Lub cev muaj zog ntawm stainless hlau
Jun 05, 2023
Muab piv rau carbon steel
1. Ceev ceev
Qhov ntom ntawm carbon steel yog me ntsis siab dua li ntawm ferritic thiab martensitic stainless hlau, tab sis me ntsis qis dua li ntawm austenitic stainless hlau;
2. Kev tiv thaiv
Lub resistivity nce nyob rau hauv qhov kev txiav txim ntawm carbon steel, ferrite, martensite thiab austenitic stainless hlau;
3. Qhov kev txiav txim ntawm linear expansion coefficient kuj zoo sib xws, nrog austenitic stainless hlau muaj qhov siab tshaj plaws thiab carbon hlau muaj qhov qis tshaj;
4. Carbon steel, ferritic stainless hlau thiab martensitic stainless hlau muaj hlau nplaum, thaum austenitic stainless hlau tsis muaj hlau nplaum, tab sis hlau nplaum yuav raug generated thaum txias ua hauj lwm hardening generates Martensite transformation. Kev kho cua sov tuaj yeem siv los tshem tawm cov qauv Martensite no thiab rov ua kom nws tsis yog hlau nplaum.
Piv nrog carbon steel, austenitic stainless hlau muaj cov yam ntxwv hauv qab no:
1) Cov hluav taws xob tiv taus siab, kwv yees li 5 npaug ntawm cov hlau.
2) Qhov loj coefficient ntawm linear expansion yog 40 feem pua siab dua cov pa roj carbon steel, thiab raws li qhov kub thiab txias, tus nqi ntawm cov coefficient ntawm linear expansion kuj nce raws li.
3) Tsawg thermal conductivity, kwv yees li ib feem peb ntawm cov pa roj carbon steel.
