1. Chizvarwa chechipiri chemapaipi esimbi isina tsvina ine duplex chine hunhu hwekabhoni yakaderera zvakanyanya, nitrogen yakaderera, chimiro chakajairika Cr5% Ni0.17%n uye nitrogen yakakwira 2205 kupfuura chizvarwa chekutanga chemapaipi esimbi isina tsvina ine duplex, izvo zvinovandudza kuramba kusimba kwekutumbuka uye kuramba kupinza kweacidic media ine chloride ion yakawanda. Nitrogen chinhu chakasimba chinoumba austenite. Kuwedzera nitrogen muduplex stainless steel hakungogadzirisi chete plasticity uye kusimba kwesimbi pasina kukuvara kuri pachena, asiwo kunovandudza simba resimbi, uye kunodzivisa kunaya kwemvura nekunonoka kwemacarbides.
2. Basa rehurongwa: Mugreenhouse, austenite neferrite zvinoumba inenge hafu yemhinduro yakasimba, ine hunhu hwechimiro chebiphase. Inoramba iine hunhu hwehuwandu hushoma hwemaconductor esimbi isina ngura yeferritic, kuramba maburi, kutsemuka uye chloride stress corrosion, ine kusimba kwakanaka, tembiricha yakaderera yekupwanya, kuramba ngura pakati pegranular uye hunhu hwemakanika uye kugona kusveta zvakanaka.
3. Pasi pemamiriro akafanana ekumanikidzwa anogona kuchengetedza zvinhu, simba remugoho uye kuramba ngura kwepombi yesimbi isina tsvina yesimbi mbiri (duplex steel stainless steel) kunenge ka1 pane simbi isina tsvina yeaustenitic, coefficient yekuwedzera kwemutsara yakaderera pane simbi isina tsvina yeaustenitic yesimbi isina tsvina yeaustenitic, uye simbi ine kabhoni shoma iri pedyo nayo. Kugadzira kwechando hakuna kunaka sesimbi isina tsvina yeaustenitic.
4. Kugona Kupinza: pombi yesimbi isina tsvina 2205 ine kugona kupinza zvakanaka, kupinza kunotonhora, kupisa kushoma, kazhinji hapana kupisa usati wapinza, hapana kurapwa kwekupisa mushure mekupinza. Nekuda kwekusakwana kweferrite imwe chete uye huwandu hwakawanda hwenitrogen munzvimbo ine kupisa, simba rewaya yekupinza rinogona kudzorwa panguva ino kana zvinhu zvekupinza zvasarudzwa zvine musoro, uye kushanda kwakazara kwakanaka.
5. Kupisa: Kunzwa kwekupisa kwakaderera zvikuru pane kwesimbi isingatsvinda ye austenitic. Izvi zvinokonzerwa nekuti nickel haina kukwira, tsvina iri nyore kugadzira eutectic inonyunguduka yakaderera, firimu remvura rine poindi shoma yekunyunguduka harisi nyore kugadzira, uye kukura nekukurumidza kwengozi yezviyo hakupo kana tembiricha yakakwira.
6. Kuoma kwenzvimbo ine kupisa: Dambudziko guru rekunamira pombi dzesimbi dzisina tsvina dzesimbi mbiri nderenzvimbo ine kupisa. Nekuda kwekutonhora nekukurumidza kwenzvimbo ine kupisa mumamiriro asina kuenzana ekupisa kwe welding, ferrite yakawanda inotonhodzwa inogara ichichengetwa, izvo zvinowanzowedzera kunzwa kwekuora uye kutsemuka kunokonzerwa nehydrogen.
7. Kugadzira simbi dzesimbi dzeWelding: Munguva yekushongedza simbi dze ...
