Kupokana kwekuora kwesimbi isina tsvina kunoenderana nechromium, asi nekuti chromium chimwe chezvikamu zvesimbi, nzira dzekudzivirira dzinosiyana.Kana kuwedzera kwechromium kunosvika 10.5%, kupikisa kwemuchadenga kwesimbi kunowedzera zvakanyanya, asi kana chromium yemukati yakakwira, kunyangwe kushorwa kwecorrosion kuchiri kuvandudzwa, hazvisi pachena.Chikonzero ndechekuti alloying simbi ine chromium inoshandura rudzi rweokisidhisi yepamusoro kuita okisijeni yepamusoro yakafanana neyakaumbwa pachene chromium metal.Iyi yakanyatso kunamatira chromium-rich oxide inodzivirira pamusoro kubva kune imwe oxidation.Iyi oxide layer yakatetepa zvakanyanya, kuburikidza iyo iyo yakasikwa kupenya kwesimbi inopenya, ichipa Stainless simbi nzvimbo yakasarudzika.Uyezve, kana iyo yekumusoro layer yakakuvadzwa, iyo yakafumurwa simbi inotarisana nemhepo kuti igadzirise pachayo, gadzirazve iyi oxide "passivation film", uye irambe ichiita basa rekudzivirira.Nokudaro, zvinhu zvose zvesimbi zvisina tsvina zvine chimiro chakafanana, ndiko kuti, chromium yemukati iri pamusoro pe10.5%.Kuwedzera kune chromium, iyo inowanzo shandiswa alloying zvinhu ndeye nickel, molybdenum, titanium, niobium, mhangura, nitrogen, nezvimwewo, kuzadzisa zvinodiwa zvekushandisa kwakasiyana-siyana kwechimiro uye zvimiro zvesimbi isina tsvina.
304 isimbi isina tsvina inoshandiswa zvakanyanya kugadzira midziyo uye zvikamu zvinoda kuita kwakanaka kwese (corrosion resistance uye formability).
301 simbi isina tsvina inoratidza basa riri pachena rinoomesa chiitiko panguva yekuchinja, uye inoshandiswa muzviitiko zvakasiyana zvinoda simba rakakwirira.
302 Stainless simbi inongosiyana ye304 Stainless simbi ine yakakwira kabhoni yemukati, iyo inogona kuwana simba repamusoro nekukunguruka kunotonhora.
302B imhando yesimbi isina tsvina ine yakakwira silicon yemukati, ine yakanyanya kupikisa kune yakanyanya tembiricha oxidation.
303 uye 303S e simbi isina tsvina ine sulfuri uye selenium mahara, uye anoshandiswa mukushandisa uko kunonyanya kudiwa kucheka mahara uye kumusoro kwepamusoro.303Se simbi isina tsvina inoshandiswawo kugadzira zvikamu zvinoda kupisa kupisa, nekuti pasi pemamiriro ezvinhu aya, iyi simbi isina tsvina ine basa rakanaka rinopisa.
304L yakaderera kabhoni musiyano we304 Stainless simbi inoshandiswa panodiwa welding.Iyo yakaderera kabhoni yemukati inoderedza kunaya kwecarbide munzvimbo yakakanganiswa nekupisa pedyo neweld, izvo zvinogona kutungamirira kune intergranular corrosion (weld erosion) yesimbi isina tsvina mune dzimwe nharaunda.
304N initrogen-ine simbi isina tsvina, uye nitrogen inowedzerwa kuwedzera simba resimbi.
305 uye 384 simbi dzisina tsvina dzine nickel yakakwira uye ine basa rakaderera rekuomesa chiyero, zvichiita kuti ive yakakodzera kune akasiyana mafomu anoda kutonhora kwakanyanya.
308 simbi isina tsvina inoshandiswa kugadzira maelectrodes.
309 , 310, 314 uye 330 simbi dzisina tsvina dzinenge dzakakwirira, kuitira kuti uvandudze kupikisa oxidation uye simba rinokambaira resimbi pakupisa kukuru.30S5 uye 310S akasiyana e309 uye 310 simbi isina tsvina, mutsauko uripo ndewekuti kabhoni yemukati yakadzikira, kuitira kuderedza kunaya kwecarbides pedyo neweld.330 simbi isina tsvina ine yakanyanya kupikisa kune carburization uye nekushisa kuvhunduka kuramba.
Mhando 316 uye 317 simbi dzisina simbi dzine aruminiyamu uye nekudaro dzinoshingirira zvakanyanya kune gomba corrosion kupfuura 304 simbi isina tsvina munzvimbo dzemugungwa nemakemikari indasitiri.Pakati pavo, 316 Stainless steel variants zvinosanganisira yakaderera kabhoni Stainless simbi 316L, nitrogen-ine yakakwirira-yakasimba Stainless simbi 316N, uye mahara-kucheka Stainless simbi 316F ine yakakwirira sulfur content.
321, 347 uye 348 isimbi isina tsvina yakagadzikana netitanium, niobium pamwe ne tantalum uye niobium zvakateerana, iyo yakakodzera kune welding zvikamu zvinoshandiswa pakupisa kwakanyanya.348 imhando yesimbi isina tsvina yakakodzera indasitiri yemagetsi enyukireya, ine zvimwe zvinorambidzwa pahuwandu hwakasanganiswa hwetantalum nedhaimani.
