Alloying Elements

Cov ntsiab lus tseem ceeb ntawm ASTM A709GR50W Corten steel suav nrog tooj liab (Cu), chromium (Cr), npib tsib xee (Ni), thiab phosphorus (P). Tooj liab yog ib qho tseem ceeb ntawm cov hlau uas ua rau muaj kev tiv thaiv xeb ntawm cov hlau. Nws feem ntau muaj cov ntsiab lus los ntawm 0.25% - 0.55%. Chromium pab txhawm rau txhim kho corrosion - tiv taus cov khoom thiab feem ntau muaj nyob rau hauv cov nyiaj ib ncig ntawm 0.40% - 0.70%. Nickel yog ntxiv los txhim kho tag nrho cov kev ua tau zoo thiab ductility ntawm cov hlau, nrog rau cov ntsiab lus ntawm 0.02% - 0.10%. Phosphorus kuj plays lub luag hauj lwm nyob rau hauv lub corrosion - kuj mechanism thiab feem ntau yog nyob rau hauv ntau ntawm 0.07% - 0.15%.

 

Mechanical Properties

Lub zog

Raws li tau hais ua ntej, qhov tsawg kawg nkaus lub zog ntawm ASTM A709GR50W yog 50 ksi (345 MPa), thiab lub zog tensile feem ntau yog nyob rau hauv thaj tsam ntawm 65 - 85 ksi (448 - 586 MPa). Cov txiaj ntsig ntawm lub zog no ua rau nws tsim nyog rau ntau yam kev siv cov qauv, xws li hauv kev tsim cov choj, vaj tse, thiab lwm yam kev tsim kho uas nws tuaj yeem nqa tau cov khoom thauj los ntawm kev tsav tsheb, cua, daus, thiab lwm yam quab yuam.

 

Weldability

ASTM A709GR50W Corten steel muaj qhov zoo weldability. Cov ntsiab lus tsis tshua muaj carbon thiab kev sib xyaw ua ke ntawm cov ntsiab lus alloying kom ntseeg tau tias nws tuaj yeem welded siv cov txheej txheem vuam xws li shielded hlau arc vuam (SMAW), roj hlau arc vuam (GMAW), thiab flux - cored arc vuam (FCAW). Thaum lub sij hawm welding, nws yog ib qho tseem ceeb uas yuav tsum tau ua raws li cov txheej txheem welding pom zoo kom tswj tau cov neeg kho tshuab thiab corrosion - tsis kam ntawm cov pob qij txha welded.

Corrosion - Resistance Mechanism

Thaum raug cov huab cua, cov ntsiab lus alloying hauv Corten steel, tshwj xeeb tshaj yog tooj liab, hnov ​​​​mob nrog oxygen thiab noo noo los tsim cov txheej txheem xeb thiab ruaj khov. Cov txheej xeb no txawv ntawm cov xeb uas tshwm sim ntawm cov hlau zoo tib yam. Cov txheej tiv thaiv xeb ntawm Corten steel yog ntom thiab ua raws li kev thaiv, tiv thaiv kev nkag mus ntxiv ntawm oxygen thiab noo noo, yog li txo qis tus nqi ntawm corrosion. Sij hawm dhau mus, cov xim ntawm cov txheej xeb tuaj yeem hloov pauv los ntawm qhov pib reddish - xim av mus rau ib qho tsaus, xim ruaj khov, muab cov hlau zoo nkauj zoo nkauj thaum tseem tuav nws cov qauv kev ntseeg siab.

 

 

 

 

 

 

ASTM A709GR50W corten steel phaj

Lub zog siab qis alloy steel phaj ASTM A709GR50W kuj muaj npe hu ua weathering steel phaj A709 Qib 50W hauv qhov kom zoo dua ntawm nws cov cuab yeej hauv huab cua corrosion kuj.Raws li cov ntsiab lus sib txawv tseem ceeb muaj, A709 Qib 50W tau muab faib ua A709Gr50w hom A, A709Gr50w hom B, A709Gr50w hom C.Low alloy steel phaj A709 Qib 50W kuj muaj qhov tshwj xeeb ASTM A 588 / A 588M A588 Qib A, A588 Qib B thiab A588 Qib C.Low alloy steel phaj A709 Qib 50W kuj muaj tib yam tsawg kawg nkaus txwv kev tawm dag zog ntawm A709. Qib 50 steel phaj.

 

 

 

Daim ntawv thov

Kev tsim kho choj

Nws yog dav siv nyob rau hauv kev tsim kho cov choj, tshwj xeeb tshaj yog rau cov choj girders, decks, thiab kev txhawb nqa cov qauv. Kev sib xyaw ua ke ntawm lub zog thiab corrosion - tsis kam ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov txuas hniav uas raug rau cov ntsiab lus, vim nws tuaj yeem txo cov nqi kho mob cuam tshuam nrog kev pleev xim thiab tiv thaiv xeb. Piv txwv li, nyob rau hauv cov ntug dej hiav txwv los yog cheeb tsam uas muaj av noo siab, ASTM A709GR50W Corten steel txuas hniav tuaj yeem tiv taus cov corrosive los ntawm ntsev - laden huab cua thiab los nag.

Architectural Structures

Hauv kev siv architectural, nws yog siv rau lub tsev facades, ru tsev, thiab lwm yam sab nrauv. Lub ntuj xeb - xim xim ntawm cov hlau tuaj yeem ntxiv qhov muaj txiaj ntsig zoo nkauj rau lub tsev tsim. Nws tuaj yeem siv los tsim niaj hnub, kev lag luam - saib cov qauv lossis sib xyaw nrog ntuj puag ncig. Piv txwv li, nyob rau hauv ib lub tsev khaws puav pheej los yog ib lub chaw coj noj coj ua, kev siv Corten steel daim hlau rau cov phab ntsa sab nrauv tuaj yeem muab qhov tshwj xeeb thiab ruaj khov.

Industrial thiab Infrastructure Projects

Nws kuj yog siv nyob rau hauv industrial cov nroj tsuag, railway infrastructure, thiab lwm yam infrastructure tej yaam num. Hauv cov chaw tsim khoom, nws tuaj yeem tiv taus cov tshuaj lom neeg thiab cov pa phem hauv huab cua. Hauv kev siv kev tsheb ciav hlau, nws tuaj yeem siv rau cov platforms, cov teeb liab yees, thiab lwm yam qauv uas raug huab cua thiab ntau yam ib puag ncig.
