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.

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.

Oversized Shock-Resistant S7 Tool Steel Rods and Discs
- Yield Strength: 50,000 psi
- Hardness: Rockwell B90 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C55
- Specifications Met: ASTM A681
An oversized diameter allows for finishing to your exact requirements. Often made into chisels, rivets, and punches, S7 tool steel can handle repeated impact without fracturing. It is an air-hardening material. 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.

Oversized Wear-Resistant D2 Tool Steel Rods and Discs
- Yield Strength: 50,000 psi
- Hardness: Rockwell B95 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C62
- Specifications Met: ASTM A681
An oversized diameter allows for finishing to your exact requirements. The addition of nickel gives D2 tool steel better wear resistance than A2. This air-hardening material is often used for cutting blades, stamps, and forming 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.
