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.

High-Pressure Brass Threaded Pipe Nipples and Pipe with Sealant
Not only does this pipe have the strength to handle high-pressure applications, the threads have a sealant applied for extra protection against leaks. Pipe is brass for good corrosion resistance.
Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.
