Ferrite yog cov pa roj carbon ua pa hauv α-FE, feem ntau sawv cev los ntawm lub cim "F." HauvStainless hlau, "Ferrite" yog hais txog cov pa roj carbon cov tshuaj hauv α-FER, uas muaj cov pa roj solubility heev. Nws tsuas yog ploj mus txog 0.0008% cov pa roj carbon nyob rau hauv chav tsev thiab muaj cov pa roj cua ntau tshaj plaws ntawm 0.02% ntawm 727 ° C. Ferrite tswj hwm ib lub cev-nruab nrab sau lo lus sau lo lus teb cov lus dag ntxias thiab feem ntau sawv cev los ntawm lub cim "F.
Vim tias nws cov ntsiab lus carbon qis, ferrite cov khoom ua tau zoo ib yam li cov hlau ntshiab, suav nrog kev ua haujlwm ntshiab thiab tawv (Δ) ntawm kwv yees li 45% txog 50%. Nws muaj qis dua lub zog thiab hardness, nrog lub tensile muaj zog (ulb) ntawm kwv yees li 250 MPa thiab lub harinell hardness (HBS) ntawm li 80.
Cov hlau ferritic stainless, nyob rau hauv cov ntsiab lus ntawm stainless hlau hauv nws cov kev pabcuam lub xeev, feem ntau muaj ntawm Ferritic Micrubtructure. Nws cov ntsiab lus Chromium ranges los ntawm 11% mus rau 30%, thiab nws muaj lub cev-nruab nrab cubic crystal crystal. Cov ntsiab lus hlau ntawm stainless hlau tsis muaj feem xyuam rau seb nws yog ferritic stainless hlau lossis tsis. Lub xeev ferritic sterritic nyob ntawm seb, nyob rau hauv nws lub xeev pabcuam, nws muaj ntawm Ferritic Microstructure, uas yog sib nqus.
Austenite yog cov pa roj carbon ua pa hauv γ-fe, feem ntau sawv cev los ntawm lub cim "A." Nws tswj hwm lub ntsej muag-nruab nrab ntawm cubic crystal lattice ntawm γ-FE. Nws muaj tus muaj zog ntau dua rau cov menyuam ua haujlwm, yaj txog 0.77% cov pa roj 77% ntawm 727 ° C thiab txog 2.11% carbon ntawm 1148 ° C. Austenite yog microstructure uas tuaj yeem ruaj khov tsuas yog nyob rau ntawm qhov kub siab dua 727 ° C. Austenite yog lub microstructure thiab yog cov microstructure rau feem ntau cov qhab nia steel thaum raug rau kub ua haujlwm ntawm kev nce kub. Austenite tsis yog sib nqus.

Cov hlau ferritic stainless, nyob rau hauv cov ntsiab lus ntawm stainless hlau hauv nws cov kev pabcuam lub xeev, feem ntau muaj ntawm Ferritic Micrubtructure. Nws cov ntsiab lus Chromium ranges los ntawm 11% mus rau 30%, thiab nws muaj lub cev-nruab nrab cubic crystal crystal. Cov ntsiab lus hlau ntawm stainless hlau tsis muaj feem xyuam rau seb nws yog ferritic stainless hlau lossis tsis. Lub xeev ferritic sterritic nyob ntawm seb, nyob rau hauv nws lub xeev pabcuam, nws muaj ntawm Ferritic Microstructure, uas yog sib nqus.
