Qib S890Q steel sib npaug li cas?
S890Q yog European high -yield zog structural steel (EN 10025-}6) nrog lub zog tsawg kawg nkaus ntawm 890 MPa nyob rau hauv quenched thiab tempered (Q) mob, sib npaug rau qib zoo li Q890 (Tuam Tshoj), thiab zoo ib yam li hauv daim ntawv thov rau ASTM A570 muaj zog zoo li, Weld-du cranes, thiab cov tshuab hnyav, nrog rau kev cuam tshuam tshwj xeeb ntawm -20 degree.
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.
