I-Super Duplex stainless njenge-S32750, iyingxubevange yezakhiwo ezincane ze-austenite ne-ferrite (50/50) enamandla athuthukisiwe ngaphezu kwamazinga ensimbi e-ferritic ne-austenitic. Umehluko omkhulu ukuthi i-Super Duplex inokuqukethwe okuphezulu kwe-molybdenum ne-chromium okunikeza into leyo amandla amakhulu. I-chromium ephezulu futhi ikhuthaza ukwakheka kwezigaba eziyingozi ze-intermetallic, ezinomuzwa wokuqina nge-475°C ngenxa yokuncipha kwesigaba se-α’ esicebile nge-chromium, kanye nokuqina nge-sigma, chi nezinye izigaba emazingeni okushisa aphezulu.

I-Alloy 2507 (S32750) nayo inokuqukethwe okuphezulu kwe-nitrogen, okungagcini nje ngokukhuthaza ukwakheka kwe-austenite nokwandisa amandla, kodwa futhi kubambezela ukwakheka kwezigaba ze-intermetallic ngokwanele ukuvumela ukucutshungulwa nokwenziwa kwezinga le-duplex.

Leli zinga libonakala ngokumelana ne-chloride corrosion okuhle kakhulu, kuhlanganiswe namandla emishini aphezulu kakhulu. Likulungele kakhulu ukusetshenziswa ezindaweni ezinobudlova njengamanzi olwandle afudumele ane-chloride nezinto ezine-asidi eziqukethe i-chloride.

Izici ze-Alloy 2507 (S32750) zimi kanje:

● Ukumelana okuhle kakhulu nokuqhekeka kwe-stress corrosion cracking (SCC) ezindaweni eziqukethe i-chloride
● Ukumelana okuhle kakhulu nokugqwala kwemingodi nokugqwala kwe-crevice
● Ukumelana okuphezulu nokugqwala okujwayelekile
● Amandla emishini aphezulu kakhulu
● Izakhiwo zomzimba ezinikeza izinzuzo zokuklama
● Ukumelana okuphezulu nokugqwala kokuguguleka nokukhathala kokugqwala
● Ukushiswa okuhle

I-S32750 yakhelwe izinhlelo ezidinga amandla aphakeme nokumelana nokugqwala, okutholakala ku-inqubo yamakhemikhali, imishini yamafutha kanye nempahla yamanzi olwandle. Isetshenziswa kakhulu ekuhloleni/ukukhiqiza amafutha ngezansi kolwandle kanye nasekushintshaniseni ukushisa ekucubunguleni amakhemikhali. Lolu hlobo lufaneleka futhi ezinhlelweni zokucindezela kanye nezinsimbi ezindaweni ezishisayo zasolwandle.
