"QL1" txhais li cas hauv S690QL1?
Cov "QL1" nyob rau hauv qib steel S690QL1 yog sub-qib npe teev tseg los ntawm European tus qauv EN 10025-6. Nws qhia txog qhov yuav tsum tau muaj kev cuam tshuam toughness (chav kawm toughness) ntawm qhov kub thiab txias.
Nov yog qhov kev sib cais:
Q:Stands rau "Quenched thiab Tempered" - txheej txheem kev kho cua sov uas muab cov hlau nws lub zog siab thiab toughness.
L:Stands rau "Tsuas Kub" kev pab cuam, lub ntsiab lus cov hlau yog guaranteed kom muaj toughness nyob rau hauv freezing tej yam kev mob.
1:Tus naj npawb "1" qhia txog qhov kub thiab txias yam tsawg kawg nkaus uas yuav tsum tau muaj zog rau Charpy V-qhov ntsuas ntsuas. Rau S690QL1, qhov no txhais tau tias:
Kev ntsuas kub: -60 ° F (-76 ° F)
Yam tsawg kawg nkaus zog: Ntau dua lossis sib npaug li 40 Joules(qhov nruab nrab ntawm 3 qhov kev xeem)
Hauv cov ntsiab lus:
S690 qw 1yog quenched thiab tempered steel nrog 690 MPa yield zog, tshwj xeeb certified kom xa tsawg kawg yog 40 Joules ntawm lub zog cuam tshuam ntawm -60℃. Qhov no ua rau nws tsim nyog rau cov kev siv hauv cheeb tsam txias tshaj plaws, xws li Arctic offshore cov qauv, cov khoom tseem ceeb hauv kev tshawb nrhiav lub ncov qaumteb qabteb, lossis cov tshuab tshwj xeeb ua haujlwm hauv qhov txias txias qhov twg tsis ua haujlwm yog qhov kev xaiv.
Kev sib piv nrog rau lwm cov qib sub-:
S690Q:Feem ntau kuaj ntawm 0 degree.
S690 QL:Kuaj ntawm -40℃nrog qhov yuav tsum tau muaj ntau dua lossis sib npaug rau 27 J.
S690 QL1:Kuaj ntawm -60℃nrog qhov yuav tsum tau muaj ntau dua lossis sib npaug rau 40 J (siab dua toughness ntawm qhov qis dua).
