Loj -Ntau qhov chaw: Siv rau hauv lub ru tsev trusses thiab framing rau cov chaw ua si kis las, chaw ua yeeb yam, thiab tshav dav hlau los txhawb kev ncua ntev yam tsis muaj kev sib tw sab hauv.
Seismic Structures: Nws lub zog siab thiab ductility yog siv hauv av qeeg -cov qauv tiv thaiv kom nqus seismic rog.
2. Heavy Machinery & Khoom siv
Cov khoom siv ruaj khov thiab muaj peev xwm thauj khoom siab ua rau nws tseem ceeb rau "cov khoom daj" thiab cov tshuab ua haujlwm:
Lifting Equipment: Qhov tseem ceeb rau crane booms, dipper sticks, thiab hnyav- lub luag haujlwm nqa cov qauv.
Mining & Earthmoving: Siv nyob rau hauv excavator thoob, bulldozers, thiab mining machinery los tiv thaiv huab cua thiab loads siab.
Forestry: Ua hauj lwm hauv hav zoov harvesters uas tsis tshua muaj qauv tsim nyog rau kev mus los nyob rau hauv hnyav struts.
3. Tsheb thauj mus los & Tsheb
S960Q pab txhawb kev txhim kho cov tsheb thauj mus los yooj yim kom txo tau roj noj thiab emissions:
Lub Tsheb Hnyav: Kev tsim cov tsheb thauj khoom, cov tsheb thauj khoom, thiab cov kab tsheb ciav hlau rau hnyav- lub luag haujlwm thiab lub teeb ua lag luam tsheb.
Railway: Siv rau cov khoom siv tsheb ciav hlau thiab cov neeg caij tsheb cov qauv lub cev.
Tshwj xeeb Logistics: Muaj feem xyuam rau intermodal shipping thawv thiab bulk thauj khoom.
4. Zog & Marine
Offshore Engineering: Siv nyob rau hauv cov roj rigs, offshore platforms, thiab shipbuilding qhov twg ob lub zog thiab toughness yuav tsum tau tiv thaiv hnyav hiav txwv tej yam kev mob.
Cov Khoom Siv Hluav Taws Xob: Siv rau hauv kev tsim cov hlab ntsha uas tsis muaj hluav taws xob, cov ntaub ntawv turbine scroll, thiab penstocks.
Sustainable Energy: Kev siv tshiab hauv kev txhawb nqa rau kev tsim vaj tsev ntsuab thiab tom ntej -tsim fais fab nroj tsuag.
Variants
S960Q belongs rau tsev neeg ntawm cov qib sib txawv los ntawm lawv qhov qis -kub toughness:

Dab tsi yog qhov txawv ntawm S960Q thiab S960QL?
S960QL yog qib qis -kub ntawm S960Q. Ob leeg muaj 960 MPa yield zog, tab sis S960QL muaj zoo toughness ntawm qis kub (-40℃vs . -20℃rau S960Q).
Yuav ua li cas txiav S960Q?
S960Q tuaj yeem txiav los ntawm nplaim taws, txiav ntshav, lossis laser txiav. Nplaim txiav yuav tsum tau preheating kom tsis txhob tawg. Laser thiab plasma txiav yog ntau meej rau nyias mus rau nruab nrab thicknesses.
Qhov siab tshaj plaws thickness ntawm S960Q yog dab tsi?
Qhov siab tshaj plaws muaj thickness ntawm S960Q feem ntau yog mus txog 150 hli. Cov phaj tuab dua tuaj yeem xav tau kev kho cua sov kho kom ntseeg tau tias cov khoom siv kho tshuab tsis sib xws thoob plaws -section.
Puas yog S960Q corrosion-resistant?
S960Q muaj qhov yooj yim corrosion kuj, zoo ib yam li carbon hlau. Rau ib puag ncig hnyav (marine, tshuaj lom neeg), nws xav tau kev tiv thaiv xws li pleev xim, galvanizing, lossis corrosion- cov coatings resistant.
Dab tsi yog qhov cuam tshuam lub zog ntawm S960Q?
Ntawm -20 degree, S960Q qhov cuam tshuam tsawg kawg nkaus lub zog (Charpy V-notch) yog 30 J. Qhov no ua kom nws tuaj yeem nqus tau lub zog tsis muaj pob txha tawg nyob rau hauv qhov kev cuam tshuam tam sim ntawd hauv kev ua haujlwm ib txwm muaj.
S960Q puas tuaj yeem khoov?
Yog lawm, S960Q tuaj yeem khoov tau, tab sis nrog kev tswj lub vojvoog nruj. Qhov tsawg kawg nkaus khoov vojvoog feem ntau yog 3-5 npaug ntawm cov phaj tuab. Preheating tej zaum yuav xav tau rau cov phaj tuab kom tsis txhob tawg thaum khoov.
Dab tsi welding consumables yog siv rau S960Q?
Vuam consumables rau S960Q yuav tsum phim nws lub zog. Tsawg-hydrogen electrodes (E11018-G), flux-cov xov hlau (E110T5-K3), lossis cov xaim hlau (ER110S-G) feem ntau yog siv los xyuas kom muaj kev sib koom ua ke ntawm lub zog thiab lub zog.
Dab tsi yog qhov ceev ntawm S960Q?
Qhov ceev ntawm S960Q yog kwv yees li 7.85 g / cm³, tib yam li cov pa roj carbon ntau thiab tsawg- alloy steels. Qhov ntom ntom no yog siv rau kev ntsuas qhov hnyav hauv kev tsim qauv thiab kev tsim khoom.
S960Q puas tuaj yeem siv rau hauv cov qauv sab nrauv?
Yog lawm, S960Q yog tsim rau offshore qauv zoo li roj platforms. Nws lub zog siab thiab qis -kub toughness tiv taus cov dej hiav txwv hnyav, tab sis kev tiv thaiv corrosion yog tsim nyog.
Dab tsi yog qhov elongation ntawm kev tawg ntawm S960Q?
