Firearm Case Hardening

Deciding what and how to restore your prized firearm can sometimes be overwhelming.  There are a lot of options and levels of restoration.  Often there’s no wrong answer, just what’s right for you and your situation.  Case hardening of metal components is often a topic in these restoration conversations.  This is especially true for older firearms with original case hardening or softer metal components. 

What is case hardening?

Case hardening is a process of metal treatment that hardens the surface of a metal component while keeping the underlying metal layer soft.  It is a heat-treating method that’s been used for centuries. Think of it as a layer of protective armor for the component.  Hardening only the surface of a metal part is key to keeping the part ductile.  Parts that are through-hardened often are very brittle.  Brittle parts usually don’t work well in firearms.

How you restore or refinish a firearm is a personal decision.  We have in-depth conversations with customers all the time about different options and levels of restoration. 

No matter your plans, consider the case-hardening possibilities to enhance the aesthetic look of your metal components while providing some protection to the surface of the metal.
