I-Super Duplex 2507

I-Duplex 2507 iyi-asuper duplex insimbi engagqwaliyakhelwe izinhlelo zokusebenza ezidinga amandla akhethekile nokumelana nokugqwala. I-alloy 2507 ine-chromium engu-25%, i-molybdenum engu-4%, ne-nickel engu-7%. Lokhu okuqukethwe okuphezulu kwe-molybdenum, i-chromium kanye ne-nitrogen kubangela ukumelana okuhle kakhulu ne-chloride pitting kanye nokuhlaselwa kokugqwala kwe-crevice kanye nesakhiwo esiyi-duplex sinikeza i-2507 ukumelana okuyingqayizivele ekuqhekekeni kwe-chloride stress corrosion.

Ukusetshenziswa kwe-Duplex 2507 kufanele kukhawulelwe ezinhlelweni zokusebenza ezingaphansi kuka-600° F (316° C). Ukuchayeka okunwetshiwe kwezinga lokushisa kunganciphisa kokubili ukuqina nokumelana nokugqwala kwe-alloy 2507.

I-Duplex 2507 inezakhiwo ezinhle kakhulu zemishini. Imvamisa igeji ekhanyayo yento engu-2507 ingasetshenziswa ukuze kuzuzwe amandla okuklama afanayo we-nickel alloy ewugqinsi. Ukonga okuwumphumela wesisindo kunganciphisa kakhulu izindleko eziphelele zokwenziwa.

I-2507 Duplex imelana kakhulu nokugqwala okufanayo ngama-asidi ephilayo afana ne-formic ne-acetic acid. Iphinde imelane kakhulu nama-acids angaphili, ikakhulukazi uma iqukethe ama-chloride. Ingxubevange 2507 imelana kakhulu ne-carbide-intergranular corrosion ehlobene. Ngenxa yengxenye ye-ferritic yesakhiwo esiyi-duplex se-alloy imelana kakhulu nokucindezeleka kokuqhekeka kokugqwala endaweni efudumele equkethe i-chloride. Ngokungezwa kwe-chromium, i-molybdenum ne-nitrogen ukugqwala kwasendaweni okufana ne-pitting kanye nokuhlasela kwemifantu kuyathuthukiswa. I-alloy 2507 inokumelana okuhle kakhulu kwe-pitting yendawo
