Core Chemistry: Ntau dua li "High Nickel"

Ntau tus neeg tswj xyuas kev yuav khoom yuam kev C276 rau lwm tus nqi npib tsib xee alloy xwb. Nws lub hwj chim tiag tiag nyob rau hauv cov nyhuv synergisticMolybdenum (15-17%)thiabTungsten (3-4.5%).

Lub Bane ntawm Txo Media:Tsis zoo li 316 stainless hlau, C276 tseem nyob ruaj khov nyob rau hauv kub, paug ntxhia acids, xws li formic thiab acetic acids uas muaj chlorides.
Qhov qis-Carbon Shield:Nrog rau cov ntsiab lus carbon txwv tsawg dua los yog sib npaug rau 0.010%, C276 txo cov nplej- ciam teb carbide nag lossis daus hauv tshav kub- thaj chaw cuam tshuam (HAZ) thaum vuam. Qhov no txhais tau hais tias cov kav dej feem ntau tuaj yeem muab tso rau hauv kev pabcuam "raws li -welded" yam tsis tas yuav tsum muaj kev sib tw ua haujlwm -weld solution annealing.

Tiag -Kev Ua Haujlwm Hauv Ntiaj Teb

Hauvsiab -cov av noo saline ib puag nciglos yog tshwj xeebFlue Gas Desulfurization (FGD)systems, txheem alloys succumb sai heev rau localized pitting.

Pitting Resistance Equivalent Number (PREN):C276 feem ntau boasts PREN tshaj 60, ho siab tshaj 35-45 ntau ntawm Super Duplex steels.
Stress Corrosion Cracking (SCC):Hauv cov roj qaub thiab roj av uas muaj H2S, C276 piping ua tau raws li NACE MR0175 cov qauv, ua rau nws yog ib qho ntawm ob peb txoj kev xaiv rau kev tsim cov tubing downhole.

Seamless vs Welded C276

ASTM B622 Seamless Yeeb Nkab:Cov txheej txheem kub rau siab -siab, kev pabcuam ua kua dej tuag. Nws cov qauv monolithic tshem tawm txoj kev pheej hmoo ntawm galvanic corrosion ntawm weld seam.

ASTM B619 / B626 Welded Yeeb Nkab:Nrog rau niaj hnub Plasma Arc Vuam (PAW) thiab txias-txoj kev kos duab, siab- zoo welded tubing muaj tus nqi- siv tau zoo rau qhov loj - txoj kab uas hla atmospheric hloov chaw.
