A multipurpose gas for the metals production industry

Nitrogen is routinely used in iron and steel as well as non-ferrous metals production operations. Its uses and benefits vary across foundries, integrated mills, mini mills, specialty/stainless, and non-ferrous metals processes. Maintenance of proper flow and pressure are critical to reduce costs and help provide consistent results. Our applications engineers can help you determine the optimal flow range and control method to deliver the best results.


Nitrogen can be used in a wide range of applications in all phases of metals production, including:

  • Flotation
  • Refining and stirring
  • Degassing
  • Die cooling
  • Molding and casting
  • Slag splashing
  • Bottom stirring
  • Inerting/shrouding
  • Blast furnace blowdown
  • Post treatment

to provide numerous benefits, such as:

  • Preventing oxidation of the melt/metal surface
  • Extending refractory life
  • Cooling
  • Desulfurization
  • Increasing productivity and yield
