2. SANJAY STEEL SYNDICATE Tool Room & Heat Treatment Services 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)

3. Post Nitriding Properties  Wear resistance and self 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  SANJAY STEEL SYNDICATE Tool Room & Heat Treatment Services NITEMPER AND NITRIDING PROCESS AND EQUIPMENT

6. Nitemper® /Nitriding vs. Salt Bath Nitriding  Cycle time can be as  Cycle timeshould be Automation is simple No disposal issues – Automation is difficult Salt disposal is a big issue and may be banned in future Salt exposes operators to health hazards  gasgas emission control is easier   Safer operation Batch Furnace so charge loading/unloading is very easy SALT BATH NITRIDINGNITEMPER/NITRIDING SANJAY STEEL SYNDICATE Tool Room & Heat Treatment Services NITEMPER AND NITRIDING PROCESS AND EQUIPMENT long as required short – cleaning problems  

7. 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 Carbonis transferred SANJAY STEEL SYNDICATE Tool Room & Heat Treatment Services NITEMPER AND NITRIDING PROCESS AND EQUIPMENT
