Musiyano mukuru pakatiaustenitic simbi isina tsvinauye ferritic Stainless simbi iri muzvimiro zvavo uye zvimiro.
Austenitic Stainless steel isangano rinoramba rakagadzikana chete patembiricha inodarika 727°C.Iyo inoratidzira plastiki yakanaka uye ndiyo inosarudzika chimiro chesimbi dzakawanda dziri pasi pekumanikidzwa kugadzirisa patembiricha yakakwira.Uyezve, austenitic simbi haisi-magnetic.
Ferrite mhinduro yakasimba yekabhoni yakanyungudutswa mu α-iron, inowanzofananidzirwa seF. Insimbi isina ngura, "ferrite" inoreva mhinduro yakasimba yekabhoni mu α-iron, inoratidzirwa nekunyungudika kwayo kabhoni.Patembiricha yemumba, inogona kungonyungudika inosvika 0.0008% kabhoni, ichisvika pakunyungudika kwekabhoni ye0.02% pa727°C, uku ichichengeta cubic lattice yemuviri.Inowanzomiririrwa nechiratidzo F.
Kune rumwe rutivi, ferriticsimbi isina ngurainoreva simbi isina tsvina inonyanya kuumbwa neferritic chimiro panguva yekushandiswa.Iine chromium muhuwandu hwe11% kusvika 30%, ine muviri-yakatarisana necubic crystal chimiro.Iyo simbi yesimbi yesimbi isina hukama haina hukama kana inorondedzerwa se ferritic simbi isina tsvina.
Nekuda kwekuderera kwayo kabhoni, ferritic Stainless simbi inoratidza zvivakwa zvakafanana nesimbi yakachena, kusanganisira yakanakisa plastiki uye kusimba ine elongation rate (δ) ye45% kusvika 50%.Nekudaro, kusimba kwayo nekuoma kwayo kwakadzikira, iine simba rekusimba (σb) rinosvika mazana maviri nemakumi mashanu MPa uye kuomarara kweBrinell (HBS) ye80.
