Nakuba i-Duplex 2205 iwumkhiqizo ovame kakhulu we-duplex esiwunikezayo, singaletha i-Duplex 2304 ne-Duplex 2207 enezikhathi zokuhola ezincishisiwe njengoba lawa ma-alloys egcwele. I-alloy 2205 (UNS S32305/S31803) iyi-chromium engu-22%, i-molybdenum engu-3%, i-nickel engu-5-6%, ipayipi le-nitrogen alloyed duplex stainless steel elinezimfanelo ezijwayelekile ezijwayelekile, ezasendaweni, kanye nezakhiwo zokumelana nokugqwala kwengcindezi ngaphezu kwamandla aphezulu kanye nokuqina komthelela omuhle kakhulu.

Inhlanganisela yamandla aphezulu, ukumelana nokugqwala kanye nokushisela okusesilinganisweni kunezinzuzo eziningi kodwa futhi kuletha ukuntula nokulinganiselwa. Amandla aphezulu ayingozi uma kwenziwa futhi kwenziwa imishini. Amandla aphezulu abuye asho ukuthi insimbi ine-ductile encane kunamamaki e-austenitic. Lokhu kusho ukuthi lezi zinsimbi azilungile uma izimpahla ezikhiqizwayo zidinga noma yiliphi izinga lokubunjwa okuyinkimbinkimbi. Kuyafaneleka futhi ukukhumbula ukuthi i-evemn uma into ingakhiwa nge-duplex steel amandla amakhulu ayadingeka. I-metalurgy ye-duplex stainless steels iyinkimbinkimbi kakhulu kune-austenitic noma izinsimbi ze-ferritic okuholela ekutheni ziyinkimbinkimbi futhi ngenxa yalokho zibiza kakhulu ukuzikhiqiza. Kodwa-ke inani eliphansi le-nickel kuzo uma liqhathaniswa namamaki e-austenitic liyasiza ekugcineni izindleko ziphansi futhi zehlise ukuguquguquka kwentengo.

2205 insimbi engagqwali eyi-duplex iyikhambi elibiza izindleko ezinhlelweni eziningi lapho uchungechunge lwama-stainless steels angama-300 lusengozini yokuqhekeka kokugqwala kokucindezeleka kwe-chloride. Ukuqhekeka kokugqwala kwengcindezi kwenzeka lapho izinsimbi ezingenasici zingaphansi kwengcindezi eqinile, ngenkathi zithinta izixazululo eziqukethe ama-chloride. Ukwenyuka kwamazinga okushisa nakho kukhulisa ukuthambekela kwezinsimbi ezingenasici ukuze kugcizelele ukuqhekeka kokugqwala.

Amapayipi ensimbi ye-alloy kanye namashubhu kuyisinqumo esingcono kakhulu sokuqhekeka kwe-stress corrosion cracking (SSC). Lokhu kusebenza nasezindaweni lapho inkinga ingumgodi kanye nokugqwala kwemifantu. Lawa mashubhu namashubhu atholakala ngaphakathi kwezibonelelo zomshini kanye nokubekezelelana.

Inhlanganisela ye-chromium, i-molybdenum ne-nitrogen idlulisa ukumelana okuhle kwe-2205 ku-chloride pitting kanye nokugqwala kwe-crevice. Lokhu kumelana kubaluleke kakhulu ezinsizeni ezifana nezindawo zasolwandle, amanzi anosawoti, ukusebenza kwe-bleaching, amasistimu amanzi avaliwe kanye nezinye izinhlelo zokusebenza zokucubungula ukudla. I-chromium ephezulu, i-molybdenum ne-nitrogen okuqukethwe kuka-2205 kunikeza ukumelana nokugqwala okuphakeme kunezinsimbi ezingenasici ezivamile, njengokuthi, 316L kanye no-317L ezindaweni eziningi.

I-dual phase steel \/ super duplex steel stainless steel pipe iwuhlobo lwensimbi engagqwali enamandla amakhulu nokumelana nokugqwala okuphezulu, okunezici zensimbi engagqwali ye-austenitic kanye nensimbi engagqwali ye-ferritic. Ngokuvamile, lapho okuqukethwe kwekhabhoni kuphansi, okuqukethwe kwe-Cr kungu-18% ~ 28%, futhi okuqukethwe kwe-Ni kungu-3% ~ 10%. Ezinye izinsimbi nazo ziqukethe i-Mo, Cu, Nb, Ti, N nezinye izakhi ze-alloy.

Ipayipi le-chrome A335 P1 lidumile ezimbonini eziningana. Lokhu kubonakala ikakhulukazi embonini yamandla nasezimbonini ze-petrochemical, lapho lawa mapayipi ensimbi asekelwe ku-ASME SA 335 P1 grade grade alloy avame ukusetshenziswa ezindaweni ezihluza uwoyela.
