4130 Alloy Tubing is commonly referred to as Chromoly, which contains chromium and molybdenum as alloying elements. Chromoly is superior to mild carbon steel based on a strength to weight ratio, making it widely used in applications that require less weight but similar strength. Such as roll cages for race cars, high performance bicycle frames, and fuselages for aircrafts.
