Ipsen TITAN LT Tempering Vacuum Furnace

Bright Tempering: Achieving High-Quality Appearance During Tempering

By Aymeric Goldsteinas and Craig Moller


Cleanliness and efficiency are of the utmost importance when tempering. So what can be done to prevent discoloration? Through customer collaboration, we have evaluated tempering concerns and gathered data resulting in innovative software and equipment improvements that expand industry capabilities.

This paper analyzes what matters most when putting materials through the tempering process. Authors describe how to reduce cycle time while increasing uniformity through the use of both vacuum and convection heating. This paper will also present data collected from tests run on the bright tempering of sensitive alloys such as PH 17-4 (X5CrNiCuNb 16-4), Inconel 718 and 420 stainless steel (X42Cr13) that yielded bright, clean and uniform parts.


Imagine trying to temper your materials above a charcoal or coal forge, or even by fire. From the oldest known example of tempered martensite in 1200 B.C., the process of tempering has remained relatively unchanged over the ages. However, all that is changing. The TITAN® T brings tempering technology into a new age, moving thermal processing forward.

The TITAN T excels in workpiece uniformity and process performance efficiency. Through true vacuum tempering, the furnace provides brighter and cleaner parts. Tempering furnaces are coming out of the dark ages and into a bright future with Ipsen's TITAN T. The increasingly well-known TITAN platform is built using an innovative, flow‐production process that integrates premium components, all developed with the customer in mind. Endurance testing combined with ongoing user feedback allow the TITAN product line to remain agile while setting a standard of excellence. Our controls system is continuously enhanced for usability and precision.
