Oversized Multipurpose Air-Hardening A2 Tool Steel Rods and Discs
- Yield Strength: 55,000 psi
- Hardness: Rockwell B95 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C64
An oversized diameter allows for finishing to your exact requirements. A2 tool steel is more wear resistant than O1 and it keeps a sharper cutting edge. This air-hardening material is widely used for punches, broaches, and dies. These rods and discs are decarb-free for a uniform surface that will consistently accept heat treating.
If you don't see the size you're looking for, please specify a length under additional rod lengths.
