Ko te Ferrite he otinga waro totoka i roto i te α-Fe, he tohu "F."I rotokowiri tira, "ferrite" e pā ana ki te wairewa totoka waro i roto i te α-Fe, he iti rawa te wairewa waro.Ka taea te memeha noa mo te 0.0008% waro i te pāmahana rūma, ā, he 0.02% te roa o te waro ki te 727°C.Kei te pupuri a Ferrite i te hanganga kurupae-a-tinana-a-tinana me te tohu "F.
Na te iti o te waro i roto, ka whakaatu te ferrite i nga ahuatanga e rite ana ki te rino parakore, tae atu ki te ngawari me te pakari, me te whakaroa (δ) tata ki te 45% ki te 50%.He iti ake te kaha me te pakeke, me te kaha tensile (σb) tata ki te 250 MPa me te pakeke Brinell (HBS) tata ki te 80.
Ferritic kowiri tira, i roto i te horopaki o te kowiri tira i roto i tona ahua ratonga, matua ngā o te microstructure ferritic.Ko ona ihirangi chromium mai i te 11% ki te 30%, a, he hangahanga kiripiri-a-tinana.Ko te ihirangi rino o te kowiri tira kaore e pa ana ki te mea he kowiri tira ferritic kaore ranei.Ko te kowiri tira Ferritic anake e whakawhirinaki ana ki te ahua o te ratonga, he hangahanga moroiti ferritic, he autō.
Ko Austenite he otinga waro totoka i roto i te γ-Fe, he maha nga tohu "A."Kei te pupuri i te kurupae karaehe o te γ-Fe.He nui te waro wairewa, he tata ki te 0.77% te waro ki te 727°C tae atu ki te 2.11% te waro ki te 1148°C.Ko te Austenite he hangahanga moroiti ka taea anake te noho i nga pāmahana teitei ake i te 727°C.He ductile te Austenite me te hanganga moroiti e hiahiatia ana mo te nuinga o nga tohu rino ka tukuna ki te mahi wera i nga pāmahana teitei.Ko Austenite ehara i te aukume.
