  • I-SS904L AISI 904L Intsimbi Engenasici (UNS N08904) 1

I-SS904L AISI 904L Intsimbi Engenasici (UNS N08904)

Inkcazelo emfutshane:

I-UNS NO8904, eyaziwa ngokuba yi-904L, yintsimbi ephantsi ye-carbon high alloy austenitic stainless steel stainless steel stainless steel stainless steel stainless steel stainless steel esetyenziswa kakhulu kwizicelo apho iipropathi zokubola ze-AISI 316L kunye ne-AISI 317L ayanelanga. I-904L inika i-chloride efanelekileyo yoxinzelelo lwe-corrosion ukuchasana nokuqhekeka, ukuchasana kwe-pitting, kunye nokumelana nokubola okuqhelekileyo okungaphezulu kwe-316L kunye ne-317L i-molybdenum ephuculweyo yeentsimbi ezingenasici.

Intshayelelo yeMveliso

I-AISI 904L insimbi engenasici (UNS N08904) yintsimbi ephezulu ye-alloy austenitic. Xa kuthelekiswa ne-316L, i-SS904L inomxholo we-carbon (C) osezantsi, umxholo we-chromium (Cr) ophezulu, kwaye ngokumalunga ne-nickel (Ni) kunye nomxholo we-molybdenum (Mo) ophindwe kabini.316L, eyenza ibe nobushushu obuphezulu bokumelana ne-oxidation, ukumelana ne-pitting, kunye nokumelana nokunciphisa i-asidi (umzekelo, i-asidi ye-sulfuric). I-Nitrojeni (N) inokunciphisa izinga le-chromium carbide precipitation, ngaloo ndlela inciphisa uvakalelo lwe-sensitization, iphinda iphucule ukuxhathisa kwi-pitting kunye ne-crevice corrosion eyenziwa yi-chlorides. Ngokukodwa ukongezwa kwayo kobhedu (Cu) kwenza kube luncedo kuzo zonke izigxina ze-sulfuric acid.

I-alloy 904L yenza ngcono kunezinye iintsimbi ze-austenitic ezingenasici ngenxa ye-alloying ephezulu ye-nickel kunye ne-molybdenum. Ibakala alinamagnetic kuzo zonke iimeko kwaye linokwakheka okugqwesileyo kunye ne-weldability. Isakhiwo se-austenitic sikwanika eli bakala ukuqina okugqwesileyo, kude kube phantsi ukuya kumaqondo okushisa e-cryogenic Umxholo ophezulu we-chromium ukhuthaza kwaye ugcina ifilimu ye-passive ekhusela izinto kwiindawo ezininzi ezinobungozi. Akukho mngcipheko we-intercrystalline corrosion ekupholiseni okanye kwi-welding ngenxa yomxholo wekhabhoni ephantsi. Ubushushu benkonzo yayo bukwi-450°C. Eli bakala liluncedo ngokukhethekileyo kulawulo kunye nezicelo ze-tubing ye-instrumentation apho i-316 kunye ne-317L ayifanelekanga.

I-alloy 904L yaphuhliswa ekuqaleni ukuze imelane neendawo ezine-dilute sulfuric acid. Ikwabonelela ngokuxhathisa okulungileyo kwezinye iiasidi ze-inorganic ezifana ne-asidi ye-phosphoric eshushu kunye neeasidi ezininzi eziphilayo.

I-alloy 904L i-welded ngokulula kwaye iqhutywe ngeendlela eziqhelekileyo zokwenziwa kweevenkile.

I-904L insimbi engenasici (SS904L) isetyenziselwa i-petroleum, ikhemikhali, isichumisi, iinqaba zophuhliso lolwandle, iitanki, imibhobho kunye neetyhubhu kunye nabatshintshisi bokushisa. I-Rolex kunye nabanye abavelisi bewotshi bayayisebenzisa ukwenza iiwotshi
