Hardening Heat Treatment for Metal Parts
Reinforce Your Parts. Reduce Wear. Extend Lifespan.
In industries where durability is non-negotiable, hardening is your first line of defense. Whether you’re manufacturing gears, shafts, or high-friction components, the hardening process dramatically increases surface hardness and wear resistance, making your parts last longer—under pressure, friction, and time.
At Fiesco Precision, we help you build parts that won’t just survive—they’ll thrive in demanding conditions.
What Is Hardening?
Hardening is a heat treatment process where steel or other ferrous metals are heated to a high temperature and then quickly cooled (quenched) using air, oil, or water. This changes the metal’s internal structure (typically forming martensite), significantly increasing hardness without altering the shape of the part.
At Fiesco, we use precision-controlled ovens and quenching systems to ensure consistent results, even on complex geometries or high-performance alloys.
Types of Anodizing Finishes
Applications of Hardening
Our hardening services are ideal for parts that must withstand friction, impact, and continuous motion, such as:
- Transmission shafts
- Gears and gearboxes
- Cutting tools
- Bearings and rollers
- Agricultural and construction equipment parts
Hardening Process Overview
- Material Analysis – We assess the alloy composition to define the best temperature/quenching combo.
- Controlled Heating – Parts are heated to the austenitizing temperature in our precision furnaces.
- Quenching – Rapid cooling locks in hardness.
- Optional Tempering – To relieve internal stress and increase toughness (recommended).
- Final Inspection – Hardness testing and dimensional checks for quality assurance.
