Why We’re Different
H&M Blacknitride+™, or Ferritic Nitrocarburizing, is the thermochemical that simultaneously diffuses nitrogen and carbon into the surface of ferrous metals. During the process, a two-part surface layer is formed, an outer iron nitride layer with a nitrogen diffusion layer below it. Nitrogen and carbon are absorbed by and diffused into the surface of the metal. Reproducible and uniform layers with a predetermined thickness will be formed on all areas of the metal. This process results in markedly improved surface properties on ferrous metal parts while maintaining dimensional and shape stability. H&M Blacknitride+™ is commonly used as an alternative to high temperature conventional heat treatments such as carburizing and carbonitriding.
