What Is 10 Bar Vacuum Hardening?

black and white round frame

Our 10 Bar Vacuum Furnace system uses computer-controlled cycles, 12 thermocouple monitoring points, and fluidized bed tempering to produce precise, repeatable results. The process is ideal for die cast tooling, hot form tooling, forging, and precision molds—ensuring through-hardening, optimal metallurgical properties, and minimal dimensional distortion.

Unlike oil quenching or outdated batch ovens, vacuum hardening combines clean, scale-free results with unmatched internal metallurgical performance.

The process ensures complete transformation to tempered martensite while:

  • Reducing stress by utilizing interruptible quench and ramp soak profiles

  • Preventing surface cracking and scaling

  • Enabling better dimensional control

  • Maximum toughness and impact strength

Combined with DYNA-BLUE® coatings, this process can reduce total tooling costs by 50% or more by extending life and reducing post-treatment machining.

Customer Comments

“I used to have to leave extra grind stock on my tools but now I can finish machine closer to finish size which cuts down on machining costs. I also had problems with another heat treater in the past with movement and size change when I had my tools nitrided, but Dynamic solved both these problems.
