Tight-Tolerance High-Strength
Easy-to-Machine 1144 Carbon Steel Rods
- Yield Strength: 100,000 psi
- Hardness: Rockwell C22 (Hard)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Not Rated
- Specifications Met: ASTM A108, ASTM A311
These rods are precision ground and held to a strict straightness tolerance, so they're all set for turning applications in your lathe. Often called Stressproof, they are stress-relieved to minimize warping during machining. Containing more carbon and manganese than other easy-to-machine carbon steels, 1144 offers higher yield strength and hardness, even without further heat treatment. Use it to fabricate parts that require stress resistance.
Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Rotary Shafts
Combine these general purpose drive shafts with gears, sprockets, and bearings to transmit rotary motion. All are turned, precision ground, and polished to meet tight diameter and straightness tolerances. This means these shafts evenly distribute loads, reduce vibration, and improve accuracy and stability.
Stainless steel shafts are more corrosion resistant than steel shafts but more difficult to machine. 316 stainless steel shafts are the most corrosion resistant stainless steel shaft.
