Uhlobo lwezintoithubhu yesakhiwo

Izici eziningi eziguquguqukayo zimelela izici zokuguguleka okuphakathi, okuyimikhiqizo yamakhemikhali nokugxila kwayo, izimo zomoya, izinga lokushisa, isikhathi, ngakho-ke uma ungaqondi isimo esiqondile se-medium, ukwenza ukusetshenziswa kwezinto, ukukhetha izinto kunzima.Nokho, le mihlahlandlela elandelayo ingasetshenziswa njengokukhetha:

304 kukho konke ukusetshenziswa kwezinto ezibonakalayo.Emabhilidini ingamelana nokugqwala okuvamile, ingamelana nokucutshungulwa kokudla (okuqukethe i-asidi egxilile kodwa izinga lokushisa eliphezulu nokuqukethwe kwe-chloride kungase kubonakale ukuguguleka), amakhompiyutha ezinto eziphilayo, odayi, kanye nakuzo zonke izinhlobo zezinhlanganisela ezingaphili zingamelana.

I-304L (ikhabhoni ephansi) enokumelana okuhle ne-nitric acid, nezinga lokushisa elihlala isikhathi eside kanye ne-sulfuric acid, esetshenziswa njengoketshezi kulo lonke ithangi legesi, esetshenziselwa imishini ye-cryogenic (304N), yonke imikhiqizo esetshenziswa ngabathengi, izinto zasekhishini, impahla yasesibhedlela, amathuluzi ezokuthutha, izinto zokuphatha amanzi.

I-316 iqukethe i-nickel engaphezu kuka-304, futhi iqukethe u-2%─U-3% we-molybdenum, ukumelana nokugqwala kune-Type 304, uchemile ngokuvuna amaphuzu akhethekile okuguguleka okubangelwa imidiya ye-chloride.I-316 isetshenziswe njengomshini wokuthuthuka we-sulphite pulp, ngoba iyinhlanganisela ye-sulfate ehlala isikhathi eside.Ngaphezu kwalokho, ukusetshenziswa kwayo kuye kwakhuliswa ukuphatha imikhiqizo eminingi yamakhemikhali embonini yokucubungula.

I-317 equkethe u-3% -4% we-molybdenum (izinga eliphezulu kulolu chungechunge nalo liyatholakala), futhi liqukethe izinhlobo ezingaphezu kwezingu-316 ze-chromium, linokumelana okuphezulu kokugqwala komgodi nokusebenza kokugqwala kokuqhekeka.

I-430 ephansi kunokuqukethwe kwe-alloy engu-304, isetshenziswa endaweni efudumele ehlotshiswe ngokusetshenziswa okuphucuziwe kakhulu, ingasetshenziswa futhi i-nitric acid kanye nemishini yokucubungula ukudla.

I-410 inokusetshenziswa okujwayelekile okuthathu kwensimbi engagqwali kokuqukethwe kwe-alloy ephansi kakhulu, udinga amandla nokumelana nokugqwala ngezingxenye ezithwala imithwalo ephezulu ezisetshenzisiwe, njengezingcezu eziqinile.410 emkhathini ofudumele, amanzi, igesi kanye nemikhiqizo yamakhemikhali kwabezindaba eziningi ukumelana nokugqwala okusesilinganisweni.

2205 kune-304 kanye ne-316 ephakeme, ngoba ukwakheka kwepayipi lakhe le-chloride stress stress corrosion cracking linamandla amakhulu okumelana nalo.
