S890Q steel yog dab tsi thiab nws lub npe txhais li cas?
S890Q yog ib qho siab -lub zog quenched thiab tempered structural steel tau teev nyob rau hauv European qauv (xws li EN 10025-6). Lub "S" sawv cev rau cov qauv hlau, "890" qhia qhov tsawg kawg nkaus lub zog ntawm MPa, thiab "Q" txhais tau tias quenched thiab tempered (QT) kev kho cua sov.
Dab tsi yog cov khoom siv kho tshuab ntawm S890Q?
S890Q feem ntau muaj qhov tsawg kawg nkaus lub zog ntawm 890 MPa, qhov tsawg kawg nkaus tensile zog feem ntau nyob rau hauv thaj tsam 960-1100 MPa, zoo toughness (feem ntau teev nrog Charpy V-notch qhov tseem ceeb ntawm qhov kub thiab txias), thiab weldability zoo thaum ua raws li cov txheej txheem.
Dab tsi yog cov ntawv thov ntawm S890Q steel?
S890Q yog siv nyob rau hauv hnyav- cov qauv ua haujlwm uas muaj lub zog siab thiab qhov hnyav txo yog qhov tseem ceeb, xws li crane booms, mobile crane qauv, siab - nce lub tsev Cheebtsam, offshore qauv, thiab cov khoom hnyav.
Kev kho cua sov dab tsi yog siv rau S890Q?
S890Q yog tsim los ntawm quenching (ceev txias) ua raws li los ntawm tempering (reheating mus rau ib tug qis kub thiab txias), uas ua tiav lub zog siab thaum tuav lub toughness thiab txo brittleness.
Qhov kev txiav txim siab vuam dab tsi tseem ceeb rau S890Q?
Cov kev txiav txim siab tseem ceeb ntawm vuam muaj xws li preheating thiab interpass kub tswj los tiv thaiv hydrogen-vim tawg, siv tsawg- hydrogen vuam consumables, tswj cov cua sov input, thiab ua post-weld heat treatment (PWHT) thaum xav tau los ntawm kev tsim los yog code.
S890Q piv rau S690Q li cas ntawm lub zog thiab daim ntawv thov?
S890Q muaj lub zog qis dua qhov qis dua (890 MPa vs . 690 MPa rau S690Q). Qhov no tso cai rau S890Q kom ua tiav tib lub thauj khoom- nqa lub peev xwm nrog cov ntu nyias, ua rau nws nyiam qhov hnyav dua -sensitive lossis siab dua- cov ntawv thov xws li crane loj booms, whereas S690Q yog siv nyob rau hauv ntau qhov dav ntawm cov qauv hnyav uas tsis muaj zog heev.
S890Q piv li cas rau quenched-thiab-tempered carbon-manganese steels (xws li, A514/A517 hauv ASTM) raws li tus qauv thiab cov khoom?
S890Q yog tus qauv European (EN) siab- lub zog cov qauv hlau nrog cov lus qhia tawm lub zog thiab cov kev xav tau nruj, feem ntau nrog kev tswj nruj dua ntawm kev siv tshuaj thiab kev kho cua sov rau kev siv cov qauv. ASTM A514/A517 kuj yog QT siab -lub zog steels tab sis ua raws li Asmeskas cov qauv; lawv qhov kev xaiv qib, qib siab, thiab qhov yuav tsum tau ua kom nruj / ntsuas yuav txawv. Ob qho tib si yog siv rau kev siv cov qauv hnyav, tab sis kev pom zoo ntawm cov khoom siv thiab cov khoom siv tshwj xeeb yog nyob ntawm qhov project tus qauv qauv (EN vs. ASTM).
S890Q piv rau kub - dov siab - lub zog steels (xws li S355) li cas ntawm lub zog, toughness, thiab fabrication?
S890Q muaj zog tawm los ntau dua S355 (890 MPa vs . 355 MPa), ua kom qhov hnyav txo. Nws kuj feem ntau muab cov tawv tawv zoo dua ntawm qhov kub qis dua vim QT kev kho cua sov. Txawm li cas los xij, S890Q yuav tsum tau ceev faj ntau dua: cov txheej txheem vuam nruj dua (preheat, qis- cov khoom siv hydrogen), tswj kev txiav ntau dua thiab tsim kom tsis txhob tawg, thiab feem ntau cov ncauj lus kom ntxaws txog kev tswj hwm zoo dua piv rau kev zam txim ntau dua ntawm S355.
