Dab tsi yog qhov txawv ntawm Inconel Nickel Alloys 625, 330 thiab 600?
Tej zaum koj yuav paub txog Inconel tsev neeg ntawm high-nickel alloys. Cov tsev neeg ntawm cov alloys no muaj npe nrov rau nws qhov kev ua tau zoo nyob rau hauv huab cua kub, ua rau txhua qhov Inconel nickel alloy variant nrov heev rau siv rau hauv cov ntawv siv rauv xws li kev kho cua sov lossis annealing steels. Txawm li cas los xij, qhov sib txawv ntawm Inconel ntau yam ntawm cov khoom siv nickel alloy yog dab tsi? Qhov no yog ib lo lus nug feem ntau nug los ntawm Muyan Alloy salesmen. Qhov tseeb, ib tus neeg siv khoom tsis ntev los no tau sim qhov chaw uas lawv muab lawv cov khoom tso rau hauv lub cub tawg ntawm 1975 degrees Fahrenheit rau ib teev thiab xav paub seb qhov twg ntawm peb qhov sib txawv Inconel alloys yuav zoo tshaj rau lawv daim ntawv thov: 330, 600 lossis 625?
Txhawm rau pab teb cov lus nug no, ntawm no yog qhov sib piv ceev ntawm peb cov hlau tshwj xeeb kub kub:
Kev 330
Txawm hais tias nws yog ib feem ntawm Inconel tsev neeg ntawm tshav kub-resistant hlau alloys, 330 feem ntau hu ua Incoloy los yog RA330. Nrog cov ntsiab lus npib tsib xee ntawm 34% thiab 37% thiab cov ntsiab lus chromium ntawm 17% thiab 20%, Incoloy yog qhov tsis txaus ntseeg oxidation ntawm qhov kub siab txog 1148 degree thiab muaj peev xwm carburize thiab nitride.
Kev hloov pauv sai ntawm qhov kub thiab txias (feem ntau hauv cov ntawv kho cua sov) tsis yog qhov teeb meem loj rau 330 alloy vim nws tiv thaiv thermal shock. Zoo li ntau Inconel alloys, 330 khaws cov qib loj ntawm tensile lub zog nyob rau hauv huab cua kub piv rau cov hlau alloys.
Qhov tseeb, nyob rau hauv Alloy Performance Guide, Rolled Alloys teev RA330 raws li muaj "zoo dua" (saum toj no qhov nruab nrab) cov khoom nyob rau hauv lub zog, oxidation tsis kam, carburization tsis kam, thiab leej faj oxidation kuj, thaum tseem yog Rated "Zoo tshaj" nyob rau hauv thermal shock kuj ntawm cov. kub kub alloys muaj.
inconel 600
Inconel600 yog cov khoom siv hluav taws xob oxidation nrov heev. Nrog rau qhov tsawg kawg nkaus npib tsib xee cov ntsiab lus ntawm 72%, cov hlau alloy no muaj ntau tshaj ob npaug ntawm cov ntsiab lus nickel ntawm Incoloy 330.
Thaum qhov no pab txhim kho cov hlau tsis kam mus rau qhov kub-kub oxidation thiab carburization, nws ua rau cov hlau raug leej faj tua. Raws li tau piav qhia hauv Rolling Alloys Guide, Inconel 600 yog siv los oxidize sulfur, txo cov sulfur lossis molten hlau xws li tooj liab, zinc lossis magnesium. Tab sis nws muaj lub zog tensile zoo, siab tshaj qhov nruab nrab tiv thaiv oxidation thiab thermal shock, thiab zoo tshaj plaws-hauv-chav ua haujlwm rau carburization. Nws kuj yog qhov tsis txaus ntseeg tiv thaiv chloride kev nyuaj siab corrosion tawg yog tias qhov kev ntxhov siab tau txo qis.
Inconel 625
Hais txog cov ntsiab lus npib tsib xee, Inconel625 yog nruab nrab ntawm alloy 330 thiab 600, nrog tsawg kawg nkaus nickel ntsiab lus ntawm 58%. Cov ntsiab lus chromium yog nyob nruab nrab ntawm 20-23%, uas yog cov khoom siv ntau tshaj plaws hauv cov hlau. Qhov sib ntxiv ntawm niobium thiab molybdenum txhim kho kev ua tau zoo ntawm cov hlau ntawm qhov sib txawv ntawm qhov kub thiab txias, uas yog vim li cas Inconel600 muaj lub zog zoo thiab tawv tawv hauv qhov kub ntawm 0 degree txog 1093 degree.
Cov hlau tseem muaj qhov tshwj xeeb tshaj plaws ntawm kev sib tsoo lub zog, qaug zog ua haujlwm thiab chloride pitting / crevice corrosion kuj. Tsis tas li ntawd, cov hlau no yooj yim heev rau vuam piv rau lwm yam Inconel nickel alloys. Pom zoo siv rau cov hlau no muaj xws li dav hlau cav tso cov kav dej, flare pawg, cov khoom siv dej hiav txwv thiab cov khoom siv tshuaj lom neeg vim nws cov tshuaj lom neeg thiab kub tsis kam.
Hauv kev ntsuam xyuas corrosion ntawm dov alloys, 625 qhov kev tiv thaiv rau oxalic acid yog qhov tshwj xeeb tshaj yog piv rau lwm cov ntaub ntawv, nrog rau cov khoom siv tsuas yog 6.0 mils / xyoo ntawm corrosion nyob rau hauv 10% boiling tov ntawm oxalic acid. Hauv kev sib piv, 316L stainless hlau tau ntsib 44.9 mils / xyoo ntawm corrosion hauv tib cov tshuaj. Txawm li cas los xij, nws cov tshuaj tiv thaiv rau sulfuric acid tsis tshua muaj txiaj ntsig, ntawm 37mils / xyoo hauv 10% da dej.
Yog li cov ntaub ntawv twg yog qhov zoo tshaj plaws rau koj cov kev xav tau?
GNEE Steel xav kom koj: Nyob ntawm seb koj daim ntawv thov txheej txheem zoo li cas, cov tshuaj dab tsi, yog tias muaj, yuav koom nrog? Inconel 600 muaj qhov kub thiab txias tsis kam, tab sis tsis pub tshaj 330, ua rau nws tsis haum rau txhua daim ntawv thov uas cuam tshuam nrog kev siv sulfuric acid compounds. Nyob rau tib lub sijhawm, 330 muaj kev tiv thaiv zoo rau sulfur oxidation tab sis tsis txo cov ntsiab lus sulfur. Inconel 625 feem ntau resistant rau feem ntau cov acids tab sis tej zaum yuav raug nqi ntau tshaj qhov qis nickel-muaj 330 alloy.
