Izinto ezibonakalayo ze-S32760
I-S32760 (F55), i-X2CrNiMoCuWN 25.7.4, i-German standard 1.4501, amandla aqinile nokumelana nokugqwala, okusetshenziselwa ikakhulukazi ukucubungula kwamakhemikhali, imishini ye-petrochemical kanye ne-subsea.Inokumelana okuqinile nokugqwala kwe-chloride, ukuhanjiswa okuphezulu kwe-thermal kanye ne-coefficient ephansi yokwandisa okushisayo.I-chromium ephakeme, i-molybdenum kanye ne-nitrogen, inokumelana okuphezulu ne-pitting, ukugqwala kwemifantu kanye nokugqwala okuvamile.
I-alloy S32760 iyinsimbi engagqwali eyi-duplex ephezulu ehlinzekwe endaweni eshisayo esetshenziselwe futhi enesixazululo.Njengensimbi engagqwali eyi-duplex ephezulu, ihlanganisa izici ezifiselekayo zezinsimbi ze-austenitic ne-ferritic.I-chromium ephakeme, i-molybdenum ne-nitrogen okuqukethwe kuphumela ku-Pitting Resistance Equivalent Number (PREN) > 40, ehlinzeka ngamakhono aphakeme wokugqwala nokugqwala phezu kwezinsimbi ezingenasici ze-austenitic kanye ne-duplex cishe kuyo yonke imidiya ebolayo, kanye nezinga lokushisa elibalulekile le-pitting Isexwayiso esingaphezu kuka-50°C.Inguqulo yefomula ye-PREN iphinda ifake okuthi W njengomphumela omuhle ekumelaneni nokugoba kukonke.
Inikeza amandla aphakeme kune-austenitic kanye ne-22% ye-Cr duplex stainless steels futhi ifakwe ohlwini lwe-NACE MR 0175 ngesevisi emuncu kanye ne-ASME yezinhlelo zokusebenza zemikhumbi yokucindezela.

I-S32760 Material Application Areas
I-S32760 iwuhlobo lwamandla aphezulu kanye nokumelana nokugqwala, okusetshenziselwa ikakhulukazi ukucubungula amakhemikhali, imishini ye-petrochemical kanye ne-subsea.Izindawo zokufaka isicelo: Imishini yemboni kawoyela negesi Amapulatifomu asogwini, izinto ezishintsha ukushisa, izinto ezisebenza ngaphansi kwamanzi, izinto zokulwa nomlilo Imboni yokucubungula amakhemikhali, imboni yomkhumbi kanye namapayipi Izitshalo zokukhipha usawoti emanzini, izitshalo ze-RO ezinengcindezi ephezulu kanye namapayipi ahamba ngaphansi kolwandle Izingxenye zemishini, amandla aphezulu, izingxenye zokulwa nokugqwala.
