PROCESS
This process is similar to the case hardening, but apart from the gases used in a case hardening treatment, Ammonia gas is added.

ADVANTAGES IN FRONT OF THE CASE HARDENING

• The hardenability of the carbonitrided layer is increased.
• It allows the replacement of high alloy steels by low alloy steels.
• The hardening is less aggressive, so the possible distortions in the parts are minimized.
• It allows greater tempering temperatures.
• High wearing and corrosion resistance.

TYPES OF PARTS

• Screws.
• Fasteners.
• Spherical joint.
• All pieces of case hardering.
