Cov ntsiab lus
Dab tsi yog lub ntsiab lus ntawm ultra-siab zog steel?
Hom ntawm ultra-siab zog steel
Vim li cas lub ntsiab lus ntawm "Ultra High Strength Steel (UHSS)" tseem ceeb
Vim li cas lub tsheb siv AHSS / UHSS steel?
Ultra-high-strength steel (UHSS) nyob rau hauv tsheb yog ua tau siab heev high-strength steel (AHSS), uas muaj ntau zog tensile zog. Hauv lwm lo lus, UHSS (aka "High Strength Steel") yog ib pawg ntawm AHSS steel qeb.
Dab tsi yog lub ntsiab lus ntawm ultra-siab zog steel?
Keeb kwm, World Auto Steel tau siv cov ntsiab lus hauv qab no raws li lub zog tensile yam tsawg kawg nkaus:
Ntau dua lossis sib npaug rau 550 MPa TS: Advanced High Strength Steel (AHSS)
Ntau dua lossis sib npaug rau 780 MPa TS: Ultra-siab zog steel (UHSS)
Ntau dua lossis sib npaug ntawm 1000 MPa lossis 1 GPa TS: GigaPa steel
Txawm li cas los xij, World Auto Steel's 2021 AHSS Steel Daim Ntawv Qhia Qhia tau teeb tsa lub zog tensile yam tsawg kawg nkaus rau AHSS steel ntawm 440 MPa, thaum lees paub tias tsis muaj kev pom zoo ntawm qib tensile zog rau UHSS steel. Tej zaum qhov tsawg dua siv lo lus "GigaPascal" yuav nyiam vim nws cov ntsiab lus tsis meej: steel nrog lub zog tensile ntawm 1000 MPa lossis siab dua.
Hom ntawm ultra-siab zog steel
Cov ntaub ntawv hlau metallographic uas tuaj yeem ncav cuag UHSS lub zog muaj xws li:
Martensitic hlau (M)
Kub tsim steel (PHS, tseem hu ua hardened boron steel, los yog "kub stamped" steel)
Complex theem steel (CP)
High ntug ductility steel (HE)
Dual Phase Hlau (DP)
Dual theem steel (DH) nrog siab formability
Ferritic bainitic hlau (FB)
Vim li cas lub ntsiab lus ntawm "Ultra High Strength Steel (UHSS)" tseem ceeb
Yog tias tsis muaj kev lees paub thoob ntiaj teb cov ntsiab lus ntawm ultra-high-strength steel, vim li cas lo lus tseem siv? Cov lus teb yog tias "UHSS" yog qhov muaj txiaj ntsig zoo rau ob qho tib si steelmakers thiab automakers vim nws succinctly hais txog cov khoom muaj zog siab zog siab.
Raws li lub zog ntawm UHSS steel tseem nce ntxiv, tib neeg yuav tsum xav txog yuav ua li cas los tsim nws rau hauv cov khoom siv tsheb, suav nrog kev kwv yees lub caij nplooj ntoo hlav thiab lwm yam teeb meem. Ntawd yog, feem ntau cov teeb meem tsim tuaj yeem daws tau los ntawm kev xaiv UHSS steel nrog cov khoom tsim nyog, tsim kev simulation, cov pwm tsis raug thiab cov qauv tsim tsheb.
Vim li cas lub tsheb siv AHSS / UHSS steel?
AHSS / UHSS steel muaj ntau txoj hauv kev automakers tuaj yeem ua kom zoo dua lawv lub cev-hauv-dawb tsim: Thaum AHSS / UHSS steel yog los ntawm CO2 tsis tshua muaj zog steel mills los yog siv cov hlau siv los ua raw khoom, nws muab kev tiv thaiv zoo dua, zoo dua Lightweighting. thiab zog efficiency, siab dua tsheb muaj peev xwm thiab kev ua tau zoo, thiab txhim khu kev ruaj ntseg.
Txhim kho kev cuam tshuam thiab kev nyab xeeb
Advanced high-strength thiab ultra-high-strength steels tso cai rau koj kom ua tau raws li tshiab, nruj kev lag luam qauv los yog muab ib tug ntxiv (thiab kev ua lag luam-tsim nyog) degree ntawm kev ruaj ntseg khoom.
Lub teeb, lub zog txuag
Txhua txhua xyoo, automakers qhia ntau thiab ntau dua siab-lub zog thiab ultra-high-strength steels raws li lawv ntxiv optimize lub tsheb lub teeb yuag kev ua tau zoo thaum ua tau raws li kev sib tsoo cov qauv nruj. Lub teeb yuag nrog AHSS thiab UHSS steel tuaj yeem pab koj lub tsheb ua tau raws li tsoomfwv cov kev xav tau yav tom ntej, nrog rau cov neeg siv khoom tam sim no xav tau cov nqi hluav taws xob qis dua.
Txhim kho tsheb muaj peev xwm thiab kev ua haujlwm zoo
Kev hloov kho rau AHSS / UHSS steel qib tuaj yeem ua rau koj lub tsheb muaj zog dua, nrog rau kev them nyiaj ntau dua thiab ua haujlwm zoo dua. Advanced high-strength thiab ultra-high-strength steels kuj tseem tuaj yeem ua rau kom muaj zog torsional los txhim kho tsheb tuav thiab teb. Tsis tas li ntawd, lawv muab ntau qhov chaw sab hauv (rau kev xaim, cov khoom siv hluav taws xob, thiab lwm yam) los ntawm kev hloov cov ntaub ntawv tuab nrog AHSS / UHSS hlau nyias.
Txhim kho kev ruaj ntseg
Txawm hais tias aluminium thiab carbon fiber cov ntaub ntawv muaj zog thiab hnav, lawv kuj yog cov khoom siv CO2 siab thiab nyuaj rau rov ua dua dua li cov hlau. Thaum xaiv cov khoom siv, nug koj tus kheej seb koj qhov kev xaiv puas zoo ib yam nrog koj cov neeg siv khoom lub hom phiaj sustainability.
Tam sim no, koj ua tautiv tauj peb, GNEE tsim AHSS / UHSS qib steel, uas raug nqi 40% mus rau 400% qis dua cov ntaub ntawv muaj zog ntawm cov hlau tsis muaj hlau.
