Alloy Steel 4130 Product Guide Product   | Alloy Steel 4130 Round Tube Tolerances product

4130 chromoly round seamless 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 round seamless tubing stock in standard and custom-cut lengths. Call us for a quote today!

 

We also carry 4130 Tubing in Rectangle, Square or Streamline
