Insimbi Engagqwali isifinyezo sensimbi engagqwali engagqwali. Ibizwa ngokuthi insimbi engagqwali ene-medium ebuthakathaka ebolile noma i-Stainless Steel, njengomoya, umusi namanzi. Uhlobo lwensimbi olubolile i-medium ebolile yamakhemikhali (i-asidi, i-alkali, usawoti, njll.) lubizwa ngokuthi insimbi emelana ne-asidi.
Ngokwesimo senhlangano, ingahlukaniswa ibe yinsimbi ye-martensitic, insimbi ye-ferritic, insimbi ye-austenitic, insimbi engagqwali ye-austenite – ferrite (isigaba esiphindwe kabili) kanye nensimbi engagqwali eqinisayo. Ngaphezu kwalokho, ingahlukaniswa ibe yinsimbi engagqwali ye-chromium, insimbi engagqwali ye-chromium nickel kanye nensimbi engagqwali ye-chromium manganese nitrogen ngokwezinto ezikuyo.
Igama elithi “insimbi engagqwali” alibhekiselwa nje kuphela ensimbini engagqwali emsulwa kodwa nasezinhlotsheni ezingaphezu kwekhulu zemboni yensimbi engagqwali. Futhi ukuthuthukiswa kwensimbi ngayinye engagqwali kusebenza kahle ekusetshenzisweni kwayo okuthile. Ngakho-ke, isinyathelo sokuqala ukuthola ukusetshenziswa, bese unquma uhlobo olufanele lwensimbi ngokwezici zohlobo ngalunye lwensimbi engagqwali.
Ngenxa yokumelana kwayo nokugqwala okuhle kakhulu, ukuhambisana kwayo kanye nokuguquguquka kwayo okunamandla emazingeni okushisa abanzi, insimbi engagqwali nayo iyinto eluhlaza enhle kakhulu yabaphakeli bezivalo.
