Simbi dzisina tsvina dzinozivikanwa semasimbi epamusoro-alloy.Izvo zvinosanganisira 4-30% yechromium.Iwo akakamurwa kuita martensitic, austenitic, uye ferritic simbi zvichibva pane yavo crystalline chimiro.
Giredhi 317 simbi isina tsvina ishanduro yakagadziridzwa ye316 simbi isina tsvina.Iine simba rakakwirira uye rinopesana nekuora.Iyo inotevera dhatabheti inopa rumwe ruzivo nezve giredhi 317 Stainless simbi.
