GB / T 4171 Q550NH STEEL PhajMuaj peev xwm tiv taus ntev -}}}}}}}}}} Lub cev muaj huab cua tsis zoo lossis yog vim li no cov huab cua - Cov hlau tiv taus.
Qhov no steel phaj yog qhov siab - lub zog, qis {{}} almoy qauv siv tshuaj sib xyaw nrogC Tsawg dua los yog sib npaug rau 0.20%, Si 0.25-0.75%, P 0.0-0.50%, thiab ni tsawg dua lossis sib npaug nrog 0.65%, kom ntseeg tau zoo heev corrosion tsis kam rau ntev - sij hawm siv sab nraum zoov.
Nyob rau hauv cov nqe lus ntawm cov neeg kho tshuab, q55050nh steel phaj muaj apaib lub zog ntawm 550 MPA, a tensile lub zog ntawm 650-810 mpa, thiab ibelongation ntawm 18-22%, tswj kom muaj kev ua kom zoo thiab kev ntseeg tau txawm tias muaj tsawg - qhov chaw ib puag ncig.
Cov hlau saum npoo ib txwm ua aNtse oxide txheej kwv yees li 50-100 μm tuab, uas ua rau qeeb qeeb ntxiv corrosion, muab ibKev Pab Lub Neej ntawm 20-30 xyooshauv nroog loj lossis chaw muaj kev lag luam, thiab dhau mus25 xyooNyob rau hauv ntug dej hiav txwv lossis siab - av noo.
Gnee steelmuaj kev paub ntau hauv kev muab khoomGB / T 4171 Q550NH STEEL HLAU, uas tau siv dav hauvchoj, cov tsheb ciav hlau cov tsheb ciav hlau, cov thawv, tsim tsev, thiab sab nraum zoov cov chaw sab nraum zoov, ua rau lawv xaiv kev ntseeg tau txhim khu kev qha ntawm cov cuab yeej ua hluav taws xob tiv thaiv huab cua rau engineering thiab cov dej num siv.
Cov Nta Tseem Ceeb Ntawm Q550NH Corten Steel Phaj
1. Muaj Zog Tawm Los Muaj Zog: tus "550" qhia tau ib lub zog los lub zog ntawm 550 MPa, ua rau nws zoo tagnrho rau hnyav {3} Lub luag haujlwm siv.
2. Corrosion Kuj: Zoo li lwm cov corten steels, Q550NH ua ib qho ruaj khov, tus kheej-} Cov txheej txheem oxide, txo qhov xav tau ntawm cov duab lossis txheej.
3. Kev nyuaj thiab lub zog: haum rau kev siv nyob rau hauv ib puag ncig muaj kev muaj chaw nyob thiab sab nraum zoov uas muaj qhov ntev.
4. ** Kev Txij Nkawm Me: Cov Huab Cua Hlau Rust Txheej Kev Ua Haujlwm raws li kev tiv thaiv, txo qhov kev xav tau ntawm lub sijhawm.

Cov Khoom Siv
Q550NH Hlau PhajCov neeg muaj peev xwm txuas ntxiv, feem ntau yog rau cov qauv sab nraum zoov uas yuav tsum muaj zog thiab ntev}}}} atmmeric corrosionance. Hauv cov choj thiab cov phiaj xwm kev tsim kho, cov phaj hlau no feem ntau siv rauCov kab Maj Main, txhawb nqa qauv, trusses, thiab lub tshuab ncua kev kawmCov. Nrog apaib lub zog ntawm 550 MPAthiab atensile lub zog ntawm 650-810 mpa, nws tuaj yeem tiv thaiv hnyav thauj khoom thaum khaws cia ntev - lub sij hawm ruaj khov.
Rau lub tsev facades thiab zoo nkauj cladding, lub lawm tsimNtse oxide txheej kwv yees li 50-100 μm tuabtsis tsuas yog muab kev tiv thaiv corrosion tab sis kuj tsim qhov sib txawv reddish - xim av ncu, ua rau nws zoo tagnrho rauUa hauj lwm vaj, duab puab, tsa lub txaj paj, thiab kho kom zoo nkauj niaj hnub.
Tsis tas li ntawd, nws yog qhov tsim nyog rau kev lag luam kev lag luam xws liSilos, Cov pa taws, HVAC thiab cov khoom siv cog fais fab, raws liCov thawv, thauj khoom, tsheb thauj khoom, thiab lwm yam ntev- sij hawm thauj khoom sab nraud, ua kom muaj zog txheej txheem lub zog thaum txo ntev - kev tu thiab cov nqi pleev xim.
Nrog nws sib xyaw ntawm corrosion tsis kam, kev ua haujlwm zoo, thiab lub neej ntev,GB / T 4171 Q550NHtau dhau los ua huab cua kev xaiv hluav taws xob txhim khu kev qha rauChoj Siv, Tsim Tsev Engineering, Toj roob hauv pes architecture, thiab kev lag luam khoom.
