BRINGING STEEL TO LIFE
Engineered for Exceptional Performance
Precision Thermal Processing for Maximum Performance
Optimize your tools and components to reach their full potential. At voestalpine, we combine state-of-the-art technology with decades of metallurgical expertise to deliver heat treatment solutions that ensure superior hardness, toughness, and wear resistance.
Why Heat Treatment Matters
The quality of a tool is only as good as its heat treatment. Even the highest-grade steel cannot perform without the correct thermal cycle.
Our mission is to provide a “One-Stop-Shop” solution from material selection to final hardening, ensuring your components withstand the most demanding industrial environments.
Our Core Services
We offer a comprehensive range of vacuum and conventional heat treatment processes across our global network of service centers.
1. Vacuum Hardening & Tempering
Our high-pressure vacuum hardening (up to 10 bar) ensures clean, oxidation-free surfaces and minimal distortion.
- Benefits: Bright surface finish, controlled cooling, and repeatable results.
- Applications: Cold work steels, hot work dies, and plastic molds.
2. Nitriding & Nitrocarburizing
Increase surface hardness and corrosion resistance without the risk of distortion associated with high-heat processes.
- Plasma Nitriding: Ideal for complex geometries and partial hardening.
- Gas Nitriding: Superior wear protection for high-load components.
3. Specialized Annealing
- Stress Relieving: Crucial after rough machining to ensure dimensional stability.
- Soft Annealing: Improves machinability and prepares the structure for further processing.
4. Sub-Zero / Cryogenic Treatment
By cooling materials to as low as -150°C, we transform retained austenite into martensite, maximizing dimensional stability and wear life for critical precision tools.
Industry-Leading Quality & Lab Services
Quality is not an afterthought; it is engineered into our process. Our facilities are backed by advanced metallurgical laboratories to validate every batch.
