Cheebtsam. Muaj peev xwm ua haujlwm siab heev tuaj yeem ua tiav los ntawm kev sib tw ntxaib-induced dynamic refinement. TWIP steel muaj ultra-siab zog thiab ultra-siab plasticity, nrog lub zog-yas ntim ntau tshaj 50Gpa%.
Cov ntawv thov: TWIP steel muaj qhov zoo tshaj plaws formability thiab ultra-siab zog, thiab yog haum rau qhov chaw uas yuav tsum tau cov ntaub ntawv siab thiab bulging zog, xws li complex-zoo li tus automotive kev nyab xeeb qhov chaw thiab cov yam ntxwv.
Boron steel (PH hlau los yog B steel)
Cov yam ntxwv ntawm kev ua tau zoo: lub zog ultra-siab (lub zog tensile ntau dua 1500MPa), txhim kho kev sib tsoo zoo, lub cev hnyav; complex duab ntawm qhov chaw, zoo formability; siab qhov tseeb.
Daim ntawv thov: kev nyab xeeb cov qauv, xws li pem hauv ntej thiab nram qab bumpers, A-pillars, B-pillars, center tunnels, thiab lwm yam.
Steel siv nyob rau hauv automotive kev lag luamyuav tsum ua tau raws li cov hauv qab no: cov pa roj carbon tsawg (siab weldability), tus nqi qis (tsis tshua muaj alloy ntxiv), siab formability, thiab yooj yim sib dhos thiab txij nkawm.
