DYNA-BLUE®
The Toughest Surface You’ll Never See
Engineered to protect your most valuable tooling, DYNA-BLUE® offers unmatched wear resistance, heat fatigue strength, and corrosion protection—without the drawbacks of traditional coatings.
What Is DYNA-BLUE®?
Advanced surface treatments that protect steel tools from wear, corrosion, and fatigue.
DYNA-BLUE® is a low-temperature ferritic nitrocarburizing treatment designed to create an ultra-hard, corrosion-resistant surface on steel tools and components. Using a proprietary process with over 250 custom-engineered variations, DYNA-BLUE® develops two key layers into the steel itself:
-
A hard compound zone (typically 75+ Rockwell C) for superior wear resistance
-
A nitrogen-enriched diffusion zone for added fatigue and crack resistance
Unlike traditional coatings, DYNA-BLUE® diffuses into the steel—so it won’t flake, chip, or peel. It penetrates internal features, holes, and ribs that line-of-sight methods like chrome, nickel-plating or PVD simply can’t.
How It Works
Each DYNA-BLUE® application is engineered to your steel type and application. Surface hardness, case depth, and cycle times are adjusted to achieve the designed outcome.
DYNA-BLUE® vs. Traditional Coatings
| Feature | DYNA-BLUE® | Ion/Gas/Salt Bath/Nitrading | Chrome Plating |
