steel for garden tool in Metallurgy and other enigmas Posted April 10, 2010 Steels similar to your description, and widely used in agricultural tools, are boron low alloyed steels. I suppose that they are hard to find, but I think that are what you re looking for. http://www.zerneri.com/italian/abotab.htm you can see the specs here. It's written in italian, but mostly are numbers.. On the paper they need tempering, but the carbon level is very low and I think they could work even just after the quench. Or you could try to superquench some kind of low carbon steel.
