Insimbi Engagqwali imfushane ngensimbi engamelana ne-asidi engagqwali. Ibizwa nge-Stainless Steel ene-corrosive medium ebuthakathaka noma i-Stainless Steel, njengomoya, isitimu namanzi. Uhlobo lwensimbi olugqwalisa i-acid corrosive medium (i-asidi, i-alkali, usawoti, njll.) ibizwa ngensimbi engamelana ne-asidi.
Ngokwesimo senhlangano, ingahlukaniswa ngensimbi ye-martensitic, insimbi ye-ferritic, insimbi ye-austenitic, i-austenite - i-ferrite (isigaba esikabili) insimbi engagqwali kanye nemvula eqinisa insimbi engagqwali. Ngaphezu kwalokho, ingahlukaniswa ngensimbi engagqwali ye-chromium, insimbi engagqwali ye-chromium nickel ne-chromium manganese nitrogen insimbi engagqwali ngokuya ngokwengxenye yayo.
Igama elithi “insimbi engagqwali” alibhekiselwa nje ensimbini engagqwali ehlanzekile kuphela kodwa kunezinhlobo ezingaphezu kwekhulu zemboni yensimbi engagqwali. Futhi ukuthuthukiswa kwensimbi engagqwali ngayinye kunokusebenza okuhle ezinhlelweni zabo ezithile. Ngakho-ke, isinyathelo sokuqala ukuthola ukusetshenziswa, bese unquma uhlobo olufanele lwensimbi ngokwezimpawu zohlobo ngalunye lwensimbi engagqwali.
Ngenxa yokumelana nokugqwala okuhle kakhulu, ukuhambisana kanye ne-ductility eqinile ebangeni lokushisa elibanzi, insimbi engagqwali iphinde ibe yimpahla eluhlaza enhle kakhulu yabahlinzeki bezimpawu.
