S960QL yog quenched thiab tempered (quenched + tempered) siab -lub zog steel ua raws li European tus qauv EN 10025-6. Nws yog lub npe hu rau nws lub zog muaj zog heev thiab zoo heev tsawg- kub toughness, thiab feem ntau yog siv nyob rau hauv cov teb uas tsis tshua muaj siab yuav tsum tau rau load-bearing muaj peev xwm thiab hnyav txo, xws li cranes, mining machinery, thiab hnyav thauj.
EN S960QL steel tso cai rau cov tuam txhab tsim khoom kom txuag tau qhov hnyav hauv qhov lawv tab tom tsim.

Ob qho Q960 thiab S960QL yog 960MPa qib siab- lub zog cov qauv steel, sib txawv hauv lawv cov qauv siv, qis- kub cuam tshuam toughness, thiab daim ntawv thov scenarios. S960QL (Tebchaws Europe tus qauv) muaj kev nruj dua - qhov yuav tsum tau muaj qhov kub thiab txias ({10}}50 degree) thiab kev ruaj ntseg zoo dua, haum rau qhov chaw txias heev; Q960 feem ntau yog hais txog Suav lub teb chaws tus qauv siab-lub zog steel, hais txog lub zog siab tawm los.
Paub meej qhov sib txawv:
Cov ntsiab lus thiab cov qauv:
* S960QL: Ua raws li European tus qauv EN10025-6. Qhov twg S qhia txog cov qauv hlau, 960 qhia tias lub zog tawm los> 960MPa, Q sawv cev rau quenched thiab tempered, thiab L sawv cev rau qhov kub thiab txias.
* Q960: Feem ntau yog hais txog siab - lub zog steel raws li cov qauv hauv Suav teb (xws li GB / T16270 lossis cov qauv kev lag luam zoo sib xws), hais txog lub zog tawm ntawm 960MPa.
Tsawg-Temperature Impact Toughness (Key Difference):
* S960QL: cog lus zoo cuam tshuam ntawm -50 degree.
Q960: Tsawg-kub toughness feem ntau qis dua me ntsis, lossis cuam tshuam kev ua haujlwm ntawm qhov kub thiab txias tsis tau teev tseg (nyob ntawm tus qauv tshwj xeeb).
Daim ntawv thov:
S960QL: Feem ntau siv nyob rau hauv crane booms, siv machinery nyob rau hauv frigid regions, loj siab hlab ntsha, thiab lwm yam khoom uas muaj kev ntseeg siab thiab txias brittleness yog qhov tseem ceeb.
Q960: Tsim nyog rau siab -lub zog load-cov kabmob cov qauv uas yuav tsum tau ua kom txias brittleness tsawg dua.
Cov tsiaj ntawv thiab cov lej hauv S960QL txhais li cas?
S: Cov qauv hlau
960: Yield zog Ntau dua los yog sib npaug rau 960 MPa
Q: Quenched thiab Tempered
L: Guaranteed qis- kub cuam tshuam toughness ntawm -40 degree
S960QL puas tuaj yeem welded? Dab tsi yuav tsum tau sau tseg thaum vuam?
S960QL muaj qhov zoo weldability thiab tuaj yeem ua tiav los ntawm cov txheej txheem vuam xws li arc vuam thiab roj hlau arc vuam.
