Corten B hlauyog lub siab -lub zog huab cua steel tsim rau cov ntawv thov uas xav tau kev tiv thaiv corrosion, siab zog, thiab kav ntev.
Corten B hlau
Nws yog dav siv nyob rau hauv aeroderivative gas turbine tso systems, railway wagons, txuas hniav, chimneys, boilers, dej kav dej, thiab industrial ntim.
Vim nws cov tshuaj lom neeg muaj pes tsawg leeg thiab kev ua haujlwm thermomechanical, Corten B muab 3-8 npaug ntawm atmospheric corrosion resistance dua li cov pa roj carbon zoo tib yam, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau sab nraum zoov thiab kev lag luam.
Chemical Composition ntawm Corten B Weathering Steel
Corten B steel yog tsim los ntawm kev ntxiv me me tab sis muaj txiaj ntsig zoo ntawm cov ntsiab lus alloying rau cov pa roj carbon zoo tib yam. Cov ntsiab lus no tsim ib tus kheej - txheej tiv thaiv xeb, tseem hu ua patina, uas tsim ib txwm dhau sijhawm thiab tiv thaiv cov tub ntxhais hlau los ntawm corrosion.
| Element | Ntau yam (%) | Muaj nuj nqi |
|---|---|---|
| Cov pa roj carbon (C) | Tsawg dua lossis sib npaug li 0.16 | Khaws weldability thiab toughness |
| Silicon (Si) | 0.30–0.50 | Deoxidation thiab txhim kho lub zog |
| Manganese (Mn) | 0.80–1.25 | Nce hardenability thiab mechanical kev ua tau zoo |
| Phosphorus (P) | Tsawg dua lossis sib npaug li 0.03 | Txhawb kev tiv thaiv xeb txheej tsim |
| Sulfur (S) | Tsawg dua los yog sib npaug li 0.03 | Txhim kho machinability, khaws cia tsawg kawg kom tsis txhob brittleness |
| Chromium (Cr) | 0.40–0.65 | Txhim kho corrosion kuj thiab siab -kub stability |
| Nickel (Ni) | 0.25–0.40 | Txhim kho toughness thiab qaug zog kuj |
| Copper (Cu) | 0.20–0.40 | Txhim kho atmospheric corrosion kuj |
| Vanadium (V) | 0.02–0.10 | Refines grain thiab nce lub zog |
Qhov kev sib xyaw ua ke no ua kom muaj lub zog tensile zoo, lub zog tawm los, ductility, thiab qaug zog tiv thaiv, thaum tuav zoo weldability, machinability, thiab formability.
Mechanical Properties ntawm Corten B Weathering Steel
Corten B steel tswj kev ua haujlwm siab ua haujlwm thoob plaws ntau qhov tuab, ua rau nws tsim nyog rau kev siv cov qauv thiab sab nraum zoov.
| Thickness (hli) | Yield zog (MPa) | Tensile zog (MPa) | Elongation (%) |
|---|---|---|---|
| Tsawg dua los yog sib npaug li 16 | 355 | 470–630 | Ntau tshaj los yog sib npaug rau 20 |
| >16 Tsawg dua lossis sib npaug li 50 | 345 | 470–630 | Ntau tshaj los yog sib npaug rau 20 |
Qhov cuam tshuam lub zog ntawm daim hlau Ntau dua los yog sib npaug ntawm 10 hli yog tsawg kawg yog 27J ntawm -20 degree, ua kom ntseeg tau tias ruaj khov txawm tias nyob hauv qhov chaw txias.
Corten B steel tau ua tiav zoo siv hauv aeroderivative gas turbine exhausts thiab lwm yam siab -kev siv kub. Nws tiv thaiv oxide txheej (xeb crust) tiv thaiv cov hlau los ntawm kev xeb ntxiv atmospheric corrosion.
Cov ntsiab lus tseem ceeb:
Cov ntsiab lus tooj liab (0.2-0.4%) txhim khu kev tiv thaiv corrosion tab sis muaj qhov cuam tshuam tsawg heev ntawm oxidation ntawm qhov kub siab tshaj 454℃(850℃F).
Chromium txo qhov cuam tshuam rau graphitization thiab ua kom cov qauv ruaj khov nyob rau hauv nruab nrab cua sov.
Rau ntev ntev -kub raug, Corten B yuav muaj kev nkag los yog me me deformation, yog li tsim thiab thickness yuav tsum tau soj ntsuam raws li.
Corten B tuav nws txoj kev tiv thaiv corrosion thaum xav tau kev saib xyuas tsawg dua thiab tshem tawm cov xim rau feem ntau cov ntawv thov sab nraum zoov.
Kev siv ntawm Corten B Weathering Steel
Corten B steel yog dav siv vim nws cov huab cua kev ua tau zoo, kev thov kom zoo nkauj, thiab kev ntseeg siab ntawm txhua yam:
- Infrastructure: choj, chimneys, boiler lug, thiab industrial ntim.
- Tsheb thauj mus los: Railway wagons, ua liaj ua teb vans, thiab tsheb.
- Architectural: Cladding, sculptures (piv txwv li, Angel ntawm sab qaum teb), cov rooj tog hauv nroog, thiab planters.
- Marine thiab Industrial Equipment: Cov kav dej, kiv cua, tso pa tawm, thiab tso tsheb hlau luam.
Lub patina uas txhim kho lub sij hawm muab ob qho tib si kev tiv thaiv corrosion thiab cov txiv kab ntxwv tshwj xeeb -xim av zoo nkauj, ua Corten B haum rau kev ua haujlwm thiab cov qauv zoo nkauj.
