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.

Oversized Easy-to-Machine Gray Cast Iron Rods and Discs
- Yield Strength: Not Rated
- Hardness: Rockwell C20 (Hard)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C50
- Specifications Met: ASTM A247
An oversized diameter allows for finishing to your exact requirements. Gray cast iron machines faster with less wear on cutting tools than most types of steel. It also absorbs vibration, so finished parts run quieter than those made of steel. It's often used for gears, pulleys, rollers, and bushings.

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
- 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.

Wear-Resistant Easy-to-Machine Delrin® Acetal Resin Rods and Discs
Because these naturally slippery, wear-resistant rods and discs resist expanding when exposed to heat and moisture, they can be easily machined to close tolerances. They are a good choice for parts that require precision, such as gears, bushings, and bearings. Delrin® acetal resin is also known as acetal homopolymer; it is stronger and stiffer than acetal copolymer.

- Impact Strength: 1.4 ft.-lbs./in. (Poor)
- Hardness: Rockwell R110 (Hard)
- For Use Outdoors: Yes
- Specifications Met: ASTM D5989
An MDS additive provides exceptional wear resistance as well as a self-lubricating surface. Made of cast nylon 6, they’re easier to machine than other MDS-filled nylon rods and discs, plus they are better electrical insulators. Use them to fabricate gears, sprockets, wear strips, and other high-friction parts. This material is comparable to Nylatron and Nycast.
Easy-to-Machine Wear-Resistant Cast Nylon Rods and Discs
- Color: Off-White
- Temperature Range: -20° to 200° F
- Tensile Strength: 10,000 psi (Good)

- Hardness: Rockwell R110-R115 (Hard)
- For Use Outdoors: No
- Specifications Met: ASTM D5989, FDA Compliant 21 CFR 177.1500, UL 94 HB
Because these cast nylon 6 rods and discs are easier to machine than standard nylon 6/6, they’re often made into pulleys, screws, bushings, and bearings. They’re also better electrical insulators. They have a wear-resistant, slippery surface that reduces friction. This material is comparable to Nylatron and Nycast.
Slippery UHMW Polyethylene Rods and Discs
- Color: White
- Temperature Range: -40° to 180° F
- Tensile Strength: 4,350-5,800 psi (Poor)
- Impact Strength: 16.8 ft.-lbs./in. (Excellent)
- Hardness: Durometer 65D-67D (Medium)
- For Use Outdoors: No
Offering a low-friction surface that prevents sticking and binding, these rods and discs are often machined into bushings and bearings. UHMW is impact and wear resistant to handle the scuffs, scrapes, and strikes that other plastics can’t.
