Low-carbon ferrochrome [FCrL]
Low-carbon Ferro Chrome
Carefully selected chromium ore and burnt lime are melted in an electric furnace, tapped, and refined out-of-furnace to produce products that meet the customer's needs.
- Trace elements(C,Si,P,S,N,Co,etc.)are controlled by optimizing the type/amount of raw materials and reducing agents, mixing and reduction reaction conditions, casting conditions, etc.
- Products of various sizes suited to the spectific application can be produced by applying blast machinery and powerful crushing equipment.
Feature of products
Special ferrochrome
Special Ferrochrome
We supply various types of unique JFE Mineral special alloys, which are produced utilizing vacuum degassing, nitriding, and induction furnace melting technologies.
- JFE JFE Mineral manufactures carbon-free ferrochrome as an ultra-low-carbon chrome source; produced by a large-scale vacuum furnace process.
- As a nitriding additive for steel, we manufacture nitrided ferrochrome by a large-scale nitriding furnace process.
We also manufacture melt-nitrided ferrochrome by remelting in an induction furnace.
Feature of products
Low-carbon ferrochrome SA [FCrL-SA]
Superalloy Raw Materials
Low-carbon ferrochrome for superalloys (SA) is the culmination of JFE Mineral's outstanding ferrochrome manufacturing technologies.
- Cr component is stabilized at a high level of 68 to 70% by using a combination of raw material treatment technology and electric furnace smelting technology.
- Use of advanced out-of-furnace refining technology makes it possible to control trace elements (C, Si, P, S, Co, N, etc.) to extremely low levels.
- FCrL-SA is a low-cost chrome source that can be used with confidence as a replacement for metallic chrome in superalloys.

MATERIC CHROME (High-purity metallic chrome)
Superalloy Raw Materials
Using a unique manufacturing process, JFE Mineral supplies high purity metallic chrome with purity exceeding 99.5% as a chrome source for superalloys, mainly for use in aircraft.
- High purity products with Si, Al, and S stably reduced to previously-impossible low levels by utilizing electric furnace two-stage refining technology.
- Gaseous components (N, C, O) are stabilized at extremely low levels by a degassing process using a large-scale vacuum furnace.
