Kakaretso ea Duplex 2507

Duplex 2507 ke tšepe e sa hloekang ea duplex e etselitsoeng lits'ebetso tse hlokang matla a ikhethang le ho hanyetsa kutu. Alloy 2507 e na le 25% chromium, 4% molybdenum, le 7% nickel. Boemo bona bo phahameng ba molybdenum, chromium le naetrojene bo etsa hore ho be le khanyetso e ntle ea chloride pitting le crevice corrosion attack le sebopeho sa duplex se fana ka 2507 ka mokhoa o ikhethang oa ho hanyetsa chloride stress corrosion cracking.

Tšebeliso ea Duplex 2507 e lokela ho lekanyetsoa lits'ebetsong tse ka tlase ho 600 ° F (316 ° C). Ho pepeseha ha mocheso o phahameng ho ka fokotsa ho tiea le ho hanyetsa ha kutu ea alloy 2507.

Duplex 2507 e na le thepa e ntle ea mochini. Hangata gauge e bobebe ea lisebelisoa tsa 2507 e ka sebelisoa ho fihlela matla a tšoanang a moralo oa alloy e teteaneng ea nickel. Ho boloka boima ba 'mele ho ka fokotsa haholo litšenyehelo tse akaretsang tsa ho etsa thepa.

Khanyetso ea Corrosion

2507 Duplex e hanana haholo le kutu e ts'oanang ka li-organic acid tse kang formic le acetic acid. E boetse e hanyetsana haholo le li-inorganic acid, haholo-holo haeba li na le chloride. Alloy 2507 e hanyetsana haholo le corrosion e amanang le carbide intergranular. Ka lebaka la karolo ea ferritic ea sebopeho sa duplex ea alloy e hanyetsana haholo le khatello ea maikutlo ea ho phatloha ha chloride e futhumetseng e nang le tikoloho. Ka tlatsetso ea chromium, molybdenum le nitrogen localized corrosion joalo ka pitting le tlhaselo ea maphao lia ntlafatsoa. Alloy 2507 e na le khanyetso e ntle ea libaka tsa lehae.
