Stainless Simbi 904 / 904L

Chigadzirwa Chigadzirwa

Mamwe Mazita Ekutengeserana: Alloy 904L, N08904, W.N 1.4539, N08904, Cr20Ni25Mo4.5Cu

904L ndeye Super Austenstic Stainless Simbi ine yakaderera kabhoni zvemukati. Iyo giredhi inoitirwa kuti ishandiswe pasi pemamiriro ezvinhu akaipisisa. Icho chave chiri application chakaratidzirwa pamusoro pemakore mazhinji uye chakatanga kugadzirirwa kurwisa ngura mune inoderedza sulfuric acid. Iyo yakagadzika uye inogamuchirwa yekumanikidza kushandiswa kwechikepe munyika dzinoverengeka. Nechimiro, 904L yakazara austenitic uye isinganyanye kunaya kunonaya ferrite uye sigma zvikamu pane zvakajairwa austenitic mamaki ane yakakwira molybdenum zvemukati. Hunhu, nekuda kwekusanganiswa kwezvinhu zvine hunyoro hwechromium, nickel, molybdenum nemhangura 904L ine kurwisa kwakanaka kune yakazara ngura, kunyanya mune sulfuric uye phosphoric mamiriro.

Alloy 904L zvigadzirwa mumhando dzeBolts, screws, flanges uye mamwe mafasterners, zvinoenderana nevatengi.

Nei chiwanikwa 904L?

Nemishonga yakanaka pitting ngura uye crevice ngura

High nemishonga kunetseka ngura kutsemuka, intergranular, zvakanaka machinability uye weldability

Mune ese akasiyana marudzi e phosphates904L alloy corrosion kuramba iri pamusoro pane yakajairwa simbi isina simbi.

Mune yakasimba oxidizing nitric acid, ichienzaniswa neakakwira chiwanikwa pasina molybdenum simbi giredhi, 904Lshows yakaderera ngura kuramba.

Iyi chiwanikwa ine kurwisa kuri nani pane yakajairwa simbi isingaite.

Kuderedza ngura mwero mugomba uye makakatanwa nokuda mukuru kugutsikana nickel, uye vane zvakanaka nemishonga kunetseka ngura kutsemuka, munzvimbo yekloride solution, kusangana kwehydroxide solution uye yakafuma hydrogen sulphide.

Chiwanikwa 904L Chikumbiro munda:

Petroleum uye petrochemical michina, senge reactor ye petrochemical michina, nezvimwe.

Sulfuric acid yekuchengetedza uye yekufambisa michina, senge inopisa kupisa, nezvimwe.

Simba chirimwa flue gasi desulfurization devicen, Main zvikamu zvekushandisa: iyo yekumisikidza shongwe muviri, flue, zvemukati zvikamu, pfapfaidzo system, nezvimwe

Organic asidhi scrubber uye fan iri mukugadzirisa system.

Mvura yekurapa mvura, chinodziisa mvura, zvigadzirwa zvekugadzira mapepa, sulfuric acid, nitric acid midziyo, acid,

Mishonga indasitiri nemimwe michina yemakemikari, yekumanikidza mudziyo, zvekushandisa zvekudya.

Mishonga: centrifuge, reactor, nezvimwe.

Dyara chikafu: soy muto muhari, kubika waini, munyu, zvishandiso uye zvipfeko.

Kudzikisa sulphuric acid yakasimba inoparadza simbi simbi 904 l iri kuenderana.
