Tight-Tolerance Multipurpose Oil-Hardening O1 Tool Steel Rods

- Yield Strength: 50,000 psi
- Hardness: Rockwell B90 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment:
Inch sizes: Rockwell C65
Metric sizes: Rockwell C62 - Specifications Met: ASTM A681
Ready for turning in a lathe, these rods are precision ground to a tight diameter tolerance. They’re also known as drill rod. Often used for dies, punches, and gauges, O1 tool steel is an oil-hardening material that resists wear and abrasion.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
Tight-Tolerance Easy-to-Machine W1 Tool Steel Rods

- Yield Strength: 50,000 psi
- Hardness: Rockwell B95 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C65
- Specifications Met: ASTM A686
These rods, also called drill rod, are ground and held to strict diameter and straightness tolerances. They are ready to be turned in a lathe. With lower amounts of alloy elements than other tool steels, W1 offers excellent machinability. This water-hardening material is often used for hammers, files, taps, and reamers. These rods are decarb-free for a uniform surface that will consistently accept heat treating.

High-Strength Fracture- and Wear-Resistant Zirconia Ceramic Rods and Discs

Ideal for applications that must resist bending and wear as well as carry heavy loads, these rods and discs are often used for sleeve bearings and shafts instead of metal. Added yttria gives this material more strength and lowers the chances of cracking from impact compared to standard zirconia, alumina, and silicon nitride ceramic. If cracks do occur, they will not spread, extending the life and reliability of this material. It also means this zirconia blend resists wearing down from rubbing against another part or abrasion from chemical slurries.
Zirconia ceramic resists bending better than alumina and silicon nitride ceramic but does not withstand rapid temperature changes or high temperatures as well as other high-performance ceramics.
