Khoom Description

Carbon steel yog hlau - carbon alloy, uas muaj txog li 2.1 wt.% carbon. Rau cov pa roj carbon steel, tsis muaj qhov tsawg kawg nkaus cov ntsiab lus ntawm lwm cov hlau alloying, txawm li cas los xij, lawv feem ntau muaj manganese. Qhov siab tshaj plaws manganese, silicon thiab tooj liab cov ntsiab lus yuav tsum tsawg dua 1.65 wt.%, 0.6 wt.% thiab 0.6 wt.%, feem.

Hom carbon steel thiab lawv cov khoom

Cov pa roj carbon steel tuaj yeem muab faib ua peb pawg raws li nws cov ntsiab lus carbon: qis- carbon steel (los yog me me- carbon steel), nruab nrab - carbon steel thiab siab - carbon steel . Lawv cov ntsiab lus carbon, microstructure thiab cov khoom sib piv raws li hauv qab no:

Cov ntsiab lus carbon (wt.%)	Microstructure	Cov khoom	Piv txwv
Tsawg- carbon steel	< 0.25	Ferrite, pearlite	Tsawg hardness thiab nqi. High ductility, toughness, machinability thiab weldability
Nruab nrab- carbon steel	0.25 – 0.60	Martensite	Tsawg hardenability, nruab nrab lub zog, ductility thiab toughness
Siab - carbon steel	0.60 – 1.25	Pearlite	High hardness, lub zog, tsawg ductility
