Chromoly 4130 is a low alloy steel containing chromium, molybdenum, iron, carbon, and other alloying elements. The addition of chromium to steel improves strength and corrosion resistance and the molybdenum increases material toughness. 4130 chromoly tubing also has a smooth interior and exterior finish that resists scaling and oxidation.
Additional Advantages of 4130 Round Tubing
- Excellent strength-to-weight ratio
- High tensile strength, ductility, and toughness
- Lighter and stronger than carbon steel
- Easy to weld, form, and machine
- Ability to case harden using carburization
- Ability to harden using heat treating or work hardening

Chromoly 4130 Round Steel Tubing ApplicationsRound steel tube 4130 provides good weldability without compromising steel abrasion and impact resistance. It is also sturdy yet lightweight for use in applications requiring strength without additional weight. These properties make the material ideal for use in structural applications, including gears, fasteners, and welded tubing.
Some of the common applications for 4130 round tubing include:
- Motorcycle frames
- Aerospace applications
- Motorsport chassis
- Aircraft gas delivery systems
- Bicycle frames
- Racecar roll cages
