1. Chizvarwa chechipiri cheduplex steel stainless simbi pombi ine hunhu hwe Ultra-low kabhoni, yakaderera nitrogen, yakajairika kuumbwa Cr5% Ni0.17%n uye 2205 yakakwirira nitrogen yemukati kupfuura yekutanga chizvarwa che duplex simbi isina tsvina pombi, iyo inovandudza. kupikisa kusagadzikana kwekuora uye pitting kuramba kweacidic media ine yakakwira chloride ion concentration.Nitrogen chinhu chakasimba che austenite kugadzira chinhu.Kuwedzerwa kwe nitrogen mu duplex simbi isina tsvina haingogadzirisi plastiki uye kuoma kwesimbi pasina kukuvara kuri pachena, asiwo inovandudza simba resimbi, uye inodzivisa kunaya uye kunonoka kwecarbides.
2. Kushanda kwesangano: Mune greenhouse, austenite uye ferrite account inenge hafu yemhinduro yakasimba, iyo ine maitiro e biphase structure.Iyo inochengetedza hunhu hushoma hwehuwandu hweferritic simbi isina simbi conductors, kuramba kugomba, kuputika uye chloride kusagadzikana ngura, nekuomarara kwakanaka, yakaderera embrittlement tembiricha, kuramba kune intergranular corrosion uye michina zvinhu uye yakanaka weldability.
3. Pasi pemamiriro akafanana ekumanikidza giredhi anogona kuchengetedza zvinhu, iyo goho simba uye kushushikana corrosion resistance ye duplex steel stainless simbi pombi inenge 1 nguva iyo yeaustenitic stainless simbi, mutsara wekuwedzera coefficient ishoma pane austenitic stainless simbi ye austenitic stainless. simbi system, uye yakaderera kabhoni simbi iri pedyo nayo.Cold forging haina kunaka seaustenitic stainless simbi.
4. Weldability: duplex simbi Stainless simbi pombi 2205 ane zvakanaka weldability, welding kutonhora, inopisa crack senitivity iduku, kazhinji hapana preheating pamberi welding, hapana kupisa kurapwa pashure welding.Nekuda kwemaitiro madiki e-single-phase ferrite uye yakakwira nitrogen yemukati munzvimbo inopisa yakakanganiswa, iyo welding waya simba inogona kudzorwa panguva ino kana welding zvinhu zvasarudzwa zvine musoro, uye kushanda kwakazara kwakanaka.
5. Kupisa kunopisa: Kunzwisiswa kwekupisa kunopisa kwakaderera zvikuru kupfuura ye austenitic stainless steel.Izvi zvinodaro nekuti iyo nickel yemukati haina kukwirira, tsvina iyo iri nyore kuumba yakaderera-kunyungudika eutectic yakaderera, iyo yemvura firimu ine yakaderera kunyungudika haisi nyore kugadzira, uye kukurumidza kukura kwengozi yezviyo haipo pakakwirira. tembiricha.
6. Brittleness yekupisa yakakanganisika nzvimbo: Dambudziko guru rewelding ye duplex simbi Stainless simbi pombi ndiyo inopisa inokanganisa nzvimbo.Nekuda kwekukurumidza kutonhora kunokonzerwa nekupisa kwakakanganisika nzvimbo munzvimbo isina kuenzana yewelding kupisa kutenderera, yakawanda yakatonhodzwa ferrite inogara ichichengetwa, izvo zvinowanzoita kuwedzera kunzwisisika kwekuora uye hydrogen-induced cracking.
7. Welding metallurgy: Munguva yewelding process ye duplex Stainless steel, pasi pechiito chekupisa bhasikoro, iyo microstructure uye inopisa-yakakanganiswa nzvimbo ye weld metal yakave yakatevedzana shanduko.Pakupisa kwepamusoro, iyo microstructure ye duplex simbi isina tsvina inoputirwa neferrite uye austenite panguva yekutonhora.Huwandu hwekunaya kweaustenite hunokonzerwa nezvinhu zvakawanda.
