Dab tsi yog qhov txawv ntawm uns N06625 thiab uns N08825?
Nickel alloy 625 yog cov khoom siv nickel-chromium-molybdenum-niobium alloy nrog cov ntsiab lus tseem ceeb ntawm yam tsawg 58% npib tsib xee, tseem hu ua Inconel 625 lossis UNS NO6625, siv rau cov kav dej raws li tus qauv ASTM B444, lossis rau coils raws li ASTM B443. . Lwm cov tshuaj muaj xws li 20% mus rau 23% chromium, 3.15% mus rau 4.15% columbium + tantalum, 8.0% mus rau 10.0% molybdenum, a Qhov siab tshaj plaws ntawm 1.0% columbium thiab cobalt, thiab qhov siab tshaj ntawm 5.0% hlau.
Qhov ceev 8.4g / cm3, melting point 1290-1350 degree . Nws muaj corrosion kuj zoo heev rau inorganic acids thiab ntau yam corrosive media nyob rau hauv oxidizing thiab txo ib puag ncig.
Inconel 625 / Inconel 625 / UNS N06625 Khoom
Inconel Alloy 625 yog ib qho tsis sib nqus, corrosion-resistant, oxidation-resistant, npib tsib xee-chromium-raws li cov khoom siv ntxiv dag zog deformed high-temperature alloy.
Ib qho kev daws teeb meem ntxiv dag zog rau npib tsib xee-raws li deformed high-temperature alloy nrog molybdenum thiab niobium ua cov ntsiab lus tseem ceeb. Inconel 625 lub zog siab yog vim muaj kev sib xyaw ua ke ntawm molybdenum thiab niobium ntawm ib qho alloyed nickel-chromium matrix. Qhov sib ntxiv ntawm molybdenum ua haujlwm nrog niobium los ua kom cov hlau matrix harden, muab lub zog siab yam tsis tas yuav tsum tau siv cov cua kub hnyav.
Inconel 625 yog qhov tsis tshua muaj neeg tiv taus rau ntau qhov chaw tshwj xeeb corrosive, nrog rau kev kub ntxhov xws li oxidation thiab carburization, nrog rau corrosion. Vim tias cov refractory Co thiab Mo yog cov kev daws teeb meem hauv cov nickel-chromium matrix, 625 muaj lub zog zoo thiab tawv tawv ntawm qhov kub thiab txias li 2000 degree F (1093 degree).
Inconel 625 Composite Pipe Liner / Nickel Alloy 625 Overlay
Cov khoom siv Inconel 625 tuaj yeem hla los yog kab ntawm cov kav dej muaj zog carbon steel xws li API 5L X60, X65, Siab corrosion kuj. Ib puag ncig muaj xws li dej hiav txwv, airspace, tshuaj nroj tsuag, thiab petrochemical industries.
Sab hauv cladding lossis hauv ob sab phlu ntawm carbon steel kav nrog Inconel 625 cov khoom tau dhau los ua ib qho kev xaiv nrov los daws cov teeb meem corrosion thiab txuag cov nqi tseem ceeb.
Qhov zoo ntawm Inconel 625
Siab tensile zog thiab siab corrosion qaug zog kev ua tau zoo;
High resistant rau oxidation ntawm qhov kub thiab txias mus txog 1050C.
Kev ua haujlwm zoo thiab kev ua haujlwm vuam zoo;
Zoo heev corrosion kuj thiab oxidation kuj;
Resistant rau kev nyuaj siab corrosion nyob rau hauv ntsev tsuag cua;
Kev tiv thaiv zoo rau pitting corrosion, crevice corrosion thiab intergranular corrosion;
Cov cuab yeej zoo heev ntawm ob qho tib si qis thiab kub heev;
Yuav luag tag tiv thaiv chloride-induced kev nyuaj siab corrosion cracking;
Kev tiv thaiv zoo rau cov kua qaub (xws li nitric, phosphoric, sulfuric thiab hydrochloric acids) thiab alkalis ua rau nws muaj peev xwm tsim cov txheej txheem nyias nrog kev hloov pauv kub.
Nickel alloy 625 / Inconel 625 / UNS N06625 muaj qhov tsis tshua muaj corrosion nyob rau hauv ob qho tib si marine thiab non-marine ib puag ncig, muaj kev tiv thaiv zoo rau seawater corrosion, tiv thaiv corrosion los ntawm ntau cov ntsev tov, thiab zoo corrosion kuj rau HNO3 phosphoric acid. Resistant rau cua sov rau boiling point. Nws kuj tseem muaj qhov tsis kam tiv thaiv HCl hauv qab no thiab qis-concentration sulfuric acid. Lub alloy yuav dhau lub hnub nyoog hardening tom qab siv mus sij hawm ntev ntawm 550-700 degree, uas yuav ua rau cov yas ntawm N06625/No6625 alloy yuav txo. thiab tsis kam mus rau chloride ion kev nyuaj siab corrosion cracking, ua rau nws yog ib qho kev xaiv zoo heev rau seawater thiab aerospace daim ntaub ntawv.
