Hariho ubwoko butanu bwibanze bwaibyuma bidafite ingese:austenitis, ferritic, martensitike, duplex, hamwe nimvura ikomera.
.Bakoreshwa cyane mubyiciro byibyuma.
(2) Ferrite ni magnetique, na chromium nibintu byayo nyamukuru, hamwe na 17%.Ibi bikoresho bifite imbaraga zo kurwanya okiside.
.
.Zirwanya cyane ruswa ya chloride.Ibisubizo byiza.
(5)Ibintu bisanzwe bya chromium mumvura igwa ibyuma bitagira umuyonga ni 17, kandi hiyongereyeho umubare munini wa nikel, umuringa na niobium, ushobora gukomera kubera imvura no gusaza.
Ukurikije imiterere ya metallografiya, irashobora kugabanywamo:
(1)Ibyuma bya ferritic (400 serie), chromium ibyuma bidafite ingese, bigereranywa na Gr13, G17, Gr27-30;
(2)Icyuma cya Austenitike (300 serie), chromium-nikel ibyuma bitagira umwanda, bigaragazwa cyane na 304, 316, 321, nibindi.;
(3)Icyuma cya Martensitike (200 serie), chromium-manganese ibyuma bitagira umwanda, ibirimo karubone nyinshi, bigaragazwa cyane na 1Gr13, nibindi.
