Inconel625/N06625/2.4856 npib tsib xee-raws li alloy muaj pes tsawg leeg
Txheej txheem cej luam ntawm Incone l625 nta thiab daim ntawv thov teb:
Lub alloy yog 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. Nws muaj kev tiv thaiv corrosion zoo heev thiab oxidation tsis kam, zoo tensile zog thiab qaug zog zog los ntawm qhov kub thiab txias mus rau 980 degree, thiab yog ntsev resistant. Kev ntxhov siab corrosion hauv huab 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.

Inconel625 muaj cov yam ntxwv hauv qab no:
1. Nws muaj kev tiv thaiv zoo heev tiv thaiv ntau yam corrosive media hauv oxidizing thiab txo ib puag ncig[1]
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.
Metallographic qauv ntawm Inconel625
625 yog lub ntsej muag-centered cubic lattice qauv. Thaum khaws cia ntawm li 650 degree rau lub sijhawm ntev txaus, cov pa roj carbon monoxide thiab tsis ruaj khov quaternary theem yuav los nag thiab hloov mus rau theem ruaj khov Ni3 (Nb, Ti) orthorhombic lattice. Tom qab cov khoom siv ntxiv dag zog, molybdenum thiab niobium Cheebtsam hauv nickel-chromium matrix yuav txhim kho cov khoom siv ntawm cov khoom, tab sis cov yas yuav raug txo.
Corrosion kuj ntawm Inconel625
Alloy 625 qhia tau hais tias zoo heev corrosion kuj nyob rau hauv ntau yam xov xwm. Zoo heev rau pitting, crevice corrosion, intergranular corrosion thiab yaig nyob rau hauv chloride media. Nws muaj kev tiv thaiv zoo rau inorganic acid corrosion, xws li nitric acid, phosphoric acid, sulfuric acid, hydrochloric acid, thiab lwm yam. Nws kuj muaj kev tiv thaiv rau alkali thiab organic acid corrosion nyob rau hauv oxidizing thiab txo ib puag ncig. Ua haujlwm zoo rau chloride ion txo kev ntxhov siab corrosion cracking. Yuav luag tsis muaj corrosion nyob rau hauv seawater thiab industrial gas ib puag ncig, thiab nws muaj siab corrosion kuj rau seawater thiab ntsev tov, kuj nyob rau hauv high kub. Tsis muaj rhiab heev thaum vuam. Resistant carbonization thiab oxidation nyob rau hauv static los yog cyclic ib puag ncig, thiab resistant rau corrosion los ntawm chlorine-muaj gases
