Testing tool steel
About a year ago, I bought about 1,500 lbs of "tool" steel rounds ranging
from 1.5" to 6" dia. in 4' average lengths. The guy that bought them originally is dead. We all assumed that the steel was 0-1 and D-2 since he bought them for making dies. Notice the key word in the "Assumed"? One of the techs made a simple die insert assuming the piece was 0-1, torched it to red and quenched it...do it all the time with 0-1 and have few problems. This die was to punch a 1" arbor hole with a 3/8" keyway. It lasted for 20 pieces than broke from the corners of the keyway. He also said it cut a little funny for 0-1. I suggested to remake the die and radius the sharp corners and send it to the heat treater. I also suggested that it was D-2 and sparked it with known samples of 0-1 and D-2...it looked like D-2 to me so the heat treater was told it was D-2. He calls back and says: "This ain't D-2! I ran it twice and it won't harden, I think it's 0-1" He did harden and draw it to 60R as 0-1 but he's still not sure of what it really is. He mentioned it might be 60115??? He also suggested they could send out samples of the different rounds and have them analyzed for about $75 each. I thought I was pretty good at sparking but I'm obviously out of my box. Does this sound like a good price? Is this my best or only option? Mystery steel does me no good, and I have a boat-load of it, it'll last years! |

Testing tool steel
At several dollars per pound for tool steel, you have multiple thousands
dollars of material there. Why not just spend the $75 for a couple of reprsentative samples and get the REAL info?

Testing tool steel
If I had that much - I'd spend the $75 without a blink. Also -
the rounds might be pre-hardened ? My Armor steel is that way - pre-hardened. Martin Martin H.
