Should I Case Harden Shredder Teeth?

Had an interesting thought.

If you can heat mild steel in a carbon pack and have it absorb carbon, what would happen if you added chromium powder with the carbon?

Is it possible to create a stainless surface layer that way?

I have a dual burner forge setup with 100lbs propane tank. I could use the 2 burners + extra charcoal on top of the container with forge blower blasting air onto the coals.

Kasenit, Try eBay

about 1650 deg, the length of time you heat soak makes a difference.

have no idea why they stopped making it, so be safe and don't breath it. we did use it decades ago in high school.

I don't think chrome will be absorbed into the mild steel.

I know you are committed to your design because you have invest so much time into it, but sometime backing up and thinking about it is good.
Here is a video of a bone grinder restore, from back in the day when they needed this stuff. This is an easy thing to construct out of steel. The replaceable cutting tips can be made out of good steel and the rest plain mild stock.
This would also grind meat as well.

I think Gerry is on to something here. What if you drilled/tapped for replaceable carbide tips?
