Inch sizes: Rockwell C25 (Hard)
Metric sizes: Rockwell C19 (Medium) - Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Not Rated
- Fabrication: Cold Drawn
- Specifications Met: ASTM A108, ASTM A311
Made with more carbon and manganese than other easy-to-machine carbon steels, 1144 carbon steel has a higher yield strength and hardness. Also known as Stressproof, these rods are stress-relieved to minimize warping during machining. Use them to fabricate parts that require stress resistance, such as gears, shafts, and bushings. For added wear resistance, these rods can be surface hardened with heat treating. All meet ASTM A108 and ASTM A311 standards for quality and performance.

Hardened Multipurpose 4140 Alloy Steel Hex Bars
- Yield Strength: 105,000 psi
- Hardness: Rockwell C35 (Hard)
- Specifications Met: ASTM A29, ASTM A108, ASTM A193
These hex bars are hardened for increased abrasion and impact resistance. They are also stress relieved to reduce the chance of warping during machining. Also known as chrome-moly steel, this versatile 4140 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.

Hollow Linear Motion Shafts with Material Certification
Keep a material certificate on hand for compliance and quality assurance needs. Certificates include a traceable lot number and material test report. These hollow shafts reduce system weight and allow you to run various media such as electrical wiring, compressed air tubing, coolants, or lubricants through the center. Use them with linear bearings to reduce friction in manual and automated systems, such as those found in packing, machine tool, and material handling operations. They're smooth, hard, and wear resistant. Both the interior and exterior are ground and polished to tight diameter and straightness tolerances.
These shafts are heat treated to relieve internal stresses, which can cause them to warp out of tolerance. All have chamfered ends to remove sharp edges and reduce damage to bearings, housings, and other components during installation.
Surface smoothness—The lower the microinch value, the smoother the finish and the less friction and wear it will cause on the bearing.
