1. Te ferrite
Ko te Ferrite he wairewa totoka interstitial i hanga e te waro memeha ki -Fe. Ko te nuinga o nga wa e kiia ana ko te F.Kei te pupuri i te hanganga whaanui kubiko nui o te alpha -Fe.Ferrite he iti te ihirangi waro, a ko ona taonga miihini e tata ana ki te rino parakore, te kirihou teitei me te uaua, me te iti o te kaha me te pakeke.
2. Ko te austenite
Austenite Ko te otinga totoka interstitial o te waro rewa i roto i -Fe, te nuinga o whakapuakina rite ranei A.Kei te pupuri i te hanganga kurupae kubiko-kanohi o te gamma-Fe.Austenite he waro whakarewa teitei ake i te ferrite, a ko ona taonga miihini e tohuhia ana e te kirihou pai, te iti o te kaha, te iti o te pakeke me te ngawari o te whakarereke kirihou.

3. Te cimentite
Ko te Cementite he puhui i hangaia e te rino me te waro, ko tona tauira matū ko Fe3C.Kei roto i te 6.69% te waro me te hanganga karaihe matatini.Ko te cimentite he tino pakeke te pakeke, he kino te kirihou, tata kore, he waahi pakeke me te pakarukaru.Cementite te mahi whakapakari i te waro waro.
4. Pereti
Ko te peariki he ranunga miihini o te ferrite me te cimentite, ko te nuinga o te waa e tohuhia ana e te P.Ko te nuinga o te waro o te pearlite he 0.77%, a ko ona taonga miihini kei waenga i te ferrite me te cimentite, me te kaha nui, te pakeke ngawari me etahi kirihou.Ma te maimoatanga wera, ka taea te tohatoha i te cementite i roto i te ahua granular i runga i te matrix ferrite. Ko tenei ahua o te hanganga e kiia ana ko te pearlite porohita, a he pai ake tana mahi matawhānui.
5. Ledeburite
Ko te Leutenite he ranunga miihini o te austenite me te cimentite, ko te tikanga ko te Ld.Ko te waro toharite o te Leutenit ko te 4.3%.I te whakamahana ki te 727 ℃, ka huri te austenite i roto i te leustenite ki te pearlite.Na i raro i te 727 ℃, ko te leutenite he pearlite me te cementite iti, ko te iti o te hanganga o te L. Ko te Leutenite he mea hanga mai i te cimentite, no reira he uaua, he pakarukaru hoki ona ahuatanga miihini.
