Ntom, yav tas los hu ua kev sib tsoo tshwj xeeb, yog qhov hnyav (hnyav) ntawm cov khoom hauv ib chav ntim.
Cov ntsuas khoom siv hauv qab no yog t / m3 (tuj / m3), lossis g / cm3 (g / cm3).Yog tias siv kg / m3 (kg / m3) siv, nce tus nqi los ntawm 1000 (* 103).
Cov pa roj carbon steel: 7.81-7.85, cam khwb cia hlau: 7.8, alloy hlau: 7.9, nickel-chromium steel: 7.8
Qhov ntom ntom cov roj carbon steel yog siab dua me ntsis ntawm cov hlau nplaum ferritic thiab Martensitic, tab sis qis me ntsis dua li ntawm Austenitic stainless hlau.Lub resistivity ntawm carbon hlau, hom ferritin, Martensite hom thiab austenitic hom stainless hlau sib lawv liag nce;Qhov kev txiav txim ntawm linear expansion coefficient yog qhov zoo sib xws. Austenitic stainless hlau yog qhov ntau tshaj plaws thaum carbon cov hlau qis tshaj.Cov pa roj carbon steel, hom ferritin thiab Martensitic stainless hlau hom sib nqus, austenitic stainless hlau hom tsis yog hlau nplaum, tab sis nws txias ua haujlwm nyuaj rau hauv kev sib hloov kaum ntau theem yuav tsim cov khoom sib nqus, kev kho cua sov tuaj yeem siv los tshem tawm cov qauv martensitic no thiab rov qab nws tsis-sib nqus.
Piv nrog carbon hlau, austenitic stainless hlau muaj cov yam ntxwv li nram no:
1) Muaj cov khoom tiv thaiv siab, txog 5 zaug ntawm carbon hlau.
2) Cov kab hluav taws xob loj tso tawm qhov sib txawv, 40% loj dua qhov ntawm cov pa roj carbon steel, thiab nrog qhov nce ntawm qhov kub, tus nqi ntawm linear expansion coefficient nce sib txuam.
3) Tsawg thermal conductivity, txog li 1/3 ntawm carbon hlau.
