For FFL firearm and knife blade makers, our rack salt-to-salt thermal processing is a proven winner.

The process ensures: Superior microstructure with minimal distortion, Scale-free, oxidation-free surfaces, and sticking to your tight tolerances, cutting down on rework and rejects. When paired with our dedicated packaging team and drop-shipping services, customers get the complete package—literally. We’ll keep your parts protected, organized, and delivered exactly where you need them, so you can spend more time building and less time worrying about timelines and logistics.

“Our staff takes enormous pride in finishing jobs right,” said Steve Kowalski, President of Kowalski Heat Treating. “The combination of salt bath processing and our hands-on packaging team means manufacturers can trust us to deliver parts that look great, perform even better, and arrive ready to assemble. That’s how we help our customers win on the shop floor.”
