Stainless steels ndeyepamusoro-alloy steels iyo ine high corrosion resistance kana ichienzaniswa nedzimwe simbi nekuda kwekuvapo kwehuwandu hwekromium. Kubva pane yavo crystalline chimiro, ivo vakakamurwa kuva matatu marudzi akadai se ferritic, austenitic, uye martensitic simbi. Rimwe boka resimbi dzisina tsvina isimbi inonaya-yakaoma. Iwo musanganiswa wemartensitic uye austenitic simbi.
Giredhi 440C Stainless simbi isimbi yakakwira kabhoni martensitic. Iine simba rakakwirira, ine mwero corrosion resistance, uye kunaka kuomarara uye kupfeka kuramba. Giredhi 440C inokwanisa kuwana, mushure mekurapwa kwekupisa, simba repamusoro, kuoma uye kupfeka kuramba kwearoyi ese asina tsvina. Yayo yakanyanya kabhoni yemukati inokonzeresa maitiro aya, ayo anoita 440C kunyanya kuenderana nemashandisirwo akadai semabhora ebhora uye zvikamu zvevharuvhu.
