I-Ferrite iyisixazululo esiqinile sekhabhoni ku-α-Fe, evamise ukumelelwa uphawu "F."Kuinsimbi engagqwali, "i-ferrite" ibhekisela kusisombululo esiqinile sekhabhoni ku-α-Fe, esinokuncibilika kwekhabhoni ephansi kakhulu.Ingancibilikisa kuphela ikhabhoni engaba ngu-0.0008% ekamelweni lokushisa futhi inokunyibilika kwekhabhoni okuphezulu okungu-0.02% ku-727°C.I-Ferrite igcina isakhiwo se-cubic lattice esigxile emzimbeni futhi ivame ukumelwa uphawu "F.
Ngenxa yokuqukethwe kwayo kwekhabhoni ephansi, i-ferrite ikhombisa izakhiwo ezifana nensimbi emsulwa, okuhlanganisa ukudumba okuhle nokuqina, nobude (δ) obucishe bube ngu-45% ukuya ku-50%.Inamandla aphansi nobulukhuni, inamandla aqinile (σb) acishe abe ngu-250 MPa kanye nokuqina kweBrinell (HBS) okungaba ngu-80.
Insimbi engagqwali ye-Ferritic, kumongo wensimbi engagqwali esimweni sayo sesevisi, ngokuyinhloko iqukethe i-ferritic microstructure.Okuqukethwe kwayo kwe-chromium kusuka ku-11% kuya ku-30%, futhi inomzimba omaphakathi we-cubic crystal structure.Okuqukethwe kwensimbi yensimbi engagqwali akuhlobene nokuthi iyinsimbi engagqwali ye-ferritic noma cha.Insimbi engagqwali ye-Ferritic incike kuphela ekutheni, esimweni sayo sesevisi, iqukethe ikakhulukazi i-ferritic microstructure, eyizibuthe.
I-Austenite iyisixazululo esiqinile sekhabhoni ku-γ-Fe, evame ukumelelwa uphawu "A."Igcina i-cubic crystal lattice egxile ebusweni ye-γ-Fe.Ine-carbon solubility ephezulu uma kuqhathaniswa, incibilika cishe u-0.77% wekhabhoni ku-727°C futhi kuze kufike ku-2.11% ikhabhoni ku-1148°C.I-Austenite i-microstructure engakwazi ukuzinza kuphela emazingeni okushisa angaphezu kuka-727°C.I-Austenite iyi-ductile futhi iyisakhiwo esincane esidingekayo kumamaki ensimbi amaningi uma ingaphansi kokusebenza okushisayo emazingeni okushisa aphakeme.I-Austenite ayiyona i-magnetic.
