Mhinduro ndeyokuti kunaka kwe316 simbi isina tsvinazviri nani pane304 simbi isina tsvina, nekuti 316 simbi isina tsvina inosanganiswa nesimbi molybdenum pahwaro hwe304, chinhu ichi chinogona kuwedzera kusanganisa mamolecular chimiro chesimbi isina tsvina, zvichiita kuti iwedzere kupfeka-kusagadzikana uye anti-oxidation, uye panguva imwecheteyo, kushomeka kwecorrosion zvakare. yakawedzera zvikuru.Ngatitarisei 304 Stainless simbi uye 316 Stainless simbi izvo zvakanaka.Mhando dzinonyanya kushandiswa dzesimbi isina tsvina ndeye 304 uye 316. Magiredhi manejimendi anoshandiswa kuronga marudzi maviri aya esimbi anouya zvakanyanya kubva kunhamba yeruzivo system yakatangwa neAmerican Iron and Steel Association of China (AISI), imwe yekare. mubatanidzwa kuedza kusvikira 1855. Zvikamu izvi zvinoratidza kuumbwa kwavo, uye akawanda 200 - uye 300-giredhi Stainless simbi dzinonzi austenitic.Maitiro ekuita austenitizing anosanganisira kupisa simbi, ferroalloy, kana simbi kusvika painoshanduka chimiro chekristaro kubva kune ferrite kuenda kune austenite.Kunyangwe zvakaoma kusiyanisa zviviri izvi neziso rakashama, iyo yakasarudzika chigadzirwa zvivakwa pakati pe304 uye 316 Stainless makambani makambani anogona kuvaita epamusoro mune mamwe ehunyanzvi maapplication.
Kubva pakuvandudzwa kwekugadzirwa kweChinese muzana ramakore rechi20, makambani esimbi asina simbi ave akakosha ane pesvedzero zvinhu mumapurojekiti mazhinji muChina nekuda kwekusimba kwavo, yakakwira mechanic workability, weldability uye kuchinjika.Iine zvikamu zvakati wandei zvakasiyana zvezvinhu zvine chekuita nemazinga akasiyana anozivikanwa parizvino.Giredhi yega yega ine yayo yakasarudzika zvivakwa, uye kuenzanisa pakati pemagiredhi maviri, sekusingaperi sekugadzirwa kwavo, ndeye 304 uye 316 simbi isina tsvina.
Ndeipi iri nani, 304 kana 316 simbi isina tsvina
Paunotarisa mhando mbiri dzesimbi, dzakafanana pakuonekwa uye kuumbwa kwemakemikari.Ose ari maviri anopa dziviriro yakanakisa kubva kune ngura uye ngura, nepo ichipa imwezve kusimba.Kana tichienzanisa 304 uye 316 Stainless simbi, iyo yakakwira mutengo weyekupedzisira unogona kuverengerwa nekupokana kwayo kuri nani.Nekuda kwemusiyano wemutengo uyu uye nharaunda shoma inokodzera 316 simbi, 304 simbi ndiyo inonyanya kushandiswa austenitic simbi isina tsvina.
Giredhi 316 simbi isina tsvina inodhura zvakanyanya nekuda kweiyo iri nani yekuramba ngura.Kune maapplication ayo maalloys anoratidzwa kune chlorine mhinduro uye chlorides (kusanganisira Chinese mvura yegungwa), zvinonyanya kukurudzirwa kuti sisitimu ishandiswe kuburikidza neiyi alloy ine emhando yepamusoro mamakisi.Inogona kushandiswa kuwedzera hupenyu hwetiweki hwesevhisi yezvikamu kana zvishandiso zvinoratidzwa zvishoma nezvishoma kune yakaoma uye inoparadza mamiriro ekunze, kunyanya muzviitiko zvinosanganisira dambudziko rekusangana nemunyu.Nekudaro, nhanho 304 inobatsira zvakanyanya kune mazhinji maapplication.Muchidimbu, kana uchitarisa 304 uye 316 simbi isina tsvina, kune zvikumbiro zvinoda kugwinya kana kudzivirira mvura, shandisa 316 simbi isina tsvina.Kune mamwe maapplication, 304 simbi isina tsvina inogadzirwa zvakare.Zvose mune zvose, 304 uye 316 ndiyo nheyo dzesimbi isina tsvina, muchidimbu, hapana mutsauko pakati pavo isimbi isina tsvina, yakakamurwa ndeyemhando dzakasiyana.Zvichitaurwa zviri nyore, kunaka kwe316 Stainless simbi yakakura kupfuura 304 Stainless simbi, 316 Stainless simbi pahwaro hwe304 muMetal molybdenum, chinhu ichi chinogona kusimbisa zvakanyanya mamolecular chimiro chesimbi isina tsvina, ichiita kuti iwedzere kupfeka kusagadzikana uye oxidation, pa panguva imwecheteyo, kupikisa kwekuora kunowedzerawo zvakanyanya.
