Stainless simbi imhando yesimbi alloy ine simbi sechimwe chezvikamu zvayo zvikuru, pamwe chete nechromium, nickel, nezvimwe zvinhu.Kuti simbi isina tsvina iine magineti here kana kuti kwete zvinoenderana nekuumbwa kwayo uye nzira yayakagadziriswa nayo.Haasi marudzi ese esimbi asina magineti.Kune magineti uye asiri magineti asina masimbi, zvichienderana nekuumbwa.
Chiisimbi isina ngura?
Simbi isina simbi isimbi isingadziviriri yesimbi, chromium, uye kazhinji zvimwe zvinhu zvakaita senickel, molybdenum, kana manganese.Inonzi "stainless" nokuti inoramba kusvibiswa uye kuora, zvichiita kuti ive sarudzo yakakurumbira kune zvakasiyana-siyana zvekushandisa uko kusimba uye kuramba kune zvakatipoteredza zvakakosha.Simbi isina tsvina inopikisa kusvibisa uye ngura nekuda kwezvinhu zviri mukati: iron, chromium, silicon, kabhoni, nitrogen, uye manganese.Inofanirwa kuumbwa neinosvika 10.5% chromium uye kunyanya 1.2% kabhoni kuti izivikanwe sesimbi isina tsvina.
Mhando dzesimbi isina tsvina
Simbi isina simbi inouya mumhando dzakasiyana kana mamakisi, imwe neimwe iine yayo yakasarudzika maumbirwo uye zvivakwa.Aya mamakisi akaiswa mumapoka makuru mashanu emhuri:
1.Austenitic Stainless Steel (300 Series):Austenitic Stainless simbi ndiyo yakajairika mhando uye inozivikanwa nekusaita magineti zvivakwa, yakanakisa corrosion resistance, uye kuumbwa kwakanaka.
2.Ferritic Stainless Steel (400 Series):Ferritic Stainless simbi ine magineti uye ine yakanaka corrosion resistance, nyangwe isingaite corrosion as austenitic stainless steel.Magiredhi akajairika anosanganisira 430 ne446.
3.Martensitic Stainless Steel (400 Series):Martensitic Stainless simbi zvakare ine magineti uye ine simba rakanaka nekuoma.Inoshandiswa mumashandisirwo apo kupfeka kuramba uye kuoma kwakakosha.Magiredhi akajairwa anosanganisira 410 uye 420.
4.Duplex Stainless Simbi:Duplex Stainless simbi inosanganisa zvivakwa zveese austenitic uye ferritic Stainless simbi.Inopa yakanakisa corrosion resistance uye yakakwirira simba.Magiredhi akajairwa anosanganisira 2205 uye 2507.
5.Kunaya-Kuomesa Stainless Simbi:Kunaya-kuomesa simbi isina tsvina inogona kupiswa-kugadziriswa kuti iwane simba repamusoro uye kuoma.Magiredhi akajairika anosanganisira 17-4 PH uye 15-5 PH.
Chii chinoita magineti simbi isina tsvina?
Simbi isina magineti inogona kunge iri magineti kana isiri-magineti, zvichienderana nekuumbwa kwayo uye microstructure.Stainless simbi yemagineti yesimbi isina tsvina inotsamira pane yayo crystalline chimiro, kuvapo kwealloying zvinhu, uye nhoroondo yayo yekugadzirisa.Austenitic Stainless simbi inowanzova isiri-magnetic, nepo ferritic uye martensitic Stainless simbi dzinowanzoita magineti.Nekudaro, zvakakosha kuti uzive kuti panogona kuve nekusiyana mukati mechikamu chega chega zvichibva pane chaiyo alloy nziyo uye maitiro ekugadzira.
