Umehluko omkhulu phakathiinsimbi engenacalakanye ne-Ferrititic yensimbi engenacala ezinhlakeni nasezakhiweni zazo.
I-Auntenitic stainless yinhlangano ehlala izinzile kuphela emazingeni okushisa aphezulu kuneminyaka engama-727 ° C. Kubonisa i-Plastic enhle futhi yisakhiwo esikhethwayo samanye ama-steel ecubungula amazinga okushisa aphakeme. Ngokwengeziwe, insimbi ye-auntenitic ayizibuthe.
UFerrite uyisisombululo esiqinile sekhabhoni esichithwe kwi-α-iron, kuvame ukufanekisa njengo-F. Ininsimbi engagqwali, "UFerrite" ubhekisa kwikhambi eliqinile lekhabhoni ku-α-iron, libonakaliswa yi-carbon solubility yalo elilinganiselwe. Emazingeni okushisa asekamelweni, kungahlukana kuphela ku-0.0008% carbon, kufinyelela indawo enkulu yekhabhoni ye-0.02% ku-727 ° C, ngenkathi kugcinwa i-cubic lattice egxile emzimbeni. Kuvame ukuvezwa ngophawu F.
Ngakolunye uhlangothi, i-ferriticinsimbi engagqwalikubhekiswa ngensimbi engenacala kakhulu eyakhiwe ngesakhiwo se-Ferritic ngesikhathi sokusetshenziswa. Ine-Chromium ebangeni lama-11% kuya ku-30%, enesihloko esigxile emzimbeni we-cubic crystal. Okuqukethwe kwensimbi yensimbi engenasici akuhlobene nokuthi kuhlukaniswa njengensimbi engenacala.
Ngenxa yokuqukethwe kwayo okuphansi kwekhabhoni, ama-ferritic wensimbi ekhombisa izakhiwo ezifana nensimbi emsulwa, kufaka phakathi i-plastiki enhle kakhulu kanye nokuqina kwepulasitiki nenani eliphakeme (Δ) lika-45% kuya ku-50%. Kodwa-ke, amandla alo nobulukhuni bawo kuphansi kakhulu, ngamandla ashubile (σb) acishe abe ngu-250 MPA kanye nobulukhuni be-brinell (HBS) ka-80.
