Outperform with Precision, Consistency, and Cleanliness
Heat treating is a cornerstone of modern manufacturing, enabling metal components to meet demanding performance, durability, and hardness requirements. Among the various methods available, vacuum heat treating stands out for its ability to deliver clean, consistent, and efficient results—especially when paired with Nitrex’s advanced furnace technology.
Whether you’re in aerospace, automotive, tool & die, or medical device manufacturing, Nitrex Vacuum Hardening Furnaces are engineered to deliver exceptional outcomes across the board.
What Is Vacuum Heat Treating?
Vacuum heat treating involves heating metal parts in a low-pressure environment, which eliminates atmospheric gases like oxygen and nitrogen. This absence of contaminants prevents oxidation, discoloration, and decarburization, resulting in parts with a cleaner finish, tighter tolerances, and more consistent mechanical properties.
Why Vacuum Hardening?
- Minimized oxidation for a brighter, scale-free surface
- Improved hardness and strength
- Reduced distortion through precise thermal control
- Repeatable outcomes with consistent temperature uniformity
