304 uye 316 ese ari maviri makodhi esimbi isina tsvina.Muchidimbu, havana kusiyana.Iwo ese ari maviri simbi isina tsvina, asi ndeemhando dzakasiyana kana akapatsanurwa.Hunhu hwe316 simbi isina simbi yakakwirira kupfuura iyo ye304 simbi isina tsvina.Pahwaro hwe304,316 simbi isina tsvinainosanganisa simbi molybdenum, iyo inogona kuwedzera kusimbisa chimiro chemolecular yesimbi isina tsvina.Ita kuti iwedzere kupfeka-kusagadzikana uye anti-oxidation, uye panguva imwecheteyo, iyo corrosion resistance inowedzerwawo zvakanyanya.
Kuenzanisa kwekuita kwe304L uye316L yakatsvaira Stainless Steel Plate
Kudzivirirwa kwekuora kwesimbi isina simbi kwakakosha zvakanyanya kupfuura yayo pachayo kuramba.Semusanganiswa, yekutanga kuumbwa kwesimbi isina tsvina isimbi, asi nekuda kwekuwedzera kwezvimwe zvinhu, inogona kuwana akawanda anodiwa ekushandisa zvivakwa.Chromium ndiyo inogadzirisa chinhu musimbi isina tsvina, inokwana 10.5% yekuumbwa.Zvimwe zvinosanganisa zvinhu zvinosanganisira nickel, titanium, mhangura, nitrogen uye selenium.
Musiyano uripo pakati pe304L ne316L brushed Stainless Steel Plate ndiko kuvapo kwechromium, 316L yakabhurashwa simbi isina ngura ine zvirinani kusaita ngura, kunyanya munzvimbo yepakati nemunyu wakanyanya.Zvekushandisa zvine zvigadzirwa zvekunze zvesimbi isina simbi, Stainless simbi yakanaka inodzivirira corrosion zvinhu zvekuratidzwa kunze kwenguva refu.
natural corrosion resistance
Zvakasiyana zviri mukati mechromium uye zvimwe zvinhu zvinogona kuratidza akasiyana madhigirii ekuramba kwecorrosion.Magiredhi maviri eStainless simbi anonyanyozivikanwa 304 uye 316. Corrosion chiitiko chemusikirwo, kungofanana nesimbi inogadzika neyakaitenderedza.Muchokwadi, zvishoma zvinhu zvinogona kuitika muchimiro chakachena - goridhe, sirivha, mhangura, uye platinamu mienzaniso mishoma.
Chromium oxide inoumba firimu rekudzivirira rakarongeka
Ngura ndiyo nzira iyo mamorekuru esimbi anosanganidzana neokisijeni mumamorekuru emvura, uye mhedzisiro ivara dzvuku rinowedzera kuipa-kuora zvakawanda zvezvinhu.Pakati peizvi, iron uye carbon simbi zvinonyanya kubatwa nekuora uku.
Simbi isina tsvina ine hunyanzvi hwekuzvarwa nayo hwekuora pamusoro, izvi zvinouya sei?Chromium mumasimbi ese asina tsvina inobata nekukasira muokisijeni, sesimbi.Musiyano ndewekuti chete chidimbu chakatetepa chechromium chinozove oxidized (kazhinji ingori kamorekuru muhukobvu).Zvinoshamisa, iyi nhete yekudzivirira yakasimba kwazvo.
304L simbi isina tsvina ine chitarisiko chakanaka uye mutengo wakaderera wekugadzirisa.304L yakabhurashwa simbi isina simbi haina kuita ngura, saka inowanzoshandiswa mukubika uye kushandiswa kwechikafu.Asi inobatwa nekloridi (kazhinji munzvimbo dzine munyu wakanyanya).Chloride inogadzira mhando yenzvimbo yecorrosion inonzi "corrosion spot" inoenda mukati memukati.
304 simbi isina tsvina ndiyo inonyanya kushandiswa simbi isina tsvina pasi rose.Iine 16% -24% chromium uye inosvika 35% nickel - uye yakaderera mazinga ecarbon uye manganese.Iyo inonyanya kuzivikanwa fomu ye304 simbi isina tsvina ndeye 18-8, kana 18/8 simbi isina tsvina, iyo inoreva 18% chromium uye 8% nickel.
316 simbi isina simbi zvakare yakashandiswa zvakanyanya simbi isina tsvina.Hunhu hwayo hwepanyama uye hwemagetsi hwakafanana ne304 simbi isina tsvina.Musiyano ndewekuti 316 simbi isina tsvina ine 2-3% molybdenum, iyo inowedzera simba uye kusagadzikana kwemarara.Kazhinji mazana matatu akatevedzana masimbi asina tsvina anogona kuve nearuminiyamu inosvika 7%.
304L uye 316Lbrushed Stainless steels(sezvakaita mamwe mazana matatu akatevedzana masimbi asina tsvina) shandisa nickel kuchengetedza yakaderera tembiricha aesthetics.
