SUS410 / SUS420J2 / SUS430 simbi isina simbi mabheji Kuenzanisa：
SUS410: Martensite inomiririra giredhi resimbi, iine simba rakakwirira uye kuomarara kukuru (magnetic); murombo ngura kuramba, haina kukodzera kushandiswa munzvimbo dzinokanganisa zvakanyanya; yakaderera C zvemukati, zvakanaka kushanda, uye pamusoro zvinogona kuomeswa nekupisa kurapwa.
SUS420J2: Martensite inomiririra giredhi resimbi, iine simba rakakwirira uye kuomarara kukuru (magnetic); murombo ngura nemishonga, murombo kugadzira uye formability, uye zvakanaka kusakara nemishonga; inogona kupiswa kupisa kugadzirisa michina zvivakwa. Inoshandiswa zvakanyanya mukugadzirisa mapanga, mabhuti, mavhavha, vatongi, uye tafura.
SUS430: Low chafariz kuwedzera mwero, zvakanaka Kuumbwa uye oxidation nemishonga. Inokodzera midziyo isingadziye kupisa, zvinopisa, midziyo yemumba, kirasi 2 tafura, sinki dzekicheni. Mutengo wakaderera, kushanda zvakanaka chinhu chinotsiva SUS304; yakanaka ngura kuramba, yakajairika isiri-kupisa kurapwa yakaoma yakaoma ferritic simbi isina simbi.

Nheyo yesimbi isina simbi bhora:
Stainless simbi marozari haasi ngura-chiratidzo, asi hazvisi nyore ngura. Nheyo yacho ndeyekuti nekuwedzera kwechromium, dense chromium oxide layer inoumbwa pamusoro pesimbi, iyo inogona kuvharira zvinobatika kubatana zvakare pakati pesimbi nemhepo, kuitira kuti oxygen iri mumhepo isakwanise kupinda musimbi. bhora, nokudaro ichidzivirira mhedzisiro yesimbi marozi ngura.
China National Standards (CNS), maJapan maYunivhesiti Maitiro (JIS) uye American Iron uye Steel Institute (AISI) vanoshandisa manhamba matatu kuratidza akasiyana simbi isina simbi, ayo anonyanya kutaurwa muindasitiri, ayo iwo akateedzana mazana maviri chromium-nickel-manganese -based austenitic Stainless simbi, 300 dzakateedzana ndeye chromium-nickel austenitic simbi isina chinhu, mazana mana akateedzana chromium simbi isina simbi (inowanzozivikanwa sesimbi isina simbi), inosanganisira martensite uye ferrite.
