Dodge Posted July 26, 2007 Share Posted July 26, 2007 What kind of steel would number and letter stamps be. These are NOT Harbor Freight stamps. They have (had) 1/2" characters some have 5/8" shank but most are 3/4". They were tossed at work for new legible ones and I couldn't bear to see them thrown away. Figured I could at least make a touch mark with one. Any other ideas?? Quote Link to comment Share on other sites More sharing options...
Robert Mayo Posted July 26, 2007 Share Posted July 26, 2007 I have had a couple made and they where made from O1. Were they made to stamp steel? Are they hardened? Some companies use A2 as well. Bob Quote Link to comment Share on other sites More sharing options...
Jose Gomez Posted July 26, 2007 Share Posted July 26, 2007 Here's a neet tool steel selector guide that might help you figure out what you have now, and will make it easy to figure out what metal to pick for any aplication in the future. www.pvsteel.com/docs/Tsb-093.pdf Enjoy!

Dodge Posted July 26, 2007 Author Share Posted July 26, 2007 Thanks for the link Jose. Yes, Robert. They are hardened, and were used to cold stamp ID #s on mild steel Quote Link to comment Share on other sites More sharing options...
