EN10025 European Standard Cov Qauv Hlau
EN 10025 yog European tus qauv qauv hlau rau cov khoom kub dov hauv carbon steel. S355 qib kuj tau txhais nyob rau hauv tus qauv no, tsis yog qib no kuj muaj S235, S275, S460, S550, S620, S690 nrog rau tej yam kev mob kub dov, normalized, quenched, thiab tempered.
S355 Qib ntau S355JR, S355J0, S355J2, S355K2 uas yog cov khoom siv hlau tsis-alloy tau teev tseg hauv EN 10025 tus qauv.
"S" txhais tau tias cov qauv, "355" sawv cev rau lub zog tawm los ntawm 355 Mpa yam tsawg kawg nkaus. JR tau hais tias cov hlau yuav tsum tau kuaj qhov cuam tshuam ntawm 27 Joules nrog logitudinal Charpy V-Notch cuam tshuam rau hauv chav tsev kub. Uas muaj ntau qhov kev xaiv ntawm charpy xeem suav nrog J2, J0, thiab K2.
S355JR qib steel yog cov khoom tseem ceeb siv hauv kev tsim vaj tsev. Nws muab cov txiaj ntsig zoo tshaj plaws thiab lub zog tensile ib txwm muab nrog ntau yam kev kho mob thiab kev sim, kom paub tseeb tias nws yog qhov kev xaiv zoo los siv hauv kev lag luam thiab cov haujlwm sib txawv.
