Incoloy825 alloy tsis tuaj yeem tsim hauv qab 650 degrees. Cov hlau yog tsim rau kev kho cua sov ruaj khov ntawm 940 degrees, thiab qhov nruab nrab annealing yog qhov zoo dua siab dua 1050 degrees. Vuam siv nickel-based hlau xws li: 00cr22ni61mo9NB.
Incoloy825 muaj ntau yam kev tiv thaiv corrosion thiab feem ntau siv hauv kev lag luam tshuaj, dej hiav txwv kub thiab hydrometallurgy. Nws yog tsuas yog siv nyob rau hauv lub tshav kub exchangers, kav, li qub thiab dej twj tso kua mis uas tuav kub sulfuric acid, chloride-muaj kev daws teeb meem, sulfurous acid thiab lwm qhov chaw. thiab lwm yam., nws kuj yog siv dav hauv kev ua liaj ua teb ntawm cov ntoo pulp extractors thiab cov dej sib sib zog nqus hauv cov ntawv ua lag luam.
Alloy Properties
1. Resistance rau kev nyuaj siab corrosion cracking
2. Resistance rau pitting corrosion thiab crevice corrosion
3. Anti-oxidation thiab non-oxidizing kub acid zog
4. Nws muaj cov cuab yeej zoo hauv chav tsev kub thiab kub siab txog 550 degree.
5. Daim ntawv pov thawj rau cov hlab ntsha siab nrog kev tsim khoom kub txog 450 degree.
Incoloy825 alloy (UNS N08825) yog austenitic nickel hlau chromium alloy nrog ntxiv molybdenum, tooj liab thiab titanium. Nws tau raug tsim los muab kev tiv thaiv corrosion zoo heev hauv oxidizing thiab txo qhov chaw. Lub alloy yog resistant rau chloride kev nyuaj siab corrosion cracking thiab pitting corrosion. Qhov sib ntxiv ntawm titanium stabilizes Alloy 825 tiv thaiv rhiab heev nyob rau hauv vuam tej yam kev mob, ua lub alloy resistant rau grain ciam yaig tom qab raug rau kub ntau yam uas yuav sensitize unstabilized stainless hlau. Kev tsim khoom ntawm Alloy 825 yog ib qho ntawm cov nickel-based alloys, thiab cov khoom siv tau yooj yim tsim thiab welded los ntawm ntau yam txuj ci.
incoloy825 General Properties
Incoloy825 alloy (UNS N08825) yog austenitic nickel hlau chromium alloy nrog ntxiv molybdenum, tooj liab thiab titanium. Nws tau raug tsim los muab kev tiv thaiv zoo rau ntau qhov chaw corrosive (oxidizing thiab txo).
Cov ntsiab lus npib tsib xee ntawm Alloy 825 ua rau nws resistant rau chloride kev nyuaj siab corrosion cracking piv rau cov pa austenitic stainless steels, thiab ua ke nrog molybdenum thiab tooj liab, muab kev txhim kho corrosion kuj nyob rau hauv txo ib puag ncig. Cov ntsiab lus chromium thiab molybdenum nyob rau hauv 825 alloy resists chloride ion pitting corrosion thiab resists ntau yam oxidizing atmospheres. Qhov sib ntxiv ntawm titanium ua rau cov hlau tsis hnov tsw hauv lub xeev welded. Qhov kev ruaj khov no tso cai rau Alloy 825 los tiv thaiv intergranular nres tom qab raug rau qhov kub thiab txias uas ib txwm ua rau cov hlau tsis muaj zog.
Incoloy825 alloy muab corrosion kuj nyob rau hauv ntau yam txheej txheem ib puag ncig xws li sulfuric acid, sulfurous acid, phosphoric acid, nitric acid, hydrofluoric acid thiab organic acids, nrog rau alkali (xws li sodium los yog potassium hydroxide) thiab acidic chloride tov.
Kev tsim khoom ntawm incoloy825 alloy yog ib qho ntawm cov nickel-raws li alloys, thiab nws cov ntaub ntawv yooj yim rau kev tsim thiab vuam los ntawm ntau yam txuj ci.
