To strengthen steel, you need to use a specific type of heating process known as hardening and tampering. This process can be hazardous. You should always wear face protection and complete the process away from all flammable materials.

Things You Will Need

  • Brazing heart
  • Fire bricks
  • Propane torch
  • Water
  • Emery cloth
  • Metal surface
  1. Surround a brazing heart that is large enough to hold your steel material with fire bricks.

  2. Place the steel on the heart and heat it up with a propane torch.

  3. Remove the steel when it gets red hot and cool it with water. Submerging the steel in water is the best method to use.

  4. Clean the steel using an emery cloth, and place it back on the heart.

  5. Heat it up again more slowly. This time, the steel will turn blue. After the blue color travels the length of the steel, remove it from the brazing heart.

  6. Set the steel on top of another metal surface to slow the cooling process. The more slowly the steel cools, the harder it will become.
