Pane misiyano yakakura pakati pe duplex Stainless simbi waya mesh 2205 uye 2207 mune zvakawanda zvinhu. Izvi zvinotevera ongororo yakadzama uye pfupiso yekusiyana kwavo:
Kemikari yakagadzirwa uye zvinhu zvemukati:
2205 duplex simbi isina tsvina: kunyanya inoumbwa ne21% chromium, 2.5% molybdenum uye 4.5% nickel-nitrogen alloy. Mukuwedzera, inewo imwe nhamba ye nitrogen (0.14 ~ 0.20%), pamwe chete nehuwandu hwezvinhu zvakadai se carbon, manganese, silicon, phosphorus uye sulfuri.
2207 Duplex Stainless Steel (inozivikanwawo seF53): Iinewo 21% chromium, asi ine molybdenum uye nickel yakakwira kupfuura 2205. Izvo zvakanangana zvinogona kusiyana zvishoma nekuda kwezviyero zvakasiyana kana vagadziri, asi kazhinji iyo molybdenum inokwira uye nickel yemukati zvakare yakakwira.
Performance features:
2205 duplex simbi isina tsvina:
Iine simba rakakwirira uye yakanaka kukanganisa kuoma.
Iyo ine yakanaka yakazara uye yemuno kuramba kushushikana nekuora.
Nekuda kwehuwandu hwehuwandu hwechromium, molybdenum uye nitrogen mumakemikari ayo, ine yakakwira anti-pitting corrosion yakaenzana (PREN kukosha 33-34). Munenge medhiya ese anoora, ayo pitting corrosion resistance uye crevice corrosion resistance zviri nani pane 316L Kana 317L austenitic stainless simbi.
2207 duplex simbi isina tsvina:
Iyo ine zvirinani corrosion resistance uye kupfeka kuramba, kunyanya kurwisa corrosive media senge yakasimba acids, alkalis uye chloride ions.
Iine simba rakakwirira uye kuoma uye yakasimba kudarika simbi yakajairika.
Iyo ine yakanaka plasticity uye processability, pamwe neakanakisa kuomarara uye kuneta kuramba.
Nzvimbo dzekushandisa:
2205 duplex simbi isina tsvina: Inoshandiswa zvakanyanya muindasitiri yemakemikari, indasitiri yemafuta negesi, mainjiniya emugungwa, indasitiri yekuvaka, indasitiri yezvemuchadenga uye mamwe minda. Kuramba kwayo kwakanakisa kwecorrosion kunoita kuti ive sarudzo yakanaka yekugadzira ngarava, mapuratifomu ekumahombekombe nemimwe michina.
2207 duplex simbi isina tsvina: zvakare inokodzera nzvimbo dzinoparadza zvakanyanya, kunyanya munzvimbo dzakaoma senge marine engineering neindasitiri yemakemikari. Nekuda kwemaitiro ayo akasiyana ekuita, inoshandiswawo zvakanyanya muminda yakadai semafuta uye gasi kuchera.
Welding kuita uye mutengo:
2205 duplex simbi isina tsvina ine yakanaka weldability. Izvo hazvidi preheating panguva yewelding kana kupisa kurapwa mushure mekuputika, izvo zvinorerutsa maitiro ekugadzira.
Kusiyana neizvi, kuita kwe2207 duplex stainless simbi kunenge kwakashata uye kunoda maitirwo akasarudzika. Pamusoro pezvo, nekuda kwekuita kwayo kwakanaka, mutengo we2207 duplex stainless steel wakakwira zvakanyanya uye mutengo wekugadzira wakakwira.
