P500QL1 thiab P500QL2 yog siab- lub zog, weldable zoo- cov hlau phaj tau teev tseg raws li EN 10028-6 tus qauv, feem ntau yog siv rau cov hlab ntsha siab thiab boilers, sib txawv feem ntau hauv lawv qhov ntsuas kub tsis tshua muaj kev cuam tshuam cov kev xav tau: P500QL10, P500QL10 (qhov yuav tsum tau muaj qhov ntsuas ntawm L0) thaum nws yuav tsum tau ntsuas qhov ntsuas ntawm L ntau txias dua -60℃(L2), ua rau nws tsim nyog rau kev khiav hauj lwm kub, ob qho tib si nkag rau hauv ib tug quenched thiab tempered (Q + T) mob rau kev txhim kho kev ua tau zoo.
Kev Siv Tshuab Ntxiv: HIC Test|NACE MR0175|Z15|Z25|Z35 |
Thickness: 6mm-300mm,
Dav: 1500mm txog 4050mm,
Ntev: 3000mm txog 15000mm
Cov yam ntxwv tseem ceeb
Txheem: EN 10028-6 (Weldable fine grain steels for pressure purposes, quenched and tempered).
Daim ntawv thov: High- cov khoom siv kub, boilers, thiab cov hlab ntsha siab.
Kev Xa Khoom: Quenched thiab Tempered (Q + T).
Lub zog: P500 qhia qhov tsawg kawg nkaus lub zog ntawm 500 MPa (rau tej thicknesses).
Qhov "QL1" vs "QL2" Qhov txawv
Q: Qhia txog quenched & Tempered (Q + T).
L1: Qhia qhov qis- qhov ntsuas kub ntawm qhov ntsuas kub ntawm -40 degree, yuav tsum muaj qhov cuam tshuam tsawg kawg nkaus ntawm 27 Joules (J).
L2: Qhia qhov qis qis qis dua - qhov ntsuas kub ntawm qhov ntsuas qhov ntsuas tau ua tiav ntawm -60 degree, kuj yuav tsum tau 27J, ua rau qhov chaw txias dua.
