Induction Heating Part 6: Cryogenic Case Hardening
Induction Heating Part 6: Cryogenic Case Hardening In this video I show you how to cryogenically case harden your low carbon steel parts. What you end up with is a material that has a ductile inner core with a hard outer shell. Parts that require impact resistance as well as abrasion resistance are great candidates for case hardening. Gears, Firing pins, Engine Camshafts, Lock Shackles, Security Fasteners, and Self Drilling Screws are all commonly case hardened. The method of case hardening used in the video is also known as carburizing with a cryogenic treatment. Liquid nitrogen is usually used but I used a isopropyl alcohol dry ice bath. Liquid nitrogen would provide even more benefits by converting even more retained austenite to martensite. Also, if you don't mind the darkness of the part after the hardening process, it's best not to polish it for even more rust protection. This process should mainly be used with low carbon and mild steels.

an Engine after Cryo Heat metal treatment
Cryo Heat.com cryogenically treats the metals for longer life by reducing the friction, and cooling thermal Temperatures for greater stability and longer life of all metals. CryoHeat.com treatment is a one time process that improves the entire structure not just the surface,and will not make parts brittle.
