: Starrett Oil Hardening O1 Tool Steel Flat Stock, Precision Ground, Standard Tolerance, ASTM A681, 4" Width, 1/4" Thick, 18" Length
I am using this steel for blacksmithing so the quality is important and the characteristics are important. It is high quality and it comes clearly labeled with very valuable information about what temperatures are needed to both harden and temper it. Very happy with this purchase. Great quality.
