What Is CHROMOLY TUBING?
CHROMOLY TUBING are chromoly tube products for fabricated chassis, roll cages, suspension links, control arms, protective frames, and other structures where tube outside diameter, wall thickness, length, weld procedure, and surrounding geometry must be designed together. The tubing is a structural member rather than a complete joint; pair it with suitable tube adapters, rod ends, or clevises and validate the finished assembly.
Typical Applications
Applications for CHROMOLY TUBING
Suspension and Control-Arm Builds
Tubing provides the structural member for custom control arms, radius rods, and linkage assemblies when paired with correctly selected tube adapters and rod ends. Verify cut length and end alignment before welding.
Motorsport and Specialty Equipment
Precision tubing supports weight-conscious vehicle and equipment fabrication. Material certification, welding qualification, corrosion protection, and inspection should follow the project requirements.
Agricultural Fabrication
Suitable for fabricated agricultural machine structures, linkages, and brackets that need strong, cut-to-length steel tube supply.
Industrial Frames and Fixtures
A practical solution for machine frames, fixtures, and structural weldments where consistent outside diameter and wall thickness are required.
OEM Tube Supply Programs
Well suited to OEM projects needing repeat tube dimensions, controlled cut lengths, and project-based special size support.
Product FAQ
Frequently Asked Questions
What is chromoly tubing commonly used for?
Chromoly tubing is commonly used for chassis fabrication, suspension links, steering assemblies, roll cages, and other high-strength tubular structures.
What material is used in this tubing series?
This series uses 4130 chromoly steel. Other materials such as 4140 and 4340 may also be available for project-based requirements.
Are these tubes cut to length?
Yes. The series is supplied in cut-to-length ranges shown in the size chart, helping simplify fabrication planning and stock control.
How do I choose the correct chromoly tubing size?
Choose based on tubing outside diameter, wall thickness, required cut length range, and target weight range for the application.
Can custom sizes or special lengths be supplied?
Yes. Special sizes are available. Contact us with your required outside diameter, wall thickness, and target cut length for review.
Why is 4130 chromoly used for fabrication tubing?
4130 chromoly offers a strong balance of weldability, strength, and structural reliability, making it a common choice for performance and industrial tube fabrication.
