I Forge Iron

Long time lurker looking for steel identification.


Recommended Posts

Sorry, I realized how bad of a description that is after I hit submit. I can snap a picture of the sparks from the grinder when I get to work tomorrow. If I had to go by memory and by the chart in "Metallurgy Made Simple" I would say they were "many fine repeating sprigs" so possibly manganese steel? I think?

Coworker found it sitting on a rock while he was walking around picking up trash, very possible one of the landscapers hit one of the "ornamental" rocks around the driveway. Just seemed too big to be a mower blade, but I do agree it looks like it snapped at a bolt hole. Also: it's nice to meet you frosty and Thomas, I always look forward to your responses in threads and you've unknowingly helped me a lot in my short time (about 9 months) forging.

I have hit lots of rocks and various other hard objects mowing grass, trashed hundreds of blades and have never actually broken one, they all just bend, not saying impossible but I have never seen one break off in the past 16 years.
