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

Inkcazo emfutshane:

I-UNS NO8904, eyaziwa kakhulu ngokuba yi-904L, yintsimbi engagqwali ye-austenitic ene-carbon ephezulu esetyenziswa kakhulu kwiindawo apho iipropati zokugqwala ze-AISI 316L kunye ne-AISI 317L zinganeliyo. I-904L inika ukumelana okuhle nokuqhekeka kokugqwala koxinzelelo lwe-chloride, ukumelana nokuqhekeka kwemingxuma, kunye nokumelana ngokubanzi kokugqwala okungaphezulu kwe-316L kunye ne-317L ye-molybdenum ephuculweyo.

Intshayelelo yeMveliso

I-AISI 904L stainless steel (UNS N08904) yintsimbi engagqwali e-austenitic ene-alloy ephezulu. Xa ithelekiswa ne-316L, i-SS904L inomthamo ophantsi we-carbon (C), umxholo ophezulu we-chromium (Cr), kwaye iphantse ibe kabini umxholo we-nickel (Ni) kunye ne-molybdenum (Mo) we316L, nto leyo eyenza ukuba ibe nokumelana okuphezulu kobushushu obuphezulu kwe-oxidation, ukumelana nemingxunya, kunye nokumelana nokunciphisa i-asidi (umz., i-sulfuric acid). I-nitrogen (N) inokunciphisa izinga le-chromium carbide precipitation, ngaloo ndlela inciphise uvakalelo lovakalelo, ikwaphucula ukumelana nemingxunya kunye nokugqwala okubangelwa yi-chloride. Ingakumbi ukongezwa kwayo kwe-copper (Cu) kuyenza ibe luncedo kuzo zonke iindawo ze-sulfuric acid.

I-Alloy 904L isebenza ngcono kunezinye iintsimbi ezingenasici ze-austenitic ngenxa yokuxuba okuphezulu kwe-nickel kunye ne-molybdenum. I-grade ayinamagnethi kuzo zonke iimeko kwaye inokwakheka okuhle kakhulu kunye nokudityaniswa. Isakhiwo se-austenitic sikwanika olu didi ukuqina okugqwesileyo, nokuba kufikelele kumaqondo obushushu abandayo. Umxholo ophezulu we-chromium ukhuthaza kwaye ugcina ifilimu engasebenziyo ekhusela izinto kwiindawo ezininzi ezinobungozi. Akukho mngcipheko wokugqwala kwe-intercrystalline xa kuphola okanye kudityaniswa ngenxa yomxholo ophantsi wekhabhoni. Ubushushu bayo obuphezulu bukwi-450°C. Olu didi luluncedo ngakumbi kwizicelo zolawulo kunye nezixhobo apho i-316 kunye ne-317L zingafanelekanga.

I-Alloy 904L yaqalwa ukuba imelane neendawo ezine-sulfuric acid enyibilikisiweyo. Ikwabonelela ngokumelana okuhle nezinye ii-inorganic acid ezifana ne-hot phosphoric acid kunye nezinye ii-organic acids.

I-alloy 904L idityaniswa kwaye icutshungulwa ngokulula ngokweendlela ezisemgangathweni zokwenza izinto evenkileni.

Intsimbi engagqwaliyo ye-904L (SS904L) isetyenziswa kwi-petroleum, iikhemikhali, izichumisi, iinqaba zophuhliso lolwandle, iitanki, iipayipi kunye neetyhubhu kunye nezixhobo zokutshintsha ubushushu. I-Rolex kunye nabanye abavelisi beewotshi nabo bayayisebenzisa ukwenza iiwotshi.
