High-Purity Ferrochromium Nitride Alloy Powder

Product Specifications

Technical details and manufacturing context for High-Purity Ferrochromium Nitride Alloy Powder

Definition

High-purity ferrochromium nitride alloy powder is a specialized metallurgical additive produced through controlled nitriding processes. It serves as a nitrogen source and chromium carrier in steelmaking, particularly for producing high-strength, corrosion-resistant stainless steels and tool steels. The material enhances hardenability, wear resistance, and high-temperature stability in final metal products. Its controlled particle size distribution ensures uniform dispersion and predictable alloying behavior during industrial melting operations. The powder is characterized by a nitrogen content of 5–8 wt%, chromium content of 60–65 wt%, and a median particle size (D50) of 15–45 μm, with a particle size distribution of D10: 5–15 μm and D90: 45–90 μm. Bulk density ranges from 2.5–3.5 g/cm³, apparent density from 3.0–4.0 g/cm³, and flow rate is ≤30 s/50g. Oxygen content is ≤0.5 ppm, and impurity levels for sulfur, phosphorus, and carbon are ≤0.03%, ≤0.03%, and ≤0.1%, respectively. The melting point is approximately 1600–1700 °C. Sieve analysis indicates +100 mesh ≤1% and -325 mesh ≥90%. The material exhibits relative permeability ≤1.01, making it non-magnetic for specialized uses. These parameters are reference ranges and must be verified for specific applications. The product is intended for use in steelmaking and additive manufacturing, where consistent alloying and low impurity levels are critical. Always confirm model-specific values and applicable standards with the legal manufacturer or supplier.

Working Principle

Nitrogen atoms dissolve into and strengthen the ferrochromium matrix during controlled atmosphere processing, creating stable nitride precipitates that enhance mechanical properties when alloyed into molten steel. The powder's fine particle size and controlled distribution facilitate uniform dispersion and rapid dissolution in molten metal, ensuring consistent nitrogen and chromium delivery. The nitride precipitates contribute to improved hardenability, wear resistance, and high-temperature stability in the final alloy.
