Oversized Multipurpose Oil-Hardening O1 Tool Steel Bars
- Yield Strength: See Table
- Hardness: Rockwell B90 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: See Table
- Specifications Met: ASTM A681
With an oversized thickness, length, and width, these bars can be finished to your exact requirements. Often used for dies, punches, and gauges, O1 tool steel is an oil-hardening material that resists wear and abrasion. These bars, also known as flat stock, are decarb-free for a uniform surface that will consistently accept heat treating.
Precision-ground bars have less stock to remove on the top, bottom, and sides for achieving a finished piece faster.

Oversized Multipurpose Oil-Hardening O1 Tool Steel Rods and Discs
- Yield Strength: 50,000 psi
- Hardness: Rockwell B95 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C62
An oversized diameter allows for finishing to your exact requirements. Often used for dies, punches, and gauges, O1 tool steel is an oil-hardening material that resists wear and abrasion. 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.
