Txais tos rau kev lag luam wholesale customized q550nh 550mpa weathering steel phaj: siab -lub zog, corrosion{10}}resistant ntawm tus nqi sib tw los ntawm peb lub hoobkas. Cov kev pabcuam zoo thiab cov khoom zoo yog muaj.
Khoom Description
Tsim los rau kev thov cov qauv siv, Q550NH 550MPa Weathering Steel Phaj ua raws li GB / T 4171-2008, muab qhov sib npaug ntawm kev ua haujlwm siab thiab kev ua haujlwm tshwj xeeb rau atmospheric corrosion. Cov qib steel no yog ua tib zoo alloyed nrog Cu (0.20–0.55%), Cr (0.30–1.25%), Ni (0.12–0.65%), thiab kab phosphorus (tsawg dua los yog sib npaug rau 0.025%), tsim ib ntom, adherent xeb txheej (FeOOCr / FeOOH / FeOCr) tus nqi rau 1/3-1/5 ntawm cov pa roj carbon zoo tib yam, txawm tias nyob rau hauv kev lag luam lossis ntug dej hiav txwv ib puag ncig.

|---|---|---|---|---|---|---|---|---|---|
| Ntau yam | Tsawg dua lossis sib npaug li 0.16 | Tsawg dua lossis sib npaug li 0.65 | Tsawg dua los yog sib npaug rau 2.0 | Tsawg dua lossis sib npaug li 0.030 | Tsawg dua lossis sib npaug li 0.025 | 0.20–0.55 | 0.30–1.25 | 0.12–0.65 | Tsawg dua lossis sib npaug li 0.22 |
Tsim los ntawm Thermo-Mechanical Controlled Processing (TMCP), cov hlau tau dhau los ua cov dov thiab txias kom ua tiav qhov zoo -grained microstructure, ua kom muaj zog thiab ductility. Nws cov weldability yog optimized nrog pom zoo Ni/Cu- bearing flux-cored xov hlau, kom ntseeg tau tias weld hlau corrosion kuj ( atmospheric corrosion indexINtau dua lossis sib npaug rau 6.2) thiab sib piv -40℃cuam tshuam toughness.
Daim Ntawv Thov & Qhov Zoo
Zoo tagnrho rauhnyav-load, hnyav- puag ncig cov qauv, suav nrog:
Tsheb thauj mus los Infrastructure: Railway txuas hniav, tsheb thauj khoom, thiab chaw nres nkoj machinery, qhov twg siab zog txo qhov hnyav ntawm 30-50% piv rau qis dua - qib steels.
Lub zog tauj dua tshiab: Cua turbine txhawb nqa thiab lub hnub ci mounting cov qauv, tau txais txiaj ntsig los ntawm kev saib xyuas qis (kev pabcuam tsis muaj xim) thiab ntev - lub sijhawm ua haujlwm tau ntev hauv qhov qhib - huab cua.
Marine & Industrial Chaw: Cov tuam tsev hauv ntug dej hiav txwv thiab cov txheej txheem cog tshuaj, tiv thaiv cov tshuaj chloride/sulfur-laden cua los ntawm nws tus kheej- txheej tiv thaiv xeb.
Environmental & Economic tus nqi
Los ntawm kev tshem tawm qhov xav tau ntawm cov txheej txheem tiv thaiv, Q550NH txo qis VOC emissions thiab cov nqi tu lub neej thaum ua raws li kev tsim kho ntsuab. Nws 2-8x siab dua corrosion kuj txhais tau rau lub neej kev pab ntau tshaj 100 xyoo nrog tsawg thickness poob (<1mm), making it a cost-effective choice for sustainable infrastructure projects.
Engineered rau kev ntseeg siab thiab kev ua tau zoo, Q550NH 550MPa Weathering Steel Phaj teeb tus qauv rau siab -lub zog, corrosion- cov ntaub ntawv resistant nyob rau hauv niaj hnub engineering, combining technical excellence nrog ib puag ncig lub luag hauj lwm.
