Tom ntej: Inconel 625 Alloy
Inconel625 alloy yog ib qho kev daws teeb meem uas muaj zog nickel-raws li deformed high-temperature alloy nrog molybdenum thiab niobium ua cov ntsiab lus tseem ceeb. Nws muaj kev tiv thaiv corrosion zoo heev thiab oxidation tsis kam. Nws muaj zog tensile zoo thiab qaug zog zog los ntawm qhov kub thiab txias mus rau 980 degree, thiab yog resistant rau Stress corrosion nyob rau hauv ntsev tsuag cua. Yog li ntawd, nws tuaj yeem siv dav hauv kev tsim cov tshuab aerospace, cov khoom siv hauv aerospace thiab cov khoom siv tshuaj. Cov hlau no yog siv los tsim cov khoom xws li cav cav, coj vanes, mounting npoo thiab chim, thiab cov kav dej loj. Nws tau dhau qhov kev ntsuam xyuas daim ntawv thov thiab muaj qhov ua haujlwm siab tshaj plaws ntawm 950 degree. Cov hlau muaj qee yam kev laus tom qab siv mus ntev ntawm 550 txog 700 degree. Lub hardening tshwm sim ua rau qee qhov txo qis hauv plasticity ntawm cov hlau.
Alloy Properties
1. Nws muaj kev tiv thaiv zoo heev tiv thaiv ntau yam corrosive media hauv oxidizing thiab txo qhov chaw.
2. Kev tiv thaiv zoo heev rau pitting corrosion thiab crevice corrosion, thiab yuav tsis tsim kev ntxhov siab corrosion tawg los ntawm chloride
3. Kev tiv thaiv zoo heev rau inorganic acid corrosion, xws li nitric acid, phosphoric acid, sulfuric acid, hydrochloric acid thiab sib xyaw acids ntawm sulfuric acid thiab hydrochloric acid, thiab lwm yam.
4. Zoo heev tiv thaiv corrosion los ntawm ntau yam inorganic acid tov tov
5. Thaum qhov kub nce mus txog 40 degree, nws tuaj yeem pom zoo corrosion kuj nyob rau hauv hydrochloric acid daws ntawm ntau yam concentrations.
6. Zoo processability thiab weldability, tsis muaj tom qab weld tawg rhiab heev
7. Kev tsim cov ntawv pov thawj ntawm cov hlab ntsha siab nrog phab ntsa kub ntawm -196 ~ 450 degree
8. Muaj ntawv pov thawj los ntawm NACE tus qauv ntawm American Society of Corrosion Engineers (MR-01-75) kom ua tau raws li tus txheej txheem siab tshaj plaws VII rau kev siv hauv qhov chaw qaub qaub.
Cov chaw thov
Tsawg carbon alloy 625 tom qab mos annealing yog dav siv hauv kev lag luam tshuaj. Nws zoo corrosion kuj thiab siab zog pab kom nws yuav siv tau raws li nyias structural Cheebtsam. Alloy 625 tuaj yeem siv rau hauv cov ntawv thov uas nws raug dej hiav txwv thiab raug rau cov neeg kho tshuab siab. Tej thaj chaw thov:
1. Cov txheej txheem ntawm cov txheej txheem tshuaj organic uas muaj cov tshuaj chlorides, tshwj xeeb tshaj yog siv cov kua qaub chloride catalysts.
2. Digesters thiab bleaching tanks rau kev lag luam pulp thiab ntawv
3. Absorption ntauwd, reheater, flue gas inlet baffle, kiv cua (humidity), agitator, qhia phaj thiab flue hauv flue gas desulfurization system
4. Rau kev tsim cov khoom siv thiab cov khoom siv hauv cov pa roj qaub
5. Acetic acid thiab acetic anhydride cov tshuaj tiv thaiv generator
6. Sulfuric acid condenser
