Nitrided Ferro Chrome (FeCr-N): High-Performance Alloy with Superior Durability
Nitrided Ferro Chrome, also known as Ferro Chrome Nitride or FeCr-N, is an advanced ferroalloy material enriched with nitrides such as CrN, Cr₂N, and Fe₄N, delivering exceptional properties for high-performance applications.
Composition & Manufacturing
This nitrided alloy typically contains chromium (Cr) around 58–65 % and nitrogen (N) between 3 % and 10 %, tailored to client needs for size, composition, and form—whether as lumps, powder, or granules.
Production methods include solid-state nitriding in vacuum or resistance furnaces, creating dense nitrides with strong structural integrity. Liquid nitriding exists but is less common due to elevated temperatures and reduced nitrogen content.
Outstanding Properties
High heat resistance: Suitable for extreme temperatures, FeCr-N maintains stability up to approximately 1600 °C.
Superior corrosion resistance: Enables prolonged service life in aggressive and corrosive environments.
Wear resistance & hardness: Nitride compounds provide excellent surface strength and durability.
Austenite-promoting nitrogen: Nitrogen expands the austenite phase about 30× more than nickel, offering cost-effective ways to enhance steel properties, even reducing reliance on nickel.
Key Applications
FeCr-N is a versatile additive and alloy agent used widely in the production of:
Nitrogen-containing stainless steels, enhancing strength and corrosion properties;
Heat-resistant and alloy steels for high-temperature industrial use;
Specialty steel grades for tooling, wear parts, and challenging environments;
Magnetic or wear-intensive components, benefiting from iron nitride’s magnetic and hardness characteristics.
