Ukumelana nokubola
I-329 ine-Pitting Resistance Equivalent (PRE) ye-≥31.
I-329 inokumelana okuhle kakhulu kuxinzelelo lokuqhekeka kwe-corrosion kwindawo yekloridi. Ibakala likwanokumelana kakuhle nokubola ngokubanzi kwimidiya eneasidi, enkosi kumxholo wechromium ephezulu kunye nengxubevange enemolybdenum.
Microstructure
Kwisisombululo esifakwe kunye nesicinyiweyo iSanmac 329 ine-austenitic-ferritic microstructure, ekhululekile kwi-grain-boundary carbides kunye nezigaba ze-intermetallic. Umxholo we-ferrite ngu-55 - 75%.
Ukuchaneka okulungileyo, ukuwelda kunye nokwakheka
I-1.4460 inokwenzeka ukuba idibanise kwaye akufuneki ukuba idityaniswe ngezinto ezisetyenziswayo ze-welding ezifana naleyo yomzali omnye. Intsimbi iya kudityaniswa njengesixhobo se-austenitic kunye negalelo lobushushu eliphantsi kangangoko kunokwenzeka. Ingaba kokubini kubanda- kwaye kushushu kwenziwe. Intsimbi ilula ukwenza umatshini kwaye inobuchule obungcono kakhulu, kodwa i-corrosion resistance kancinane kune-1.4462.
ISIHLOMELO
Amalungu kufuneka afakwe kwisisombululo phakathi kwe-1870/2010ºF (1020/1100ºC) kunye namanzi acinywe. Ngokumalunga nezixa ezilinganayo ze-austenite kunye ne-delta ferrite ziya kwenziwa emva kokuxutywa kwesisombululo.
UKUSEBENZA
Eli bakala linzima kakhulu ukwenza umatshini, mhlawumbi ngaphezulu kunesiqhelo 18/8 austenitics. Uhlobo lwe-309 lune-50 ekhulwini kuphela yesalathiso sobuchule sohlobo lwe-316. Kucetyiswa ukuba kusetyenziswe oomatshini kunye nezixhobo ezifanelekileyo zokwenziwa kweenxalenye ezenziwe kweli bakala.
