| Case Carburising Steels |
| |
The idea behind using Case hardening steels is to have the same steel with two different properties for the outer surface and core.
Case hardened steel is usually formed by diffusing carbon and/or nitrogen into the outer layer of the steel at high temperature. The carbon combines with the steel to make it nearly glass-like in its hardness. The core of the metal stays soft. This gives you a piece of metal that you cannot cut with a saw, but also will not shatter. |
