Duplex 2507 mwachidule
Duplex 2507 ndi chitsulo chosapanga dzimbiri cha duplex chopangidwira ntchito zomwe zimafuna mphamvu zapadera komanso kukana dzimbiri. Aloyi 2507 ili ndi 25% chromium, 4% molybdenum, ndi 7% nickel. Kuchuluka kwa molybdenum, chromium ndi nayitrogeni kumapangitsa kuti pakhale kukana kwa chloride pitting ndi corrosion corrosion attack ndipo mawonekedwe a duplex amapereka 2507 kukana kwapadera kwa chloride stress corrosion cracking.
Kugwiritsa ntchito Duplex 2507 kuyenera kungokhala pamapulogalamu ochepera 600 ° F (316 ° C). Kuwonetsa kutentha kowonjezereka kumatha kuchepetsa kulimba komanso kukana kwa dzimbiri kwa aloyi 2507.
Duplex 2507 ili ndi makina abwino kwambiri. Nthawi zambiri choyezera chopepuka cha zinthu 2507 chingagwiritsidwe ntchito kukwaniritsa mphamvu yofananira ya nickel alloy. Zotsatira zake zopulumutsa kulemera zimatha kuchepetsa kwambiri mtengo wonse wa kupanga.
Kukaniza kwa Corrosion
2507 Duplex imalimbana kwambiri ndi dzimbiri limodzi ndi ma organic acid monga formic ndi acetic acid. Imalimbananso kwambiri ndi ma inorganic acid, makamaka ngati ali ndi ma chloride. Aloyi 2507 imagonjetsedwa kwambiri ndi carbide-related intergranular corrosion. Chifukwa cha gawo la ferritic la mawonekedwe a duplex a aloyiyo imalimbana kwambiri ndi kupsinjika kwa dzimbiri pakusweka kwa chloride yotentha yomwe ili ndi malo. Kupyolera mu zowonjezera za chromium, molybdenum ndi dzimbiri za nayitrogeni monga kutsekera ndi kuwononga ming'alu zimatheka. Aloyi 2507 ili ndi kukana kwabwino kwapadziko lonse lapansi.
Kodi mawonekedwe a Duplex 2507 ndi ati?
● High kukana chloride stress dzimbiri akulimbana
● Mphamvu Zapamwamba
● Kulimbana kwambiri ndi chloride pitting ndi ming'alu
● Kusachita dzimbiri bwino
● Zopangira mapulogalamu mpaka 600° F
● Kuchepa kwa kutentha kwa kutentha
● Kuphatikiza kwa katundu woperekedwa ndi austenitic ndi ferritic structure
● Kuwotcherera kwabwino komanso kugwira ntchito
