Incazelo:

I-S32750 (2507, F53, 1.4410) i-super duplex insimbi engagqwali iqukethe 25% chromium, 4% molybdenum kanye 7% nickel.
Insimbi ye-S32750 enezigaba ezimbili inamandla aqinile nokumelana nokugqwala, esetshenziswa kakhulu ekucubunguleni amakhemikhali, embonini ye-petrochemical kanye nemishini yangaphansi kolwandle.
Insimbi ye-S32750 yesigaba esikabili inokumelana okuqinile nokugqwala kwe-chloride, ukuhanjiswa okuphezulu kwe-thermal kanye ne-coefficient ephansi yokwandisa okushisayo.
Okuqukethwe okuphezulu kwe-chromium, i-molybdenum ne-nitrogen inokumelana okuphezulu nokugqwala kwamabala, ukugqwala nokugqwala okuvamile.
Insimbi ye-S32750 enezigaba ezimbili nayo inamandla omthelela aphezulu futhi ayifanele ukusetshenziswa emazingeni okushisa angaphezu kuka-570 ° c, lapho ukuqina kwayo kuncipha ngokuhamba kwesikhathi.
I-S32750 i-dual phase steel ihlanganise insimbi eminingi ye-ferritic kanye nensimbi ye-austenitic iyimpahla ezuzisa kakhulu, ngoba i-chromium yensimbi ne-molybdenum iphakeme kakhulu, ngakho-ke inokumelana okuhle kakhulu nokugqwala, ukugqwala kwe-crevice kanye nekhono lokugqwala okufanayo, i-duplex microstructure iqinisekisa ukuthi insimbi inekhono lokumelana okuphezulu nokucindezeleka kokuqhekeka kokugqwala, futhi amandla emishini aphakeme.

1. Uma kuqhathaniswa ne-904L, insimbi ye-S32750 enezigaba ezimbili inokumelana nokugqwala okuqinile ukuze ihlambulule i-sulfuric acid exutshwe nama-ion e-chloride.
I-904L iyingxubevange ye-austenitic eklanyelwe ngokukhethekile ukumelana nokugqwala kwe-sulfuric acid emsulwa.
Okuqukethwe okuphezulu kwe-chromium ne-molybdenum ye-S32750 yensimbi enezigaba ezimbili kuyenza imelane kakhulu nokugqwala sekukonke kwama-asidi ephilayo njenge-asidi ne-acetic acid.
Insimbi eyi-duplex ye-S32750 nayo inokumelana nokugqwala okuqinile kuma-asidi angaphili, ikakhulukazi lawo aqukethe ama-chloride.
I-Grade 316L ayikwazi ukusetshenziswa ezindaweni ezine-hydrochloric acid lapho ingase ibhekane nokugqwala kwendawo noma emhlabeni jikelele.
I-S32750 insimbi yesigaba esimbaxambili ingasetshenziswa endaweni ye-dilute hydrochloric acid, enokumelana okuqinile nokulimala kwamabala kanye nekhono lokugqwala.
2. I-Intercrystalline corrosion S32750 insimbi yesigaba esikabili inokuqukethwe kwekhabhoni ephansi, okwehlisa kakhulu ubungozi bemvula ye-intercrystalline carbide phakathi nokwelashwa kokushisa.Ngakho-ke, le alloy imelana kakhulu ne-carbon-related intercrystalline corrosion.
3. Ukucindezeleka kwe-corrosion cracking: ngenxa yokuqukethwe kwayo okuphezulu kwe-alloy, ukumelana nokugqwala namandla ensimbi ye-S32750 ye-dual-phase steel kungcono kunaleyo ye-2205.
I-S32750 dual - isakhiwo esiyinhlanganisela yensimbi yesigaba siyenza imelane nengcindezi yokuqhekeka kokugqwala.
I-4, ukugqwala nokugqwala: kunezindlela eziningi zokuhlola ukumelana nokugqwala kwemikhiqizo yensimbi esixazululweni esiqukethe i-chloride.Izinga lokushisa elibalulekile lokugqwala kanye nokugqwala kwensimbi engagqwali esebenza kahle kakhulu kusixazululo se-sodium chloride esingu-1M kucacisiwe.
Imiphumela yokuhlola eyahlukahlukene ibonisa ukuthi i-S32750 dual - phase steel inokumelana nokugqwala okuhle kakhulu.
I-5, i-crack corrosion: imifantu esakhiweni nezinye izici cishe ayinakugwenywa, okwenza insimbi engagqwali ibe sengozini yokugqwala endaweni ye-chloride.I-2507 dual - phase steel inekhono eliqinile lokulwa nokubola.
