I-UNS S32205 Duplex Stainless Steel

I-UNS S32205 iyibanga eliyi-duplex eline-ferritic-austenitic microstructure. Ingxubevange iqukethe cishe 40-50% ferrite esimweni annealed. I-duplex microstructure inamandla aphezulu wamabanga e-ferritic kuyilapho igcina ukumelana nokugqwala kwamabanga e-austenitic. Akuvamile ukubona insimbi isetshenziswa njengesixazululo esisebenzayo sokuqhekeka kokucindezeleka okubangelwa i-chloride, okuyisithende sika-Achilles sensimbi engagqwali. I-UNS S32205 inokumelana okuphakeme ne-chloride pitting kanye nokugqwala kwe-crevice uma kuqhathaniswa nensimbi engagqwali engu-317L. Ingxubevange inokumelana nokugqwala okuvelele emanzini olwandle kanye nokugxila okuningi kwe-sulfuric acid. Ngaphezu kwalokho, i-UNS S32205 duplex engagqwali futhi imelana ne-sulfide stress corrosion cracking (izindawo zegesi emuncu). Ikhwalithi ephezulu kanye nokusebenza kwe-UNS S32205 kubalwa kabanzi emazingeni aphezulu e-chromium ekhona kanye ne-nitrogen ne-molybdenum.

Izicelo

Izinsimbi ezingenasici ze-Duplex S32205 zivame ukusetshenziswa ku:

Imishini yokukhiqiza i-Chloroethylene, i-methanol synthesis reactor, ezokuthutha nokugcinwa kwe-acetic acid, Ukuhlola nokuthutha uwoyela negesi, imishini yokuqhekeka ye-Catalytic, imishini ye-hydrotreating, izindawo zasolwandle, okokusebenza kokulawula ukungcoliswa kwemvelo, ukukhiqizwa kwe-Pulp & paper, Imboni yokucubungula ukudla, nokuningi.

Ingxubevange S32205 isetshenziswa kakhulu ezimbonini zikawoyela negesi, izimboni zasolwandle, ukucubungula amakhemikhali, nezimboni zenuzi ngenxa yamandla ayo amahle kakhulu kanye nokumelana nokugqwala okuhle. I-LKALLOY ingomunye wabathengisi abahamba phambili be-S32205 ipayipi lensimbi engagqwali, ishubhu, ipuleti, nokufakwa kwamapayipi esixazululweni esilashwayo nesicinyiwe. Imininingwane etholakalayo ye-S32550 yi-ASTM A240, ASTM A479, 1.4507 njalonjalo.
