↵S890Q, S890QL, thiab S890QL1 yog siab- lub zog steels (EN 10025-6 tus qauv) nrog rau qhov tsawg kawg nkaus tawm lub zog ntawm 890 MPa, sib txawv los ntawm lawv qhov yuav tsum tau muaj kev cuam tshuam toughness ntawm cov kub qis dua:S890Q(hauv paus -20 degree),S890 qw(zoo dua -40 degree), thiabS890QL 1(superior -60 degree), ua rau lawv haum rau cov huab cua txias, tag nrho cov tiav los ntawm quenching thiab tempering (Q).
Common nta muaj xws li:
- Yam tsawg kawg yield zog ntawm890 MPa ua
- Siab tensile zog thiab zoo heev load kuj
- quenched thiab tempered khoom xa tuaj
- Tsim los rau kev thov cov qauv siv
Qhov sib txawv tseem ceeb nyob hauvcuam tshuam kev ntsuas kub thiab toughness yuav tsum tau.
Mechanical Properties Sib piv
1. S890Q steel phaj
Impact test kub:-20 degree
Hom kev siv:Txheem siab -lub zog siv cov qauv
Qhov zoo:Tus nqi -zoo, siv dav, qhov sib npaug zoo ntawm lub zog thiab tawv
S890Q yog tsim rau cov tshuab hnyav, cranes, thiab cov qauv ua haujlwm hauv qhov chaw ib puag ncig lossis qis qis.
2. S890QL steel phaj
Impact test kub:-40 degree
Hom kev siv:Cov qauv hauv cov huab cua txias dua lossis muaj kev nyab xeeb dua-xav tau tej yaam num
Qhov zoo:Txhim kho qis -kub toughness thiab tawg kuj
S890QL muab cov npoo kev nyab xeeb siab dua li S890Q, ua rau nws zoo tagnrho rau cov chaw sab nrauv, cov qauv cua, thiab txias - cheeb tsam kev tsim kho.
3. S890QL1 Hlau Phaj
Impact test kub:-60 degree
Hom kev siv:Cov huab cua txias heev
Qhov zoo:Superior toughness nyob rau hauv tsis tshua muaj kub
S890QL1 yog siv nyob rau hauv Arctic, sub-zero, los yog xav tau ib puag ncig uas muaj kev ncaj ncees ntawm qhov kub thiab txias yog qhov tseem ceeb heev.
Toughness: Tus Txheej Txheem Tseem Ceeb (Q vs QL vs QL1)
Thawj qhov txawv yog nyob rau hauvlow -kub toughness-ib qho tseem ceeb rau cov ntawv thov hauv huab cua txias lossis ib puag ncig hnyav.
Cov lus kawg "Q", "QL", thiab "QL1" qhia txog qhov yuav tsum tau ua kom muaj zog, ntsuas los ntawm Charpy V- qhov ntsuas qhov cuam tshuam:

GNEE Steel's S890QL thiab S890QL1 siv cov txheej txheem steel ua kom zoo (piv txwv li, ladle refining, nqus degassing) kom txo cov impurities, txhim kho toughness yam tsis muaj kev cuam tshuam lub zog. Qhov no ua rau peb cov phiaj xwm zoo rau cov haujlwm hauv hnyav, qis- qhov kub thiab txias.
Qib sib npaug: Cov Qauv Thoob Ntiaj Teb Hla-Reference
Rau cov haujlwm thoob ntiaj teb, kev nkag siab cov qib sib npaug yog qhov tseem ceeb. Hauv qab no yog cov ntaub ntawv ceev ceev rau S890Q, S890QL, thiab S890QL1 hla cov qauv loj- txheeb xyuas los ntawm GNEE Steel pab pawg kws tshaj lij:
ASTM (USA): Tag nrho peb qib yog sib npaug rau A514 Qib Q (quenched & tempered, Ntau tshaj lossis sib npaug rau 890 MPa yield zog).
JIS (Nyiv): Ua raws li SSAB Domex 100Q/QL/QL1 lossis JFE-HITEN 1000Q/QL.
GB (Tuam Tshoj): S890Q ≈ Q960C; S890QL ≈ Q960D; S890QL1 ≈ Q960E (ib GB / T 16270).
EN (Tebchaws Europe)Kev them nyiaj ncaj qha los ntawm EN 10025-6, nrog QL / QL1 raws li kev hloov kho toughness variants ntawm Q.
Yuav Ua Li Cas Xaiv Cov Qib Zoo?
- XaivS890Qrau cov qauv siab -lub zog cov qauv siv
- XaivS890 qwrau cov huab cua txias los yog muaj kev nyab xeeb ntau dua
- XaivS890QL 1rau qhov tsis tshua muaj - qhov kub thiab txias
