I-321 insimbi engenasici 4.0 * 0.35 mm ityhubhu edibeneyo
I-321 yi-titanium ezinzileyo ye-chromium-nickel austenitic steel stainless enamandla kunye nokumelana nokugqwesa okugqwesileyo, njengoko kubonelelwe kwimeko ye-anneal kunye nobunzima obuqhelekileyo be-brinell ye-175. Ibonakaliswe ngokuxhathisa okuphezulu kwe-corrosion ngokubanzi kwiindawo ezidliwayo ze-atmospheric kwiindawo ezininzi ezibonisa ukuxhathisa oxidi ii-agent, ukutya okuqhelekileyo, izisombululo zokucoca, idayi, uninzi lweekhemikhali eziphilayo kunye neentlobo ngeentlobo zeekhemikhali ezingaphiliyo, kunye neegesi ezishushu zepetroleum, iigesi zokutsha komphunga, i-nitric acid, kunye nomlinganiselo omncinci we-asidi yesulfuric.Ibonisa ukuxhathisa okulungileyo kwi-oxidation kumaqondo obushushu aphakamileyo inokumelana okubalaseleyo kwi-intergranular corrosion kwaye inokuqina okugqwesileyo.I-321 ayinakwenziwa lukhuni ngonyango lwe-thermal, kodwa amandla kunye nobulukhuni bunokwandiswa kakhulu ngokusebenza okubandayo, kunye nokunciphisa okulandelayo kwi-ductility.
Isetyenziswe ngokubanzi kwizicelo apho ukongezwa kwe-titanium kunye nefuthe layo lokuzinzisa njengento yokwenza i-carbide ivumela ukuba idityaniswe kunye / okanye isetyenziswe ngaphakathi kwi-carbide precipitation range 430.oC - 870oC ngaphandle komngcipheko we-intergranular corrosion.Ezi ziquka ukuLungiswa kokuTya, Izixhobo zobisi, iKhemikhali, i-Petrochemical, iThutho kunye namashishini ahambelanayo njl.
Isixhobo esingenazibuthe esikwimeko evalelweyo, kodwa sinokuba yimagnethi epholileyo emva kokubanda kakhulu.
I-anealing iyafuneka ukuze kulungiswe xa kukho imfuneko.
QAPHELA Elona nqanaba liphezulu lokumelana nomhlwa liphunyeziwe kwimeko yokuvalelwa.
