High-Temperature 4140 Alloy Steel Rods
 |
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.
Note: Rods may be made from either 4140 or 4142 alloy steel. They are interchangeable in most applications.
