I. Cov nomenclature thiab Cov Qauv
Lub ntsiab lus ntawm qib:
- "Q": Pelig zog (thawj tus tsiaj ntawv ntawm Suav Pinyin rau cov txiaj ntsig lub zog).
- "460": Yam tsawg kawg nkaus qis zog zog lub zog ntawm 460 MPA.
- "DR": Cov cim tshwj xeeb rau tsawg - kub cov hlab ntsha.
Cov Qauv Txheej Txheem:
- Lub Tebchaws Txuj Ci: GB / T 713.3-2023 (siv nyob rau lub Peb Hlis 2024).
- Sib sau cov txheej European: EN 10028-3: 2017 P460NL1.

| Leej mos | S | Tsawg dua los yog sib npaug rau 0.008% |
III. Cov Khoom Siv Neeg Kho Tshuab
- Tos Lub Zog: 460 MPa
- Lub zog tensile: 630 ~ 730 MPa (cuam tshuam los ntawm cov tuab)
- Elongation: ntau dua los yog sib npaug rau 18% (rau thickness 6 ~ 20mm)
- Tsawg - kub kev ua tau zoo: kev nqus hluav taws xob ntawm {}}} kev kawm ntau dua los yog sib luag rau 60 J, kom ua kom muaj kev kub ntxhov qis.
IV. Daim Ntawv Thov
Mas siv nyob rau hauv kev tsim cov khoom lag luam qis - qhov chaw nres tsheb siab, uas yuav tsum tau walland siab {{1}-}} qhov chaw dej sov.
V. Kev Xa Khoom thiab Kev Soj Ntsuam
Kev Kho Cua Sov:Li qub lossis normalizing + tempering (Ultrasonic kev kuaj mob thaum tuab ntau dua lossis sib npaug rau 6 hli).
Tsis - Kev Kuaj No: Txhua daim ntawv pov tseg ultrasonic kev sim thaum tuab ntau dua lossis sib npaug rau 6 hli.
VI. Cov yam ntxwv ua tau zoo
Siab zog thiab tsawg - kub ceev:Sib tw thauj khoom - Cov kabmob muaj peev xwm thiab qis- kev cuam tshuam kub.
Weldability:Ruaj ruaj welded pob qij txha, ntsib cov cai ntawm cov txheej txheem nyuaj.
Ntsiab lus:Los ntawm kev kho cov tshuaj lom neeg tshuaj lom neeg thiab cov txheej txheem kho cua sov, Q460DR Cov Khoom Siv Cua Sov nrog cov khoom siv nruj me me thiab kub}
