HTG / HI TecMetal Group Ohio NEW Vacuum Nitriding Furnace - Exceptional Metal Heat Treating Services

Our latest HTG furnace is a horizontal, front-loading furnace meeting Nadcap AMS 2750/E Class 2

The technical “nitty-gritty” follows for those of you who are intrigued! (Aren’t you all?)

  • Nitriding
  • Nitrocarburizing
  • Ferritic Nitrocarburizing (FNC)
  • Tempering
  • Stress Relieving
  • Pre Ox
  • Post Ox

The white layer of the process influences the properties noted below:

  • Wear resistance
  • Surface hardness
  • Yield strength
  • Fatigue Strength
  • Tribological characteristics
  • Corrosion resistance
  • Surface finish
  • Aesthetic finish
  • Dimensional control
  • Alternative to hard chromium plating
  • Weight reduction
  • Cost reduction

Nitriding FNC treatment of steel and cast irons is carried out in the temperature range of 590 °C (1094 °F) -740 °C (1364 °F) using a gaseous nitrogen and carbon bearing atmosphere.

The treatments develop iron nitride surface compound layers between 5µm (≈.0002”) – 50 µm thick (≈.002”), supported by a nitrogen carbon rich diffusion zone in the substrate. By choice of treatment temperature, time and nitrogen potential of atmosphere, the microstructure, composition and hardness of the compound layer and the sub-surface diffusion zone are controlled. An innovative oxidation technique, combined with specially formulated aqueous quenchant and organic sealant are incorporated, depending on the engineering requirements of a specific application.

Our newest furnace is equipped with an advanced control system to assure process accuracy and ratability. The 48” wide x 72” long x 4” high work envelope will handle loads up to 7,000 pounds.

This furnace provides HI TecMetal Group the ability to shorten customer turnaround times while providing the same superior quality of product that HTG customers have come to appreciate. As our customers grow so do we.

We have decades of experience in all phases of heat treating and metal joining. We also have a broad array of furnaces and treatment techniques ensuring we can treat parts of a wide range of sizes and shapes.
