** 1. Dab tsi yog en 10025 specification? **
EN 10025 yog European tus qauv qhia cov txheej txheem kev mob cov tswv yim rau kub-rolled qauv txheej txheem steel, suav nrog cov kab teeb ci, kab, thiab kab. Nws npog nws cov uas tsis yog-alloy thiab alloy hlau siv hauv kev tsim kho, txuas hniav, thiab lwm yam kev coj ua-coj. Tus qauv piav qhia txog cov tshuaj muaj pes tsawg leeg, piv txwv li cov khoom siv txhua yam (piv txwv li, tawm los lub zog, tensile lub zog), thiab kev sim cov qauv.
** 2. Dab tsi yog en 10025-2 s355J 2+ n sib npaug rau? **
En 10025-2}}} 2+}}}} Kuv yog sib npaug rau **}}} g310 Tus "+ n" qhia tau li cas los dov. It has a minimum yield strength of 355 MPa, good toughness at low temperatures (-20 degree ), and improved weldability. Kev sib txig sib luag yog nyob ntawm cov txheej txheem hauv cheeb tsam thiab cov cai ua kom tiav.
** 3. Dab tsi yog en 10025-2}}} qib s275jr? **
En 10025-2 s275jr yog cov qauv tsis-alloy txheej txheem nrog tsawg kawg nkaus zog lub zog ntawm 275 MPa. Lub "JR" Suffix qhia tias nws muaj Charpy tsawg kawg V-Motch cuam tshuam lub zog ntawm 27 j ntawm {{6} degree. Nws yog feem ntau siv nyob rau hauv kev tsim kho dav dav, machinery, thiab welded Cheebtsam vim nws qhov chaw zoo, Weldability, thiab tus nqi-ua hauj lwm zoo.
** 4. Dab tsi yog khoom siv en 10025 s355jr? **
En 1 {0} 0}}}}}}}}}}}}}} tus txheej txheem steel nrog li 355 MPa. Lub "J" qhia txog kev cuam tshuam lub zog yuav tsum muaj ntawm 27 J ntawm 0 degree (ntau tawv ( Nws yog dav siv nyob rau hauv cov ntawv thov hnyav-zoo li choj, cranes, thiab vaj tse vaj tse.
** 5. Dab tsi yog cov hlau me me BS EN 10025 S275JR? **
BS EN 10025 S275JR yog tus qauv British-saws ntawm EN 10025 rau cov hlau sib txawv \/ cov hlau. Nws muaj tsawg kawg yog lub zog zog ntawm 275 MPa thiab yog tus cwj pwm los ntawm kev muaj fircability zoo, weldability, thiab lub zog. Lub "JR" ua kom muaj kev cuam tshuam kev cuam tshuam nyuaj ntawm +20 degree. Nws yog feem ntau siv hauv kev tsim kho, thav duab, thiab tsis yog-tseem ceeb load-bearing Cheebtsam.
