Low-Carbon Steel Rods and Discs
- Yield Strength: See table
- Hardness: See table
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: See table
- Fabrication: See table
- Specifications Met: See table
Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into low-strength fasteners, pins, and axles. You can surface harden this material for added wear resistance. All have been manufactured to meet ASTM standards for quality and performance.
Cold-worked rods and discs have a finished look and quality. The cold-working process gives the steel consistent strength, hardness, and dimensions throughout.
Hot-rolled rods and discs are great for forming and fabricating. The steel undergoes less stress in the finishing process and has a little more give, so you can more easily bend and form it. It does however have a rougher surface finish than cold-worked steel.

Multipurpose 4140 Alloy Steel Rods and Discs
Also known as chrome-moly steel, this versatile alloy steel is used for a wide range of parts, such as gears, axles, shafts, collets, and die holders. It resists fracturing from repeated stress. For added wear resistance, the surface can be hardened with heat treating. These rods and discs have been manufactured to meet ASTM standards for quality and performance.
Note: Rods and discs may be made from either 4140 or 4142 alloy steel. They are interchangeable in most applications.
Cold-worked steel rods and discs have a smooth, polished finish. They also have consistent mechanical properties and highly accurate dimensions.
Hot-rolled steel rods have lower yield strength than cold-worked rods, so they’re easier to shape. They have a rougher surface finish than cold-worked rods, so they are good for applications where you need additional processing.

High-Strength Impact-Resistant Ductile Cast Iron Rods
- Yield Strength: 70,000 psi
- Hardness: Rockwell C20 (Hard)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C55
- Fabrication: Cast
- Specifications Met: ASTM A536
Containing more pearlite and less ferrite, these cast iron rods are stronger and harder than standard ductile cast iron. They are resilient and able to withstand repeated stress without breaking. These rods also absorb vibration, so their finished parts run quieter than those made from steel. Use them to create bushings, gears, and pistons. To increase their wear resistance, you can harden these rods through heat treating. They have been manufactured to meet ASTM standards for quality and performance.

- Hardness: Rockwell B95 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C64
- Fabrication: See table
- Specifications Met: ASTM A681
With an oversized diameter, these rods and discs let you finish to your exact requirements. Made of A2 steel, they are more wear resistant than O1 rods and discs. They also keep a sharper cutting edge. When heat treated for added wear resistance, they don’t require baths or quenching and can be air-hardened. A2 tool steel is widely used for punches, blades, and hammers. These rods and discs are decarb-free, which means any surface flaws created during the manufacturing process have been removed. This makes them more machinable and leads to better results from heat treating or finishing. All have been manufactured to meet ASTM A681 standards for quality and performance.
