september 30, 2019: new metal saw

dci adds coupon wafering

Deep Cryogenics International can now prepare metal test coupons on-site! Our recent addition is a new Kalamazoo 14" precision automated abrasive cut-off saw - allowing us to quickly create damage-free surfaces on scientific research and test metallographic coupons. Gone are the long lead time and rough surface finish of lathe-turned items. We are stocking dozens of superalloys, specialized mining steels, nickel, cast irons and non-ferrous materials for deep cryogenic test and treatment.


september 25, 2019: new R&D capability

dci adds metallographic prep

Our newest purchases - a DE3 diamond engraver and a Pace twin platen grinder polisher for metallographic preparation.

february 2, 2019: new dc MINING research

jack cahn and deep cryo R&D

JACK CAHN and DCI performed deep cryogenic treatment on several mining grade steels last week, both uncoated and with tungsten carbide overlay. Wear, hardness and tensile testing will be performed later this month in Alberta. Results of the study will be published in the fall edition of Canadian Mining Magazine.

Both Vecalloy and 4340 high carbon steel underwent DC treatment. No dimensional change occurs from DCT. Post-DCT annealing eliminates hydrogen embrittlement. Cahn anticipates a reduction in wear effect and an increase in yield strength.
