Ultra-High-Temperature Hardened Multipurpose 4140 Alloy Steel Rods
- Yield Strength: 95,000 psi
- Hardness: Rockwell C26 (Hard)
- Fabrication: See table
- Specifications Met: See table
Made with vanadium, this alloy steel retains its strength at temperatures up to 1100° F. It’s hardened for increased abrasion and impact resistance. Also known as chrome-moly steel, it resists fracturing from repeated stress. These rods are used for a wide range of parts, including gears, shafts, and die holders. This steel has been manufactured to meet ASTM A193 Grade B16, the standard for ultra-high-temperature applications.
Note: Rods may be made from either 4140 or 4142 alloy steel. They are interchangeable in most applications.
