Tool Steel A-2 Drill Rod
A2 tool steel is a 5% chromium medium alloy cold work tool steel possessing sufficient hardenability to be air hardened to 60 Rc surface hardness level with good depth of hardening. This widely used tool steel has low distortion in heat treatment, good machinability, good toughness for severe service, high abrasion resistance, and deep hardening properties in large sections. A2 has a fully spheroidized structure and has exceptionally low inclusion levels. A2 is available in de-carb free rounds, flats and squares, as well as drill rod and ground flat stock.
