Composition Of Ferrochrome Powder

High carbon ferrochrome (carbon content is 4~8%), medium carbon ferrochrome (carbon content is 0.5~4%), low carbon ferrochrome (carbon content is 0.15~0.50%), micro carbon ferrochrome (carbon content is 0.06%), ultra carbon ferrochrome (carbon content is less than 0.03%), metallic chromium, silicon chromium alloy ferrochrome: The ferroalloy composed of chromium and iron is considered by the ferrochrome powder manufacturers to be the primary alloy additive for steelmaking. Training chromite chromite with general pleading Cr2O340 ~ 50%, chromium and iron ratio more than 2.8. In recent years, many production of 50% chromium "discharge grade chromium iron", with Cr2O3 and chromium to iron ratio is low ore.

Ferrochrome is divided into high carbon ferrochrome according to different carbon content, including discharge grade ferrochrome (C≦10%), medium carbon ferrochrome (C≦ 4.0%), low carbon ferrochrome (C≦ 0.5%), micro-carbon ferrochrome (C≦ 0.15%) etc. Common silicon chromium alloy, ferrochrome nitride and so on.
