Ferro Chromium Alloys
Overview:
Ferro Chromium is a critical alloying element used in the production of stainless steel and special steels, offering excellent resistance to oxidation and corrosion. It is an iron-chromium alloy typically containing 50% to 70% chromium by weight.
Form of Ferrochromium | Chromium Content (%) | Carbon Content (%) | Other Elements | Typical Uses |
|---|---|---|---|---|
High Carbon FeCr (HC FeCr) | 60–70% | 6–8% | Si, S, P (minor) | Stainless steel production, cast irons |
Medium Carbon FeCr (MC FeCr) | 60–70% | 0.5–4% | Si, S, P (minor) | Tool steels, high-strength steels |
Low Carbon FeCr (LC FeCr) | 60–70% | <0.5% | Si, S, P (minor) | Corrosion-resistant and high-performance alloys |
Micro Carbon FeCr (MCF FeCr) | 60–70% | <0.1% | Si, S, P (very low) | Superalloys, aerospace-grade materials |
Charge Chrome | 50–60% | 6–8% | High Si (~2%), Al, S | Mass stainless steel production (cost-effective) |
Low Ferrochromium (FeCr low Cr) | 10–45% | Varies | May contain Ni, Mn, etc. | Specialized steel and alloy compositions |
