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 Case Hardened Steel metal stays soft. This gives you a piece of metal that you cannot cut with a saw, but which also does not shatter. Case Hardened Steel is offered by us in various forms and is assured to be of superior quality. Imported from vendors in China, the Case Hardened Steel can be availed from us at very competitive rates.
