4130 Chromoly tube is a steel alloy of chromium and molybdenum that offers strength under pressure for structural applications in aviation, motorsports, and more.
Our laser cut 4130 Chromoly tube is a low alloy steel made of chromium, molybdenum, iron, and carbon that gives the metal a strength-to-weight ratio that’s superior to mild steel. As a structural tube, 4130 Chromoly is tough, ductile, and weldable. While Chromoly tube does have moderate corrosion resistance from a thin Chromium oxide layer, it’s best to treat Chromoly parts with oil, paint, or other surface sealants for long term rust prevention.
Due to 4130 Chromoly steel tube’s fatigue resistance and relatively low weight, it’s a popular choice for framing components in aircraft and automotive applications. Chromoly tube works and plays hard, so you can use it for motorcycle and go-kart parts, too!
We guarantee awesome quality parts. If you’re not 100% happy, we’ll give you a refund or remake on the spot – no questions, no hassle.
Round 4130 chromoly steel tube is available in the following sizes:
The maximum cut length for all tubing is 60″. Square tubes have a minimum length which is equal to the width + .10″.
Laser tube cutting is available for 4130 chromoly round steel tube.
