"I’d say, in general, the most common thoughts with salt are to use it for bainitic quenching. If you’re quenching into a bainitic structure, salt has always been the only way to do this," comments Bill. "But what we’re seeing the growth into, and much more activity, is martensitic quench." As you listen, key into the point of salt quenching offering a "green-minded" solution due to recyclability.

Heat Treat Radio: Water in Your Quench with Greg Steiger, Idemitsu

Greg Steiger
Senior Key Account Manager
Idemitsu Lubricants America

Water in the quench tank? How much is too much? What do you do to get rid of it? Is it possible to prevent water from getting into the tank? Greg Steiger of Idemitsu answers these questions and more in this essential episode.

"Our research has shown that basically about 200-250 ppm water, you start to get uneven cooling," Greg Steiger cautions. "When you start getting up to large amounts of water, somewhere around 750 ppm to over 1000 ppm, it becomes a safety issue."

The entire episode gives answers to how to identify, prevent, and remove water in the quench.

Heat Treat Radio: All Things Auto Industry Quenching with Scott MacKenzie

D. Scott MacKenzie, Ph.D
Senior Research -- Metallurgy
Quaker Houghton, Inc.

This interview gets to some nitty gritty details regarding quenching and the shift to electric vehicles. What does the future of heat treating look like for electric vehicles (EVs)? Where is aluminum heat treat fitting in? Listen in to get industry insight on these answers. Scott MacKenzie of Quaker Houghton also explores simulation and modeling, the need for trained metallurgists in our industry, and more broad heat treat considerations.

"The next thing you have to understand is the quenchant itself," Scott MacKenzie advises. "You have to understand the physical properties."
