Qhov txawv ntawmS500QthiabS500 QLyogfeem ntau nyob rau hauv naming convention thiab kev lag luam siv, tsis nyob rau hauv kev specification.Hauv kev xyaum, lawv xa mus rau lubtib yam khoom sivraws li tus qauv official.
Ntawm no yog qhov yooj yim tawg:
Official Standard txhais
Raws liTS EN 10025-6, qhov raug thiab ua tiav yog:
S500 QL
S500 QL1
Tus qauvtsis officially txhaisib qib hu ua xwb"S500Q".
Dab tsi "S500QL" txhais tau tias:
S:Cov qauv tsim
500:500 MPa yam tsawg yield zog
Q:Quenched & Tempered
L:Tsawg kub cuam tshuam toughness
1:Optional sub-qib rau tej thickness/toughness
Vim Li Cas Koj Pom Ob Lub Npe ("S500Q" vs. "S500QL")
Informal Shorthand:Hauv kev lag luam, catalogs, thiab kev sib tham,"S500Q"feem ntau yog siv los ua ib qho yooj yim shorthand rauS500 QL. Nws zoo li hais tias "S500 Quenched steel."
Kev nkag siab ntawm cov ntsiab lus:Thaum tus kws tsim khoom lossis tus kws tsim khoom hais tias "S500Q," txhua tus neeg hauv thaj chaw nkag siab lawv txhais tau tias qib quenched thiab tempered nrog lav qis -kub toughness (tus "L" khoom).
Kev yuav khoom:Rau kev yuav khoom, koj yuav tsum siv lubua tiav lub npe "S500QL"kom tsis txhob muaj qhov tsis meej pem.
Puas Muaj Ib qho Kev Sib Txawv?
Tsis muaj.Yog tias ib lub zeb muab cov khoom siv sau npe "S500Q" ntawm daim ntawv pov thawj, nws yuav tsum ua kom tau raws li tag nrho cov kev xav tau ntawm cov tshuaj lom neeg, khoom siv, thiab toughness.S500 QLRaws li EN 10025-6 kom ua raws.
Tus qauv qhiaYuav tsum muaj kev cuam tshuam toughness kuaj ntawm qhov kub thiab txiasrau tag nrho nws cov qib. Yog li ntawd, qhov "L" (rau qhov kub thiab txias) yog ib feem ntawm qhov "Q" (quenched & tempered) nyob rau hauv tus qauv no. Koj tsis tuaj yeem muaj qib "Q" yam tsis muaj lub zog toughness txhais los ntawm "L."
Tsev Neeg Cov Qib Siab hauv EN 10025-6
Ntawm no yog cov npe nom tswv thiab lawv cov kev cai tseem ceeb toughness:
| Official Qib | Impact Test Temperature | Yam tsawg kawg nkaus zog |
|---|---|---|
| S500 QL | -40 degree | 30 Joules (rau thickness 16-50 mm) |
| S500 QL1 | -60 degree | 30 Joules (rau thickness 16-50 mm) |
Kev Siv Tau Rau Koj:
Yog koj pom"S500Q"nyob rau hauv ib phau ntawv lossis kos duab, koj tuaj yeem ntseeg siab kho nws liS500 QL.
Raudaim ntawv thov tseem ceebNyob rau hauv qhov chaw txias heev (piv txwv li, Arctic offshore), koj yuav tsum tau qhia meej meej txog qib toughness siab duaS500 QL1.
Ib txwmtxheeb xyuas cov ntaub ntawv xeem daim ntawv pov thawj-nws yuav sau tag nrho EN 10025-6 tus qauv thiab cov txiaj ntsig kev sim tiag tiag (nrog rau qhov cuam tshuam qhov ntsuas kub).
Cov ntsiab lus:

S500 QLyog covofficial, npehauv tus qauv.
Lawv xa mus rau tib lub steel:ib qho ultra- siab- lub zog (500 MPa tawm los), quenched thiab tempered structural steel nrog guaranteed toughness ntawm -40℃.
Kab hauv qab: Siv "S500QL" hauv kev qhia tshwj xeeb. Thaum koj hnov "S500Q," nkag siab nws txhais tau tias S500QL.Lub ntsiab lus tseem ceeb xaiv xaiv yog nruab nrabS500 QL(-40 degree) thiabS500 QL1(-60 degree) rau qhov xav tau kev pabcuam kub.
