The Cold Cure
Jack's first Cryotreatment column defines deep cryogenic treatment (DCT) and asks why a low-cost, chemical-free process has stayed on the margins of industry.
By Jack Cahn, Chief Technologist · First published in Cold Facts, Cryogenic Society of America, Vol. 41 No. 2, May 2025
Key points
- DCT is a 36-hour process at −230 °F to −320 °F; shallow cryogenic treatment runs at −60 °F to −176 °F.
- Reported gains: 20–40% longer wear life, 10–20% higher yield strength and 10–20% less corrosion.
- It does not work on every metal every time: results depend on alloy chemistry, how the part was made, prior heat treatment and how the part fails.
- Four barriers: results that vary by material, small chambers that use a lot of liquid nitrogen, no certification or test standards, and a fragmented industry (fewer than 50 stand-alone DCT providers worldwide, plus 750–1,000 heat treaters offering it on the side).
- The column proposes a cryogenic treatment trade group under the Cryogenic Society of America and heat-treat industry umbrella.
This is DCI's summary. The full article, with its figures and references, is in the PDF above.
