Manganese‑Nitrogen Bricks (Mn‑N Bricks) – A Block‑Form Stable Nitrogen Alloy Additive for High‑Nitrogen Steel Smelting

Manganese‑Nitrogen Bricks are dense block‑shaped nitrogen‑alloying materials manufactured by pressing and sintering manganese nitride as the primary raw material, with nitrogen content stabilized between 10% and 15%. They serve as a key process material for efficiently introducing nitrogen during the smelting of high‑nitrogen steels and corrosion‑resistant alloys in electric arc furnaces, AOD/VOD vessels, and non‑vacuum induction furnaces. The product offers core advantages such as steady nitrogen release, controllable dissolution kinetics, and splash‑free addition, along with characteristics including high block strength, uniform dimensions, and durability during storage and handling. It enables gradual nitrogen dissolution and uniform diffusion in high‑temperature molten baths, significantly improving nitrogen yield in steel melts and preventing composition fluctuations caused by nitrogen escape.

Produced through isostatic pressing and sintering under protective atmospheres, combined with precise porosity control and crystal‑structure optimization, the product exhibits low volatile content, high thermal stability, and absence of harmful impurity precipitation. It effectively reduces smelting fumes, extends furnace lining life, and improves the continuous casting castability of high‑nitrogen steels. It is particularly suitable for high‑end specialty metallurgy applications with stringent requirements for nitrogen content accuracy and process stability, such as duplex stainless steels for marine engineering, wear‑resistant bearing steels, high‑strength fastener steels, and corrosion‑resistant alloys for nuclear power.

We provide specialty steel and high‑end alloy producers with multiple nitrogen‑content gradients, customized dimensions and densities, and full‑process nitrogen‑behavior simulation for Manganese‑Nitrogen Bricks, along with integrated process support services. We are committed to being your core technical partner in achieving large‑scale, stable production of high‑nitrogen steels.
