Super Stainless Steel uye nickel-based alloys ndiwo akakosha emhando dzesimbi isina tsvina.Kutanga, inosiyana nemakemikari kubva kune yakajairwa Stainless simbi.Inoreva yakakwira alloy Stainless simbi ine yakakwira nickel, yakakwira chromium, yakakwira molybdenum.
Zvinoenderana neiyo microstructure maitiro emidziyo yesimbi isina tsvina, super stainless simbi yakakamurwa kuita super ferritic simbi isina tsvina, super austenitic simbi isina tsvina, super martensitic simbi isina tsvina, super duplex simbi uye mamwe marudzi.
Super austenitic simbi isina tsvina
Pahwaro hweakajairwa austenitic simbi isina tsvina, nekuvandudza kuchena kwealloy, kuwedzera huwandu hwezvinhu zvinobatsira, kuderedza zvirimo muC, kudzivirira kunaya kweCr23C6 kunokonzerwa ne intergranular corrosion, kuwana yakanaka mechanical zvivakwa, maitiro ezvivakwa uye yemuno corrosion kuramba. , kutsiva Ti yakagadzika simbi isina tsvina.
Super ferritic simbi isina tsvina
Iyo inogara nhaka hunhu hwekusimba kwepamusoro, yakanaka oxidation kuramba uye yakanakisa kushushikana kuomarara kuramba kweyakajairwa ferritic simbi isina tsvina.Panguva imwecheteyo, inovandudza miganhu yeferrite simbi isina tsvina mune welding mamiriro e brittle transition, inonzwa kune intergranular corrosion uye yakaderera kuoma.Ultra-ferritic Stainless simbi ine yakakwira Cr, Mo uye Ultra yakaderera C uye N inogona kuwanikwa nekunatsa tekinoroji, kuderedza zvirimo muC neN, ichiwedzera kudzikamisa uye welding simbi inoomesa zvinhu.Iko kushandiswa kweferritic Stainless simbi mukupokana nekuora uye chloride corrosion resistance yapinda padanho idzva.
Super duplex simbi isina tsvina
Simbi yakagadzirwa mukupera kwema1980.Iwo makuru mabhureki SAF2507, UR52N, Zeron100, nezvimwewo, ayo anoratidzirwa nezvakaderera C zvemukati, yakakwira Mo uye yakakwira N yemukati.Iyo ferritic chikamu chemukati mune simbi account ye40% ~ 45%., ine yakanakisa corrosion resistance.
Super martensitic simbi isina tsvina
Isimbi yakaomeswa isina tsvina ine kuomarara kwakanyanya, kusimba uye kupfeka kuramba, asi kusasimba uye kusimba.Ordinary martensitic Stainless simbi inoshaya ductility yakakwana, inonzwa zvakanyanya kushushikana kana yakaremara, uye yakaoma kuumba mukutonhora kushanda.Nekudzikisa iyo kabhoni yemukati uye nekuwedzera iyo nickel yemukati, super martensitic simbi isina tsvina inogona kuwanikwa.Mumakore achangopfuura, nyika dzakaisa mari yakawanda mukugadzira yakaderera kabhoni uye yakaderera nitrogen super martensitic simbi, uye yakagadzira batch ye super martensitic simbi yezvinangwa zvakasiyana.Super martensitic simbi yakashandiswa zvakanyanya mukushandiswa kwemafuta uye gasi, kuchengetedza uye zvekufambisa zvekushandisa, simba remvura, indasitiri yemakemikari, tembiricha yekugadzira pulp uye mimwe minda.
Inoshanda Stainless simbi
Nekuchinja kwekudiwa kwemusika, zvakasiyana-siyana zvesimbi isina tsvina ine kushandiswa kwakakosha uye mabasa anokosha anoramba achibuda.Zvakadai semutsva wekurapa nickel yemahara austenitic Stainless simbi zvinhu zvakanyanya Cr-Ni austenitic Stainless simbi, ine yakanaka biocompatibility, ine Ni 13% ~ 15%.Nickel imhando ye sensitizing factor, iri teratogenic uye carcinogenic kune zvipenyu.Kushandiswa kwenguva refu kwenickel-ine simbi isina tsvina zvishoma nezvishoma inoparadza uye inobudisa Ni ions.Kana maNi ions akafumiswa mumatishu ari pedyo nekuisirwa, chepfu inogona kukonzereswa uye kuita kwakashata sekuparadza sero uye kuzvimba kunogona kuitika.Cr-Mn-N medical nickel-free austenitic stainless steel yakagadzirwa neInstitute of Metal Research, Chinese Academy of Sciences yakaedzwa kuti ione kugarisana kwehupenyu, uye kushanda kwayo kuri nani kudarika kweCr-Ni austenitic simbi isina tsvina mukushandiswa kwekliniki.Mumwe muenzaniso ndeye antibacterial Stainless simbi.Nekuvandudzwa kwehupenyu hwevanhu, vanhu vanobhadhara zvakanyanya uye zvakanyanya kutarisisa kune zvakatipoteredza uye hutano hwavo, izvo zvinosimudzira kutsvagisa nekuvandudzwa kwezvinhu zvinorwisa mabhakitiriya.Kubva 1980, nyika dzakabudirira dzakamiririrwa neJapan dzakatanga kudzidza nekushandisa antibacterial zvinhu mumidziyo yemumba, kurongedza chikafu, zvinodiwa zvezuva nezuva, midziyo yekugezera uye zvimwe zvinhu.Nissin Steel neKawasaki Steel vakagadzira antibacterial Stainless simbi ine cu uye ag, zvichiteerana.Copper antibacterial simbi isina tsvina inowedzerwa musimbi isina tsvina 0.5% ~ 1.0% mhangura, mushure mekupisa kwakakosha kurapwa, kuitira kuti simbi isina tsvina kubva kumusoro kusvika mukati meyunifomu.Kuparadzira ε-Cu precipitates inoita basa reantibacterial.Iyi mhangura ine antibacterial Stainless simbi inokodzera huwandu hwezvigadzirwa senge premium kitchenware, pamwe nezvimwe zvigadzirwa zvine zvakakwirira zvinodiwa pakugadzirisa zvivakwa uye antibacterial properties.
