Inconel 601 has a chromium content of 14-17 percent , while Inconel 625 has a chromium content of 20-23 percent . Qhov ntau tshaj cov ntsiab lus ntawm cov ntsiab lus ntawm Inconel 625 muab kev tiv thaiv oxidation zoo dua, ua rau nws zoo tagnrho rau cov tshuaj hnyav thiab acidic ib puag ncig.
Lwm cov ntsiab lus
Inconel 601
Inconel 6 {0 2 muaj cov ntsiab tshwj xeeb xws li txhuas (1. {}.}}. Tsawg tus nqi ntawm cov leej faj (txog li 0.015 feem pua) txhim kho machinability.
Inconel 625
Inconel 625 muaj cov ntsiab lus tshwj xeeb xws li Molybdenum (ntau dua 8 feem pua), thiab tantalum, thiab tantalum tsis muaj zog thiab corrosion tsis kam, tshwj xeeb tshaj yog hauv kev txo ib puag ncig. Niobium thiab tantalum txhim kho cov khoom siv los ntawm kev ntxiv dag zog rau cov alloy.
Phosphorus thiab manganese cov ntsiab lus
Inconel 625 tau nruj nreem cov ntsiab lus phosphorus thiab manganese cov ntsiab lus los txhim kho lub zog nkag thiab ua tau zoo. Inconel 601, los ntawm kev sib piv, tsis muaj cov phosphorus ntau thiab ntau dua so kev tswj hwm manganese.
Cov ntsiab lus carbon
Cov ntsiab lus carbon ntawm cov alloys sib txawv. Inconel 6 {0 1 muaj cov ntsiab lus carbon ua ntej rau {}}. 10 feem pua rau kev ua kom muaj kev ruaj khov thiab oxidation tiv thaiv nyob rau ntawm qhov kub. Inconel 625 muaj qis dua cov ntsiab lus carbon (nyob ib ncig ntawm 0.10 feem pua lossis tsawg dua) kom tiv thaiv carbide nag lossis tswj hwm corrosion.
Zuag qhia tag nrho
Lub cim sib txawv ntawm inconel 601 thiab Inconel 625 muab cov txiaj ntsig zoo sib txawv. Cov ntsiab lus ntau dua thiab Molybdenum cov ntsiab lus ntawm inconel 625 muab nws zoo tshaj plaws corrosion tsis kam, ua rau zoo rau kev ua haujlwm ib puag ncig. Lub npib tsib xee, chromium, txhuas thiab sulfur sib xyaw ntawm inconel) muab nws zoo rau kev tsim cov khoom tawg thiab cov khoom siv kub.
Corrosion Kuj
Corrosion Kuj Txheej txheem cej luam
Rau cov ntawv thov nyob rau hauv cov chaw hnyav, nws yog qhov tseem ceeb los xaiv cov ntaub ntawv nrog muaj zog corrosion tsis kam. Ob qho tib si inconed 601 thiab Inconel 625 yog paub zoo rau lawv corrosion tsis kam, thiab nkawd ob leeg ua tau zoo nyob rau hauv cov kev sib txawv vim lawv cov tshuaj sib txawv.
Inconel 601
Inconel 601 paub txog nws qhov kev kub kub zoo siab tiv thaiv, tsim cov txheej ruaj khov kho oxide uas txwv tsis pub ntxiv cov khoom. Lub corrosion tsis kam ntawm inconel 601 suav nrog:
Oxidation zoo ua tsis kam: Cov kub ua hauj rau txog 1200 degree (2200 degree f), zoo tagnrho rau cov ntawv thov kom kub siab.
Chloride Kuj: Cov kev tiv thaiv zoo heev rau kev tawg vim los ntawm chloride ions, zoo haum rau cov tshuaj thiab cov tub rog ib puag ncig.
Corrosive resistance: Zoo ua rau cov tshuaj ua kom haum xws li caustic dej qab zib.
Inconel 625
Inconel 625 Alloy yog nplua nuj nyob hauv chromium thiab molybdenum, muab cov corrosion tsis kam nyob rau ntau thaj chaw. Nws corrosion tiv taus suav nrog:
General corrosion resistance: kev tiv thaiv zoo heev rau ntau yam ntawm cov neeg sawv cev ntawm cov neeg sawv cev, suav nrog cov chaw acidic thiab alkaline ib puag ncig, ua rau nws dav siv hauv kev ua lag luam thiab lwm yam lag luam.
Corrosion Kuj: Txhim kho kom tiv thaiv kom haum rau cov tshuaj lom neeg xws li sulfuric acid, hydrofluoric acid, haum rau ib puag ncig corrosive.
Saltw dej corrosion: kev ua tau zoo hauv Saltwater ib puag ncig, zoo tagnrho rau cov kev siv roj av thiab cov roj pov thiab roj platform thiab roj platform thiab roj platform thiab roj platform.
Kev kub siab corrosion: zoo heev corrosion txawm hais tias ntawm kev tiv thaiv kub, muab kev tiv thaiv kub tawm tsam cov kev kub kub siab thiab lwm hom kev kub siab corrosion.
Kev sib piv sib piv
Inconel 601 vs. inconel 625:
Inconel 601: Zoo tshaj plaws rau cov oxidation siab tiv taus thiab chloride ion ib puag ncig.
Inconel 625: dav dav tawm rau kev corrosion, haum rau ntau hom acids, ntsev thiab corrosive tshuaj.
Qhov kev xaiv ntawm inconel 601 thiab Inconel 625 nyob ntawm cov kev cai ib puag ncig thiab hom corrosion. Nkag siab txog lawv cov khoom sib txawv ua kom ntseeg tau cov khoom raug yog xaiv rau cov ntawv thov.
