Kev txhais cov khoom sib xyaw thiab cov txheej txheem tsim khoom ntawm cov kav hlau carbon

Cov Yeeb Nkab Hlau Carbon yog cov yeeb nkab ua los ntawm cov hlau carbon ua cov khoom tseem ceeb. Nws cov ntsiab lus carbon feem ntau yog nruab nrab ntawm 0.06% thiab 1.5%, thiab muaj me ntsis manganese, silicon, sulfur, phosphorus thiab lwm yam ntsiab lus. Raws li cov qauv thoob ntiaj teb (xws li ASTM, GB), cov yeeb nkab hlau carbon tuaj yeem muab faib ua peb pawg: cov hlau carbon qis (C≤0.25%), cov hlau carbon nruab nrab (C = 0.25% ~ 0.60%) thiab cov hlau carbon siab (C≥0.60%). Ntawm lawv, cov yeeb nkab hlau carbon qis yog cov siv dav tshaj plaws vim lawv cov txheej txheem zoo thiab weldability.
