Stkr4 {{4 {}} 0}}}}}}}}}}}} thiab stkr490 yog ob qho tib si ntawm cov qauv, conforming rau JIS G3466 tus qauv. Stkr400 muaj qhov siab tshaj plaws cov ntsiab lus carbon ntau ntawm 0.25%, nrog cov txiaj ntsig muaj zog ntawm tsawg kawg 2400 n / mm², ua nws haum rau ntau cov ntawv thov kev tsim qauv. Stkr490, ntawm qhov tod tes, muaj cov ntsiab lus roj carbon ntau tshaj plaws ntawm 0.18% thiab mm² thiab 490 n / mmol thiab 490 n / mak² lub zog rau cov kev sib xyaw siab. Ob cov ntaub ntawv muaj qhov zoo weldability thiab tau siv dav hauv kev ua haujlwm ntawm pej xeem, kos duab, thiab lwm daim qauv txheej txheem.

• Carbon (c): Txo cov ntsiab lus txo cov ntsiab lus hauv stkr49 {1}} ({) piv rau stkr400 (0.25% multi}. Max) feem ntau ua tau zoo dua weldability thiab ductility. Qhov no ua rauStkr490 Qhov tsim nyog rau cov ntawv thov yuav tsum muaj cov qauv vuam txuas ntxiv thiab tsim cov txheej txheem.
• Silicon (si) thiab manganese (mn): Muaj cov ntsiab lus hauvStkr490(mus txog {0. 55% si thiab 1.50% mn) tauTxhim kho lub zog thiab cov tawv nqaij tawv ntawm cov hlau, ua rau nws haum ntau rau kev siv lub zog high-zog.

• Paib thiab tensile lub zog:Stkr490tau ntau dua cov txiaj ntsig tsawg kawg thiab cov kua nplaum tensile piv rau STKR400, ua rau nwsTsim nyog dua rau cov ntawv thov uas yuav tsum tau muaj peev xwm ntau dua cov khoom muaj peev xwm thiab kev ntseeg siab.
• Elongation: Ob qib kawm muaj qhov tsis tshua muaj txiaj ntsig, qhia txog kev sib luag sib xws thiab muaj peev xwm tiv thaiv kev ua haujlwm ua ntej tsis ua haujlwm.

Stkr400:

• Nqi-Zoo: Txo cov ntsiab lus txo cov ntsiab lus thiab cov tshuaj lom neeg tsawg dua cov khoom siv ua nws kom tau zoo dua rau cov kev siv uas muaj zog tsis tseem ceeb.

 

• Cov Kev Tsim Nyog Zoo: Tsim nyog rau cov ntawv thov yuav tsum tau ua thiab khoov cov txheej txheem vim nws qhov kev du dua.

Stkr490:

• Siab Zog: Cov txiaj ntsig ntau dua thiab lub zog tensile ua rau nws haum rau cov ntawv thov uas yuav tsum muaj kev thauj khoom muaj peev xwm.
• Zoo Weldability: Txawm hais tias nws muaj zog dua, Stkr490 tswj tau zoo weldability, ua rau nws tsim nyog rau cov txheej txheem nyuaj thiab cov ntawv thov yuav tsum muaj vuam dav dav.
• Versatility: Ntau yam ntawm cov ntawv thov hauv kev tsim kho, tshuab, kev thauj mus los, thiab marine tshuab vim nws lub zog siab thiab cov kws kho zoo.

Stkr400:

• Kev Siv Dav: Tsim nyog rau cov ntawv thov uas muaj zog thiab cov qauv kev ua haujlwm zoo, xws li lub luag haujlwm zoo thiab cov qauv yooj yim qauv thiab cov qauv yooj yim.
• Lub tsev thiab pej xeem engineering: Siv hauv cov qauv tsis yog cov txheej txheem tseem ceeb xws li scaffolding, thiab kev siv kev siv khoom lag luam.

Stkr490:

• Cov Kev Siv High-Dag Zog: Qhov zoo tagnrho rau cov ntawv thov uas xav tau lub zog muaj zog thiab ua kom muaj zog, muaj cov cuab yeej siv hnyav, thiab cov txuas hniav.
• Neeg kho tshuab thiab tsheb thauj mus los: Siv rau hauv kev tsim cov khoom siv ntawm cov neeg siv tshuab, cov cuab yeej thauj mus los, thiab cov txheej txheem sib xyaw uas muaj zog thiab zoo weldability yog qhov tseem ceeb.

Stkr400yog cov qauv tsim nyog rau cov qauv txheej txheem dav dav uas muaj zog me me thiab muaj kev muaj txiaj ntsig zoo.

Stkr490Yog qhov zoo rau cov kev siv zog high-zog uas xav tau cov xeeb ceem ntau dua thiab cov kev tsim kho zoo, xws li kev tsim kho hnyav thiab kev lag luam hnyav.

Ob chav kawm tau siv dav hauv kev tsim kho thiab tsim khoom lag luam, nrog STKR490 muaj lub zog siab dua thiab cov versatility rau cov ntawv thov ntau dua.
