Q390B yog lub siab -lub zog qis- alloy (HSLA) cov qauv hlau ua raws li tus qauv GB/T 1591, dav siv hauv engineering machinery, tsim qauv, txuas hniav, tsheb, nkoj siab, thiab kav dej engineering. Piv nrog rau cov pa roj carbon monoxide ib txwm muaj, nws muab cov cuab yeej kho kom zoo dua qub, nrog rau cov khoom muaj zog dua, zoo dua toughness, thiab ntau dua cov qauv kev ruaj ntseg. Nws kuj pom zoo weldability, formability, thiab nruab nrab tsis kam rau atmospheric corrosion, ua rau nws ua tau ntseeg tau nyob rau hauv ntev -lub sij hawm sab nraum zoov thiab industrial puag ncig. Nrog nws cov kev ua tau zoo tshaj plaws - rau- tus nqi piv, Q390B steel tau dav lees paub tias yog cov khoom siv zoo tshaj plaws rau kev ua haujlwm hnyav, siab-load, thiab kev nyab xeeb{13}} cov ntaub ntawv tseem ceeb.

Zoo sib xws Standards thiab Steel Qib
Q390B yog piv rau ntau cov qauv thoob ntiaj teb thiab qib steel, uas suav nrog:
ASTM A572 Qib 50: Ib qho zoo sib xws HSLA steel siv hauv cov qauv siv.
TS EN 10025 S355: Tus qauv European rau cov qauv hlau nrog cov khoom siv zoo sib xws.
JIS G3106 SM490: Ib tus qauv Japanese rau dov hlau rau cov qauv welded.
Daim ntawv thov
Q390B alloy steel feem ntau yog siv rau hauv pipeline engineering vim nws lub zog thiab kav ntev. Qee cov ntawv thov siv xws li:
Roj thiab Roj Pipelines: Siv rau kev thauj cov roj thiab roj vim nws lub zog siab thiab corrosion kuj.
Cov Txheej Txheem Txheej Txheem: Ua haujlwm hauv kev tsim cov choj, cov tsev, thiab lwm yam kev tsim kho vaj tse.
Heavy Machinery: Siv rau hauv kev tsim cov khoom hnyav- cov tshuab ua haujlwm thiab cov khoom siv.
Marine Structures: Haum rau siv nyob rau hauv marine ib puag ncig vim nws tsis kam mus rau atmospheric corrosion.
GNEE Steel muab siab -lub zog qis- alloy Q355B steel phaj nyob rau hauv ntau yam specifications, nrog rau cov qauv loj thiab customized qhov ntev, kom tau raws li qhov xav tau ntawm txawv structural engineering, machinery manufacturing, tsim, thiab industrial tej yaam num. Ntxiv nrog rau peb cov khoom siv tag nrho - steel phaj, peb kuj muab cov kev pabcuam customized ua haujlwm xws li txiav, vuam, dabtsi yog khoov, drilling, thiab kho qhov chaw, kom ntseeg tau tias peb cov khoom thiab cov kev pabcuam ua tau raws li koj qhov kev xav tau ntau yam.
