Milwaukee? Ice Hardened? products utilize a proprietary cryogenic hardening process that improves upon traditional heat treat processes.
Unlike surface coatings that wear away, cryogenics harden right to the core by minimizing soft metal (austenite / gamma phase iron) and creating more hard metal (martensite / steel crystalline structure).
The result is a product that is more consistently hard throughout, resulting in life up to 50% longer than the competition.
