How to Harden Steel Plans

How to Harden Steel Plans

This information is about how to case harden steel.

How many times have you wished that you could put a tough edge on an ordinary nail and drive it through a piece of—say, 1/8-in. steel plate?

Now, using a non-poisonous alloy powder developed by Samuel D. Necamp, known as Hi-Speed-It you can do just that. The powder fuses into the metal and increases the hardness in a matter of seconds.

These plans were scanned from an old magazine and converted to a convenient downloadable digital PDF file format.
