Classification ntawm carbon steel

(1) Raws li daim ntawv thov, carbon steel tuaj yeem muab faib ua peb hom: carbon steel qauv, carbon hlau steel thiab dawb-txiav cov qauv hlau, thiab carbon structural steel tau muab faib ua engineering siv steel thiab tshuab tsim cov qauv hlau;
(2) Raws li txoj kev smelting, nws tuaj yeem muab faib ua qhib-hearth steel thiab converter steel;
(3) Raws li txoj kev deoxidation, nws tuaj yeem muab faib ua boiling steel (F), tua steel (Z), semi-tua steel (b) thiab tshwj xeeb tua steel (TZ);
(4) According to the carbon content, carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25%-0.6%) and high carbon steel (WC>0.6 feem pua ​​);
(5) Raws li cov hlau zoo, carbon hlau tuaj yeem muab faib ua cov pa roj carbon zoo tib yam (ntau dua phosphorus thiab sulfur cov ntsiab lus), cov pa roj carbon zoo (cov ntsiab lus qis phosphorus thiab sulfur) thiab cov hlau zoo siab (qis phosphorus thiab sulfur). cov ntsiab lus)) thiab super zoo steel.
