High-strength Steel Rau Tsheb

GNEE Steel automotive hlau

Lub hauv paus ntawm kev tsim tsheb niaj hnub no yog kev nyab xeeb thiab kev tiv thaiv ib puag ncig, thiab lub cev xav tau "ua kom muaj zog thiab txo qhov hnyav". Advanced high-strength steels yog booming nyob rau hauv cov ntsiab lus no thiab yog dav siv nyob rau hauv cov qauv thiab kev nyab xeeb qhov chaw ntawm lub tsheb lub cev.

 

Hom muaj zog steels siv nyob rau hauv tsheb

1. DP steel, duplex steel

2. CP steel, complex theem steel

3. TRIP steel, theem transformation-induced plasticity steel

4. MS steel, martensitic hlau

5. QP steel, quenched thiab muab faib steel

6. TWIP steel, ntxaib induced plasticity steel

7. PH steel lossis B steel, stamping hardening / boron steel

DP steel hlau

Cov yam ntxwv: tsis muaj yield elongation, tsis muaj aging ntawm chav tsev kub, tsis tshua muaj yield ratio, siab ua hauj lwm hardening Performance index, siab ci hardening nqi.

Daim ntawv thov: DP series high-strength steel yog cov hlau nyiam rau cov khoom siv, uas yog siv dav hauv cov khoom siv, kev txhawb zog thiab kev sib tsoo. Piv txwv li, underbody beams, rails, crash bars, crash bar reinforcement structures, thiab lwm yam.

Chia Tai Steel

Nta: zoo nplej, siab tensile zog. Lub zog tawm los yog qhov siab dua li ntawm duplex steels nrog tib lub zog tensile. Nws muaj kev ua tau zoo bending, siab qhov nthuav dav kev ua tau zoo, siab zog nqus peev xwm thiab zoo heev flanging txoj kev ua haujlwm.

Daim ntawv thov: Chassis ncua kev kawm ntawv, B-pillars, bumpers, rooj rails, thiab lwm yam.

TRIP Steel

Yam ntxwv: Muaj cov seem austenite nyob rau hauv cov ntaub so ntswg, nrog zoo formability. Thaum lub sij hawm tsim cov txheej txheem, cov residual austenite maj mam hloov mus rau hauv hard martensite, uas yog conducive rau uniform deformation. TRIP steel kuj muaj cov yam ntxwv ntawm kev ua haujlwm siab nqus lub zog, siab zog ntawm cov khoom yas, thiab siab n-tus nqi.

Daim ntawv thov: qhov chaw nrog cov qauv complex, xws li B-pillar stiffeners, pem hauv ntej longitudinal kab teeb, thiab lwm yam.

MS hlau

Cov yam ntxwv: High yield ratio, siab tensile zog, kuj tsis tshua muaj elongation yuav tsum tau them sai sai mus rau lub nyiam ncua kev tawg. Nws muaj cov yam ntxwv ntawm kev cuam tshuam siab nqus zog, siab zog ntawm cov khoom yas thiab siab n tus nqi.

Daim ntawv thov: Txias stamping thiab cross-section ntawm cov khoom yooj yim yog ib qho yob-tsim qhov chaw, xws li bumpers, sill stiffeners, tsoo tuav nyob rau hauv lub qhov rooj.

QP hlau

Cov yam ntxwv: Nrog martensite raws li theem matrix, TRIP cov nyhuv ntawm residual austenite thaum lub sij hawm deformation tuaj yeem ua tiav ntau dua kev ua haujlwm hardening peev xwm, yog li nws muaj ntau dua plasticity thiab formability dua ultra-high-strength steels ntawm tib qib.

Daim ntawv thov: Nws yog tsim rau automotive kev nyab xeeb qhov chaw thiab cov khoom siv nrog cov duab nyuaj, xws li A, B pillar reinforcements.

PH steel los yog B steel

Cov yam ntxwv: ultra-siab zog (lub zog tensile siab tshaj 1500MPa), zoo txhim kho kev sib tsoo, lub cev hnyav; Cov duab ntawm cov khoom yog complex thiab formability yog zoo; Siab qhov tseeb.

Daim ntawv thov: Kev nyab xeeb cov qauv, xws li: pem hauv ntej thiab nram qab bumpers, A-pillar, B-pillar, nruab nrab channel, thiab lwm yam.

TWB steel

Nta: TWIP steel yog ib yam ntawm tag nrho-austenitic steel nrog siab C, siab Mn thiab siab Al muaj pes tsawg leeg. Nrog rau qhov dynamic refinement tshwm sim los ntawm tus ntxaib, muaj peev xwm ua haujlwm siab heev tuaj yeem tau txais. TWIP steel muaj ultra-siab zog thiab ultra-siab plasticity, thiab lub zog yas khoom tuaj yeem ncav cuag ntau tshaj 50Gpa%.

Daim ntawv thov: TWIP steel muaj qhov zoo tshaj plaws formability thiab ultra-siab zog, thiab yog haum rau qhov chaw uas yuav tsum tau siab tensile thiab o cov khoom ntawm cov ntaub ntawv, xws li automotive kev nyab xeeb qhov chaw thiab cov khoom siv nrog complex duab.
