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.

Tight-Tolerance Shock-Resistant S7 Tool Steel Rods

- Yield Strength: 55,000 psi
- Hardness: Rockwell B90 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C58
- Specifications Met: ASTM A681
The diameter on these rods is precision ground while the straightness is held to a strict tolerance. Also known as drill rod, they are ready for turning in a lathe. Often made into chisels, rivets, and punches, S7 tool steel can handle repeated impact without fracturing. It is an air-hardening material.

Oversized Shock-Resistant S7 Tool Steel Bars

- Yield Strength : 55,000psi
- Hardness: Rockwell B90
- Heat Treatable : Yes
- Max. Hardness After Heat Treatment: See Table
- Specifications Met: ASTM A681
Also known as flat stock, these bars have an oversized thickness, length, and width 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.
Precision-ground bars have less stock to remove on the top, bottom, and sides for achieving a finished piece faster.
If you don't see the size you're looking for, please specify a length under additional bar lengths.

Tight-Tolerance Shock-Resistant S7 Tool Steel Bars

- Yield Strength: 55,000 psi
- Hardness: Rockwell B90 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C61
- Specifications Met: ASTM A681
The thickness on these bars is precision ground to a tight tolerance. They're also known as flat stock. Often made into chisels, rivets, and punches, S7 tool steel can handle repeated impact without fracturing. It is an air-hardening material. These bars are decarb-free for a uniform surface that will consistently accept heat treating.
