SRUBIJA JEZIK (LATINICA)Taw qhia ntawm lub zog siab q&T steel phaj
Lub siab muaj zog tempered steel phaj yog ib hom qauv steel phaj uas tau raug quenched thiab tempered kom ua tiav lub zog siab thiab kev ua tau zoo tag nrho. Cov khoom siv kho tshuab thiab kev ua haujlwm ntawm cov hlau tau txhim kho los ntawm cua sov thiab txias rau cov phaj steel. Tempered steel phaj tuaj yeem tiv taus qhov hnyav thiab hnav. Lub ntsiab high-strength structural steel daim hlau yog raws li nram no.
Q460 high-strength steel phaj
Qib steel los ntawm thawj tsab ntawv ntawm Hanyu Pinyin sawv cev ntawm lub zog tawm los, qhov tsawg kawg nkaus yield zog tus nqi, qib zoo ntawm peb qhov sib lawv liag.
Q: Thawj tsab ntawv ntawm Suav spelling ntawm "Qu", kuj txhais tau tias muaj zog yield.
460: Qhov tsawg kawg nkaus tawm lub zog yog 460 MPa ( steel txoj kab uas hla Tsawg dua los yog sib npaug li 16 hli)
C / D / E / F: Qib zoo ntawm cov hlau.

Daim Ntawv Thov Ntawm Lub Zog Q&t Hlau Phaj
1. Kev tsim kho
High-strength quenched thiab tempered steel daim hlau yog siv los tsim cov hlau loj loj. Lawv kuj muab kev txhawb nqa ruaj khov thiab muaj peev xwm hnyav rau cov tsev siab siab.
2.Mechanical teb
Qee cov khoom siv tau raug kev ntxhov siab thiab kev poob siab thaum ua haujlwm. Nrog kev ua tau zoo ntawm lub zog siab thiab tawv, hom steel phaj no tuaj yeem tiv taus qhov hnyav ua haujlwm.
3.Shipbuilding thiab marine steel platform
Quenched thiab tempered steel daim hlau yog siv nyob rau hauv shipbuilding thiab offshore steel platforms vim lawv muaj anti-corrosion kuj.
4. Cov choj
High-strength structural steel daim hlau yog zoo tagnrho rau tsim lub ntsiab girders thiab kev txhawb nqa rau choj.
