S890 qwyog tus qauv European (EN 10025-6) siab- lub zog ntawm cov qauv hlau, paub txog nws qhov tshwj xeeb yield zog (890 MPa), ua tiav los ntawm quenching thiab tempering ('Q'), thiab zoo kub tsis tshua muaj cuam tshuam toughness ('L' qhia txog kev sim ntawm -40 degree). Nws yog siv rau hauv cov ntawv thov xws li cranes, txuas hniav, thiab kev thauj mus los hnyav, muab lub zog thiab kav ntev thaum seem weldable thiab formable, tso cai rau sib dua, muaj zog tsim.
Cov yam ntxwv tseem ceeb
S: Steel Qauv
890: Yam tsawg kawg nkaus lub zog ntawm 890 Megapascals (MPa)
Q: Quenched thiab Tempered (ib txheej txheem kev kho cua sov)
L: Tsawg kub cuam tshuam toughness (kuaj ntawm -40 degree)
Khoom & Daim Ntawv Thov
Siab zog: Ntau tshaj peb zaug muaj zog dua li cov qauv steel, zoo tagnrho rau kev thauj khoom -cov kabmob.
Weldability zoo: Txawm tias nws lub zog, nws kuj yooj yim rau vuam thiab fabricate.
Durable: Ua tau zoo nyob rau hauv cov xwm txheej hnyav vim nws qhov qis - qhov kub thiab txias tsis kam.
Daim ntawv thov: cranes, mobile platforms, txuas hniav, tsheb thauj mus los hnyav, nqa khoom, thiab cov thawv tshwj xeeb.

Yog xav paub ntxiv nyob rau hauv EN10025-6 S890QL quenched thiab tempered steel phaj daim ntawv pov thawj zoo los yog nug nyob rau hauv kev sib tw official hais, thov hu rau peb.
1. S890QL steel yog dab tsi?
S890QL yog qhov siab heev - lub zog quenched thiab tempered structural steel nrog qhov tsawg kawg nkaus yield zog ntawm 890 MPa, tsim los tuav zoo toughness ntawm qis kub mus rau -40℃.
2. Cov ntawv thov tseem ceeb ntawm S890QL yog dab tsi?
Nws yog siv nyob rau hauv ultra-hnyav mobile crane booms, advanced mining laum rigs, tub rog tsheb thav ntawv, thiab tshwj xeeb offshore Cheebtsam uas siab tshaj plaws lub zog - rau - luj piv yog ib qho tseem ceeb nyob rau hauv cov huab cua txias.
3. S890QL txawv ntawm S690QL li cas?
S890QL muaj zog yield zog (890 MPa vs . 690 MPa) tab sis qis toughness thiab weldability, ua rau nws haum rau hnyav dua - tseem ceeb heev tsis tau xav tau ntau daim ntawv thov.
4. Cov tshuaj muaj pes tsawg leeg ntawm S890QL yog dab tsi?
Nws muaj cov pa roj carbon tsawg, manganese, silicon, thiab micro- alloys xws li niobium, vanadium, thiab boron, nrog rau npib tsib xee, chromium, thiab molybdenum rau hardenability thiab toughness.
5. S890QL puas tuaj yeem welded yooj yim?
Tsis yog, vuam S890QL yog qhov nyuaj thiab yuav tsum muaj cov txheej txheem nruj: qis- cov khoom siv hydrogen, preheating (feem ntau 150-}200 degree), tswj cov cua sov, thiab feem ntau tom qab vuam cua sov kho.
6. Cov qauv twg siv rau S890QL steel?
Nws feem ntau yog tswj hwm los ntawm European tus qauv EN 10025-6 rau quenched thiab tempered high-strength qauv steels.
7. Puas yog S890QL corrosion resistant?
Tsis yog, S890QL tsis yog corrosion{1}}tiv taus thiab yuav tsum muaj cov txheej txheem tiv thaiv xws li pleev xim, galvanizing, los yog tshwj xeeb plating rau siv nyob rau hauv corrosive ib puag ncig.
8. Yuav ua li cas tshuab S890QL steel?
Machining S890QL yog qhov nyuaj vim nws qhov siab hardness; nws yuav tsum tau siv cov cuab yeej carbide muaj zog, kev txiav qeeb qeeb, siab - siab txias txias, thiab kev teeb tsa nruj.
9. Tus nqi ntawm S890QL steel phaj yog dab tsi?
S890QL tseem kim dua li qis dua -qib steels, nrog cov nqi sib txawv raws li tuab, ntau, thiab ntawv pov thawj, feem ntau yog li ntawm € 2,500 txog €4,500+ ib tuj.
