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
- Fabrication: See table
- Specifications Met: ASTM A681
With an oversized diameter, these rods and discs let you finish to your exact requirements. 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. All have been manufactured to meet ASTM A681 standards for quality and performance.
If you don't see the size you're looking for, please specify a length under additional rod lengths.
