FerroChrome
Grutte:1-100 mm
Ferrochroom (FeCr) is in legering fan chromium en izer dy't tusken 50% en 70% chromium befettet. Mear dan 80% fan 'e wrâldferrochrome wurdt brûkt by de produksje fan roestfrij stiel.Neffens koalstofynhâld kin it wurde ferdield yn: Ferrochroom / HCFeCr mei hege koalstof (C: 4% -8%), Medium koalstofferrochroom / MCFeCr (C: 1% -4%), Ferrochroom mei leech koalstof / LCFeCr (C: 0.25) %-0,5%),Micro carbon ferrochroom/MCFeCr: (C:0,03 0,15%).

Oanfraach:
①Brûkt yn 'e produksje fan roestfrij stiel,RVS hinget ôf fan chromium foar syn uterlik en ferset tsjin corrosie.
②As de wichtichste alloy additief yn steelmaking
③ As ûnmisber tafoegingsmiddel yn it proses fan smelten fan lege koalstofstiel
