Alloy Steel Round Tube 4130

Alloy Steel Round Tube 4130

4130 chromoly round tubing is highly versatile and used for a wide range of applications including automotive, aerospace, bicycling, construction, and firearm projects. 4130 tubing offers good strength, weldability, impact and abrasion resistance while also being easy to machine. Stronger than carbon steel, the thinner-walled 4130 round tubing can be used for the same purpose, allowing the part to have a lighter weight. We offer 4130 tubing stock in standard and custom-cut lengths. Price and order online or call us for a quote today!

4130 Chromoly Round Tube is stocked in Portland, Toledo, Wallingford, Los Angeles, Dallas and Atlanta.

We also carry 4130 Tubing in Rectangle, Square or Streamline
