Nitrex HTS Illinois, USA: Heat Treatment Beyond Nitriding, Vacuum Expertise

Nitrex stands as a world-leading expert in Nitriding technology and heat treatment. However, did you know that our heat treatment facilities also boast extensive expertise in many conventional heat treatments, including vacuum?

As recently highlighted by Steven Sumner, Nitrex’s new HTS Director of Sales, Americas, “I never realized the extent of Nitrex’s vacuum heat-treating capability. This is particularly true at the Aurora, IL facility, located approximately 40 miles west of downtown Chicago.”

MODULAR VACUUM HEATING SYSTEM

Nitrex HTS Illinois - Modular Vacuum Heat Treat System, LPC

Capabilities at this location include a modular vacuum heat treating system that can oil or high-pressure (20 bar) gas quench (HPGQ) components. It features two integral heating chambers with working zones of 1000mm L x 600mm W x 750mm H (39.4” x 23.6” x 29.5”), maximum gross weight limit of 748 kg (1650 pounds), and maximum processing temperature of 1204°C (2200°F).

While this system caters to hardening, tempering, and carbonitriding, it excels in low pressure carburizing (LPC). The benefits of LPC include:

  • Tighter carbon control and case depth tolerances
  • No Intergranular Oxidation (IGO), potentially improving fatigue properties
  • No decarburization
  • Shorter processing cycles at higher carburizing temperature (above 954°C or 1750°F)
  • Reduced distortion with shorter cycles and HPGQ

Components eligible for LPC cover a wide range of conventionally carburized products, including various gears or shafts.

SINGLE CHAMBER VACUUM FURNACES

Additional capabilities include two single-chamber vacuum furnaces:
  • 6 Bar Vacuum Furnace

Working zone: 610mm L x 610mm W x 914mm H (24” x 24” x 36”)
Maximum gross weight limit: 612kg at 1015°C (1,350 pounds at 1850°F)
Maximum processing temperature: 1315.6°C (2400°F)

  • 2 Bar Vacuum Furnace

Working zone: 1219mm L x 1016mm W x 1829mm H (48” x 40” x 72”)
Maximum gross weight limit: 2722kg at 1010°C (6,000 pounds at 1850°F)
Maximum processing temperature: 1315.6°C (2400°F)

These vacuum furnaces are ideally suited for solution annealing and aging of various tool steels (e.g., A series, H series, S series) and stainless steels.
