4130 Chromoly Tubing
-146 Products
|
Chromoly tubing is highly versatile and used for a wide range of applications including automotive, aerospace, bicycling, construction, and firearm projects. 4130 steel tubing offers good strength, weldability, impact and abrasion resistance while also being easy to machine. Because it's stronger than carbon steel, thinner-walled tubing can be used for the same purpose – as in bicycle parts – leading to the part having a lighter weight. 4130 tubing stock is available in full size and custom cut lengths.
