Duplex Stainless Simbi

Duplex Stainless Simbi Inoreva nezvezvinhu zvine microcenture inoumbwa neFerrite uye Austenite, imwe neimwe account yeanenge 50%. Mukushandiswa chaiko, zvakakodzera kuti chimwe chezvikamu zvekuve pakati pe40-60%.

Maererano nehunhu hwechimiro chezvikamu zviviri-chikamu, nekudzora kurapwa kwemakemikari uye nekuomarara kweDuplex Zvivakwa zvavo zvepanyama zviri pakati peAustenitic Stainless Simbi uye Ferritic Stainless Simbi, asi padyo neFerritic STEL uye Carbon Simbi. Kupikisa ku chloride pomberting uye crevice corrosion yeSuplex Spainless Simbi ine chekuita nezviri zvemukati zvechromium, molybdenum uye nitrogen. Kupikiswa kwayo kurwisa uye crevice corrosion kunogona kufanana neiyo ye136 simbi isina simba, kana yakakwirira kupfuura iyo yesimbi yesimbi, yakadai se6% mo austenitic simbi. All Duplex Stainless Steels yakanyanya kupokana neCloride Shamedza Corrosion Kukanganisa Kupfuura Kupfuura Mbeu, uye Simba ravo zvakare rakanyanya kukwirisa Stains Simbi, uku vachiratidza kupurasitiki kwakanaka uye kuoma.

Zvakanakira Duplex Stainless Simbi

1. Kuenzaniswa neAustenitic Stainless Simbi

1) Simba rakabiwa rinopfuura kaviri iro revanhu vakajairwa neAustenitic Stainless Simbi, uye ine mapurasitiki akakwana uye kuomarara kunodiwa pakugadzira. Iko ukobvu kwematangi ekuchengetedza kana kumanikidzwa kwemidziyo yakagadzirwa neDuplex Stainless Simbi ndeye 30-50% isingashandiswi auterenitic simbi, iyo inokodzera kudzora mari.

2) Iyo ine simba rekunetseka kusimbisa corrosion kupaza, kunyanya munzvimbo dzine chloriz ions. Kunyangwe Duplex Stainless Simbi ine akaderera ezvinyorwa zvine simba rekurwisa kudzvinyirira kukanganisa kupaza kudhirowa pane autenitic simbi. Kushushikana kweCorrosion idambudziko rakatanhamara iro rakajairika austenitic dzimba dzesimbi yakaoma kugadzirisa. 3. Mune mimwe midhiya, senge acetic acid uye yakagadzirirwa acid, inogona kutodzosera yakakwirira-alloy Austenitic simbi uye kunyange afirosi-anopesana nehasha. 4) Iyo ine yakanaka yekuita basa rekudyidzana. Kuenzaniswa neAustenitic Stainless Simbi neiyo Alloy Zvemukati, kupfeka kupokana kweCorrosion uye Corrosion kupokana kuri nani pane Austenitic Stainless Simbi. 5) Iyo Laderar Explansion coefficient yakaderera pane iyo yeAustenitic Stainless Simbi, yakakodzera kubatana neCarbon Simbi, uye ine kukosha kweinjiniya, sekugadzirwa kwemapuranga emanyorero kana kuumbwa.

2.

1) Izvo zvakaringana michina manhamba zvakakwirira kupfuura izvo zvegwenzi risina simba, kunyanya kupurikidzana. Izvo hazvisi sekunzwisisa kune brittleness seya ferritic simbi isina simbi.

2) Kunze kwekunetseka kukanganisa kupesana, kumwe kupokana kwenzvimbo kuri nani pane simbi yesimbi isimbi isina simba.

3.

4) Kubata kwehutachiona kuri nani pane kusimba kwesimbi isina tsvina. Kazhinji, hapana kufungidzira kunodiwa usati waberekerwa uye hapana kurapwa kwekupisa kunodiwa mushure mekutora.

5) Iyo yekushandisa renji yakajeka kupfuura iyo yeiyo ferritic simbi isina simbi.

Application

Nekuda kwesimba rakakwirira reDuplex simbi, rinogona kazhinji kuchengetedza zvigadzirwa, sekudzora gobvu remuti. Tora saf2205 uye saf2507Wiye mimwe mienzaniso. Saf2205 yakakodzera kushandiswa mune yeChrorine-ine nharaunda. Izvi zvinyorwa zvakakodzera kuti mafuta anyatsonatsa kana mamwe maitiro ezvenhau akasanganiswa ne chlorides. Saf2205 inonyanya kukodzera kune yekudziya yekutsinhana iyo inoshandisa chlorine-ine mhinduro dzemvura kana mvura ine munyu ine munyu inotonhora. Izvi zvinyorwa zvakare zvakakwanirwazve kune yakadirwa sulfutic acid mhinduro uye yakachena organic acids uye musanganiswa wavo. Semuenzaniso: mapepa emafuta mumafuta uye egasi indasitiri: Kusvibisa kwemafuta ezvemafuta mumazwi, sarufa-ine gasi kucheneswa kwegesi, marara ekurapa ekurapa ekurapa; kutonhora masisitimu uchishandisa zvishoma mvura ine munyu kana chlorine-ine mhinduro.
