First of all, I'm new here, so I apologize in advance if I'm posting in the wrong section. But I've seen a lot of (guesses) thrown out there about what type of steel these are made of, so I found a list of the properties. Now I'm not familiar in this area, so I'll just let someone else answer that. But here's a screenshot of it.

Hope this helps.

Not too helpful without knowing which manufacturer and which type (and how to ID them...) as they come in differing types even from the same manufacturer.

I forgot to I'D the manufacturer, but if it helps, they looked just like these.

As I recall those come in 40 to 60 points C varieties; (your spec is for an upper end version).  *MUCH* better than RR Spikes for items needing hardening; still a bit low for edge holding.

The spec sheet says 56-64 pts. Points Carbon are 1/100th % each. So 56 pts = .56%

Not so hot for edge holding but I like them for hatchets, hawks, etc. as well as jobs that need tough springy  say pry bar, rock chisel, etc.

I made one into a small raising hammer:

Thanks for clearing that up guys. This community is great.

yup, good for hammers

 

Thinking about it on a long drive yesterday got me to thinking about forge welding a couple, few with some 15n20 for pattern and having the coolest: pry, wrecking, speed, etc. bar on ANY job.

Looks pretty close to 9260. I like to use them for tomahawks.
