Case Hardening Heat Treatment
High-PrecisionCase Hardening Services for Maximum Surface Strength
A Tough Core With a Rock-Hard Exterior
When you need parts that are impact-resistant on the inside but abrasion-resistant on the outside, case hardening is your go-to solution. It’s a dual-performance heat treatment that gives your components a wear-resistant shell and a ductile core, making them ideal for high-load, high-friction environments.
At Fiesco Precision, we perform case hardening with absolute control and repeatability—because your parts can’t afford to fail.
What Is Case Hardening?
Case hardening is a thermochemical process that hardens only the outer layer (case) of a metal component while maintaining a tough, ductile core. It’s commonly used on low-carbon steels that would otherwise be too soft to handle friction and wear.
We offer various types of case hardening, including:
- Carburizing
- Carbonitriding
- Nitriding (as a subtype)
Each method is selected based on part geometry, application, and desired hardness depth.
Key Benefits of Case Hardening
- Superior wear resistance on the surface
- Strong, ductile interior to resist shock
- Longer component lifespan
- Reduced need for lubrication or replacement
- Improved fatigue strength under dynamic loads
Ideal Applications
Case hardening is perfect for components exposed to sliding contact, shock loads, and repeated motion, such as:
- Gear teeth
- Shafts
- Sprockets
- Pins and bushings
- Clutch parts
- Cam followers

Why Choose Fiesco for Case Hardening?
When surface and core performance must work together, poor treatment isn’t an option. Our state-of-the-art furnaces, advanced controls, and years of metallurgical expertise ensure you get the hardness you need without sacrificing internal strength or dimensional accuracy.
We partner with clients in:
- Automotive manufacturing
- Aerospace
- Agriculture and off-road
- Industrial machinery
Tooling and molds
How It Works at Fiesco
- Part Cleaning and Prep – We clean, degrease, and inspect each component before processing.
- Carburizing/Carbonitriding Stage – Parts are heated in a carbon-rich atmosphere to infuse the outer layer.
- Quenching and Tempering – To lock in hardness while managing internal stress.
- Final Inspection – We measure case depth, hardness profile, and microstructure to meet spec.
