    Air-Hardening A2 Tool Steel Rods

    Made of A2 steel, they are more wear resistant than O1 rods and discs. They also keep a sharper cutting edge. When heat treated for added wear resistance, they don’t require baths or quenching and can be air-hardened. A2 tool steel is widely used for punches, blades, and hammers. These rods and discs are decarb-free, which means any surface flaws created during the manufacturing process have been removed. This makes them more machinable and leads to better results from heat treating or finishing. With an oversized diameter, these rods and discs let you finish to your exact requirements.
