Low-Carbon Steel Rods and Discs
- Yield Strength: See table
- Hardness: See table
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: 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 parts that don’t require high strength, such as fixture clamps, mounting plates, and spacers. This material can be surface hardened with heat treating.

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.

Impact-Resistant Ductile Cast Iron Rods and Discs
- Yield Strength: 55,000 psi
- Hardness: Rockwell C20 (Hard)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C60
- Specifications Met: ASTM A536
Ductile cast iron is strong, resilient, and able to handle repeated stress without breaking. It also absorbs vibration, so finished parts run quieter than those made of steel.

Wear-Resistant Easy-to-Machine Acetal Rods and Discs
- Color: White or Black
- Temperature Range: -20° to 180° F
- Tensile Strength: 9,135-9,700 psi (Good)
- Impact Strength: 1-1.5 ft.-lbs./in. (Poor)
- Hardness: Rockwell R120 (Hard)
- For Use Outdoors: No
- Specifications Met: FDA Compliant 21 CFR 176.170, FDA Compliant 21 CFR 177.2470, NSF/ANSI 51, NSF/ANSI 61, UL 94HB
Made of naturally slippery acetal copolymer, these rods and discs are an economical alternative to Delrin® acetal resin. They offer similar wear resistance and are equally resistant to expanding when exposed to heat and moisture. They can be machined to close tolerances and are often used to make precision gears, bushing, bearings, and rollers.
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.
Borosilicate Glass Rods and Discs
- Color: Clear
- Max. Temperature: 445° F
- Fabrication: Annealed
Also called Pyrex and Schott glass, this glass resists clouding and pitting and is highly chemical and heat resistant. With a low rate of thermal expansion, it stays dimensionally stable during changes in temperature.
