Umahluko ophambili phakathi kwe-duplex 2205 kunye ne-316 stainless steel uchazwe ngezantsi: 1. Ulwakhiwo: I-Duplex 2205 luhlobo lwentsimbi engagqwaliyo ye-duplex, oluyindibaniselwano yentsimbi engagqwaliyo ye-austenitic kunye nentsimbi engagqwali ye-ferritic. IqulatheUmahluko ophambili phakathi kwentsimbi engagqwali ye-duplex 2205 kunye ne-316 uchazwe ngezantsi: 1. Ulwakhiwo: I-Duplex 2205 luhlobo lwentsimbi engagqwali ye-duplex, oluyindibaniselwano yentsimbi engagqwali ye-austenitic kunye nentsimbi engagqwali ye-ferritic. Iqulathe malunga ne-22% ye-chromium, i-5% ye-nickel, i-3% ye-molybdenum kunye ne-4.5% ye-nitrogen. Kwelinye icala, i-316 stainless steel yi-alloy yentsimbi engagqwali ye-austenitic equlathe malunga ne-16-18% ye-chromium, i-10-14% ye-nickel, i-2-3% ye-molybdenum, kunye nezinye izinto ezincinci ezifana ne-carbon, i-manganese, kunye ne-silicon. 2. Ukumelana nokugqwala: Xa kuthelekiswa nentsimbi engagqwaliyo engama-316, i-duplex 2205 inokumelana nokugqwala okungcono, ngakumbi kwindawo etyebileyo kwi-chloride. Inokumelana okuphezulu kwi-pitting, ukugqwala kwe-crevice kunye nokuqhekeka kwe-stress corrosion. Oku kwenza i-duplex steel 2205 ifaneleke kakhulu kwizicelo zaselwandle, ioyile kunye negesi, kunye namashishini eekhemikhali. I-316 stainless steel ikwabonakalisa ukumelana nokugqwala okuhle, kodwa isenokungasebenzi njenge-duplex 2205 kwiindawo ze-chloride. 3. Amandla: Amandla e-duplex 2205 aphezulu kunalawo e-316 stainless steel. Ulwakhiwo lwayo lwe-biphasic lunegalelo kwiimpawu zayo ezintle zoomatshini, ezifana namandla aphezulu okutsalwa kunye nokukhupha. Olu ncedo lokuqina lwenza i-duplex 2205 ifaneleke kwizicelo ezifuna amandla aphezulu kunye nokuthembeka. 4. Ixabiso: I-Duplex 2205 ngokubanzi ibiza kakhulu kune-316 stainless steel ngenxa yeendleko eziphezulu zezinto kunye nenkqubo yokuvelisa enzima. Ukongezwa kwezinto ezixutywayo ezifana ne-nitrogen kunye ne-molybdenum kwandisa iindleko zemveliso. Nangona kunjalo, umahluko wamaxabiso unokwahluka ngokusekelwe kwiimeko zemarike kunye nezinye izinto. Ngamafutshane, xa kuthelekiswa nentsimbi engagqwaliyo engama-316, i-duplex 2205 inokumelana nokugqwala okugqwesileyo, amandla aphezulu kunye nokudityaniswa okuhle. Nangona kunjalo, ukhetho phakathi kwezi zimbini luya kuxhomekeka kwiimfuno ezithile zesicelo kunye nokuqwalaselwa kwebhajethi malunga ne-22% ye-chromium, i-5% ye-nickel, i-3% ye-molybdenum kunye ne-4.5% ye-nitrogen. Kwelinye icala, i-316 stainless steel yi-alloy yentsimbi engagqwaliyo e-austenitic equlathe malunga ne-16-18% ye-chromium, i-10-14% ye-nickel, i-2-3% ye-molybdenum, kunye nezixa ezincinci zezinye izinto ezifana ne-carbon, i-manganese, kunye ne-silicon. 2.

Inokumelana okuphezulu kwi-pitting, ukugqwala kwe-crevice kunye nokuqhekeka kwe-stress corrosion. Oku kwenza i-duplex steel 2205 ilungele ukusetyenziswa kumashishini olwandle, eoyile kunye negesi, kunye neekhemikhali. Intsimbi engagqwaliyo engu-316 ikwabonakalisa ukumelana nokugqwala okuhle, kodwa isenokungasebenzi njenge-duplex 2205 kwiindawo ze-chloride. 3. Amandla: Amandla e-duplex 2205 aphezulu kune-316 stainless steel. Ulwakhiwo lwayo lwe-biphasic lunegalelo kwiimpawu zayo ezintle zoomatshini, ezifana namandla aphezulu okutsalwa kunye nokukhupha. Olu ncedo lokuqina lwenza i-duplex 2205 ifaneleke kwizicelo ezifuna amandla aphezulu kunye nokuthembeka. 4.
