4130 steel tubing (chromolly) is one of the most widely used in aviation and racing industries because of its weldability and ease of fabrication. 4130 steel is ideal when a strong light weight steel tubing is needed. The weldability of 4130 chromolly steel tubing is excellent. 4130 tube is resistant to scaling and oxidation and has a clean, smooth finish both on the outside and inside of the tubing. Our 4130 tubing is cold drawn and seamless. Motorcycle builders and race car chassis builders alike, use 4130 tubing because of it's outstanding strength, forgoing mild steel wher a thicker wall must be used have equivilant the equivilent strength as the 4130 chromolly steel tubing.
