Ferrochrome yog ferroalloy feem ntau muaj xws li chromium thiab hlau. Nws yog ib qho ntawm cov neeg ua haujlwm tseem ceeb alloying siv hauv kev lag luam steel. Dhau li ntawm lub ntsiab Cheebtsam chromium thiab hlau, nws kuj muaj impurities xws li carbon, silicon, sulfur, thiab phosphorus. Ferrochrome muaj 55%–75% chromium thiab raug cais raws li cov ntsiab lus carbon rau hauv siab -carbon (4%–10% C), nruab nrab-carbon (0.5%–4% C), qis-carbon (0.15%–0.5% C), thiab qis-carbon (Less dua. High-carbon ferrochrome tseem hu ua carbon ferrochrome, thaum nruab nrab, qis, thiab qis-carbon ferrochrome kuj hu ua refined ferrochrome.
Ib hom high -carbon ferrochrome uas ua los ntawm chromium ore nrog ib tug tsawg chromium- rau - hlau piv, muaj 50% -55% Cr, yog hu ua cub tawg nqi ferrochrome. Kuj tseem muaj nitrogen-muaj ferrochrome uas muaj 2%–10% N, siv los ua ib tus neeg sawv cev nitrogen, los yog ferronitride ferrochrome.
