Nitrurizing Heat Treatment Service
Nitrurizing Heat Treatment Services for Superior Hardness and Wear Resistance
What Is Nitrurizing?
Nitrurizing is a thermochemical heat treatment in which nitrogen atoms are diffused into the surface of steel or alloy components. Unlike hardening, this process does not involve quenching, which means it significantly reduces the risk of warping or distortion in precision components.
Nitrurizing forms a hard nitride layer on the surface—perfect for improving wear resistance, corrosion protection, and service life.
Our Process
- Surface Cleaning – Parts are prepped to ensure full nitrogen absorption.
- Controlled Atmosphere Nitrurizing – We use either gas, plasma, or salt bath nitriding methods based on your specs.
- Optional Post-Oxidation – For added corrosion resistance.
- Final Inspection – Microhardness testing and quality assurance before delivery.
Key Benefits of Nitrurizing
- Extreme surface hardness (up to 1200 HV)
- Low-temperature treatment (reduces distortion)
- Improved fatigue strength
- Enhanced corrosion resistance
- Perfect for precision-machined parts
Best Applications for Nitrurizing
This process is especially recommended for parts that must resist wear and maintain dimensional stability, such as:
- Engine crankshafts and camshafts
- Plastic injection mold components
- Hydraulic piston rods
- Gears and spline shafts
- Aerospace fasteners and structural parts
