What are they made of? A relative of mine just scrapped a rototiller and gave me the blades, 16 of them. I haven't had any shop time to play with them, but they look like they'll straighten out pretty easily.
Any input would be appreciated.

It all depends Osbourn. On some, the edges have had hardfacing welded on. On others, not. The main body is probably high carbon spring steel. No idea what classification. Souns like you'll know more when you have shop time to play with them. Good luck.

Since I know who dissassmbled the rototiller, I'm going to try to get the company name from him and give them a call. From what you say, Max, they should make good knives. Thanks.

I had to get new blades for my 20+ years old rototiller (Merry Tiller) a few months ago and I read on some power equipment website that the tines are HT to a Rc of 48. Not sure of the type of steel used, but it has to be pretty damn tough given the working conditions.

John Deere has an article on discs. An interesting test that they do is to drill a 1/2in hole in a disc and then push a 1in steel ball thru the hole. The cracks have to be contained within something like 3in and have a random pattern. They mentioned that they use a couple of different grades of carbon steel, one was 0.8% as I recall, hardened to different levels.
