English translation:What does Case Hardened mean?
Explanation:
The idea behind case hardening is to have two different types of steel at two different points in time. During manufacturing, what you would like is a relatively soft steel that is easy to bend and machine. For a lock's shank, however, a soft steel is not good because it is easy to cut with a metal saw. So after the piece is formed, you harden it to make it very difficult to cut. 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.
