10-100mm medium low carbon chromium iron alloy

Chromium iron is divided into high carbon chromium iron according to different carbon contents, including charging grade chromium iron (C ≤ 10%), medium carbon chromium iron (C ≤ 4.0%), low-carbon chromium iron (C ≤ 0.5%), and micro carbon chromium iron (C ≤ 0.15%). Commonly used materials include silicon chromium alloy and chromium iron nitride. Ferrochromium is mainly used as an alloy additive in steelmaking, and in the past, it was added during the refining stage of steelmaking. Smelting low-carbon steel grades such as stainless steel requires the use of low and micro carbon ferrochrome, which has led to significant development in refined ferrochrome production. Due to the improvement of steelmaking technology, when producing stainless steel and other steel grades using AOD method (see refining outside the furnace), carbon chromium iron (mainly charging grade chromium iron) is used to load the furnace, so only low and micro carbon chromium iron needs to be added to adjus…
