Ferrite yog cov kua roj carbon ntau hauv α-Fe, feem ntau sawv cev los ntawm lub cim "F."Hauvstainless hlau, "ferrite" yog hais txog cov kua roj carbon monoxide hauv α-Fe, uas muaj cov pa roj carbon solubility tsawg heev.Nws tsuas tuaj yeem yaj txog 0.0008% carbon ntawm chav tsev kub thiab muaj qhov siab tshaj plaws carbon solubility ntawm 0.02% ntawm 727 ° C.Ferrite tuav lub cev-qhov nruab nrab qhov cubic lattice qauv thiab feem ntau sawv cev los ntawm lub cim "F.
Vim nws cov ntsiab lus tsis tshua muaj carbon, ferrite nthuav tawm cov khoom zoo ib yam li cov hlau ntshiab, nrog rau cov khoom zoo thiab cov tawv nqaij, nrog rau qhov elongation (δ) ntawm kwv yees li 45% mus rau 50%.Nws muaj qis zog thiab hardness, nrog lub zog tensile (σb) ntawm kwv yees li 250 MPa thiab Brinell hardness (HBS) txog li 80.
Ferritic stainless hlau, nyob rau hauv cov ntsiab lus ntawm stainless hlau nyob rau hauv nws cov kev pab cuam lub xeev, feem ntau muaj ib tug ferritic microstructure.Nws cov ntsiab lus chromium nyob ntawm 11% mus rau 30%, thiab nws muaj lub cev-centered cubic crystal qauv.Cov ntsiab lus hlau ntawm stainless hlau tsis cuam tshuam txog seb nws puas yog ferritic stainless hlau los yog tsis.Ferritic stainless hlau tsuas yog nyob ntawm seb, nyob rau hauv nws cov kev pab cuam lub xeev, nws muaj tsuas yog ib tug ferritic microstructure, uas yog sib nqus.
Austenite yog cov kua roj carbon ntau hauv γ-Fe, feem ntau sawv cev los ntawm lub cim "A."Nws tuav lub ntsej muag-centered cubic crystal lattice ntawm γ-Fe.Nws muaj cov pa roj carbon ntau solubility, dissolving txog 0.77% carbon ntawm 727 ° C thiab mus txog 2.11% carbon ntawm 1148 ° C.Austenite yog microstructure uas tuaj yeem ruaj khov ntawm qhov kub siab tshaj 727 ° C.Austenite yog ductile thiab yog qhov microstructure xav tau rau feem ntau cov qib steel thaum raug kub ua haujlwm ntawm qhov kub siab.Austenite tsis yog hlau nplaum.
