Ion Nitride (Plasma) Services

Ion Nitriding

Ion nitriding, or plasma nitriding, is currently one of the most technologically advanced methods for case hardening of steel components. Effective case depths of up to 0.020-inch are formed in order to provide increased wear, fatigue and corrosion resistance properties. Ion nitriding can be conducted at temperatures lower than those used in conventional heat treat process thereby providing excellent dimensional control and near distortion free results.

Benefits of Ion Nitriding:
  • Extends part/tool life
  • Retention of surface finish
  • No post process machining
  • Increases surface lubricity enhancing material flow in molds/dies
  • Can be used for selective hardening with simple (and reusable) masking techniques

Our ion (plasma) nitriding services can handle parts measuring up to twenty eight inches in length and weighing up to 1,000 pounds. The ion (plasma) nitriding process is applicable to a wide range of products, including gears, bearings & bearing races, shafts, rollers, wear plates, and dies/molds as well as many other parts where service life is often shortened by either galling or sliding abrasive wear problems.

Our process meets high industry standards and serves a wide variety of industries, including mining, molding, and military/defense. Offering quick three day turnaround times, we invite you to contact Mid-South Metallurgical today to learn more about our superior ion (plasma) nitriding capabilities or any of our secondary service options, which include cleaning and straightening.
