Nitriding for your tools & components
Why Nitriding?
Combines excellent wear and lubricating properties
with high load carrying capacity and corrosion resistance
Low temperature process with very little distortion
Process uses NH3 + a Carbon evolving gas, instead
of only NH3 as in conventional gas nitriding
Nitemper® - a patented Ipsen process using 50% NH3
+ 50% Endogas
Adapted batch and continuous furnace technology
NITEMPER AND NITRIDING PROCESS AND EQUIPMENT
NITRIDING-(Nitemper)
Post Nitriding Properties
Wear resistance andself lubrication
Increase in fatigue strength – a characteristic of the diffusion zone, so it remains even in absence of compound layer
High corrosion resistance – because of stable Fe-C-N layer

Structure & Effect of Nitriding method
Nitemper® /Nitriding vs. Salt Bath Nitriding
Cycle time can be as Cycle time should be
Automation is simple
No disposal issues –
Automation is difficult
Salt disposal is a bigissue and may be banned in futureSalt exposes operators tohealth hazards
gas
emission control is easier
Safer operation
Batch Furnace so charge loading/unloading is very easy

long as required short – cleaning problems
Nitemper(R) – A patented Ferritic Nitrocarburising process
Nitrogen and small amounts of Carbon are
transferred to Iron while it is in the ferritic phase
Low temperature –
very small amount
hence Carbon solubility is less so
of Carbon is transferred
