Intshayelelo
Iintsimbi ezingenastainless ziziintsimbi ezine-alloy ephezulu ezinokumelana ne-corrosion ephezulu kunezinye iintsimbi ngenxa yobukho bezixa ezikhulu zechromium kuluhlu lwe-4 ukuya kwi-30%.Iintsimbi ezingenasici zihlelwa zibe yi-martensitic, i-ferritic kunye ne-austenitic ngokusekelwe kwisakhiwo sabo se-crystalline.Kwi-addititon, benza elinye iqela elibizwa ngokuba yi-precipitation-hardened steels, edibeneyo ye-martensitic kunye ne-austenitic steels.
Le datha ilandelayo iya kunika iinkcukacha ezithe vetshe malunga nebakala 347H intsimbi engatyiwa, eqine kancinci kunebakala 304 lentsimbi.
