4130, also known as Chrome Moly (aka chromoly) (short for chromium molybdenum) is a general purpose steel that has been widely used by the motorsports industry for years. Weldability, fabrication, and mild hardenability make it a popular choice in all forms – tube, bar, sheet, and plate.
What is 4130 alloy steel tubing?
4130 Alloy Steel Tubing is Cold Drawn and Seamless. 4130 alloying elements include Chromium and Molybdenum, and for this reason, it is commonly referred to as Chromoly or Chrome Moly.
What is 4130 chromoly used for?
It is widely used in the Aviation, Racing and Cycling Industries because it has an excellent strength to weight ratio, it is very malleable and it is very easy to weld. 4130 Chromoly, Alloy Steel Tube, is resistant to scaling and oxidation and has a clean, smooth finish on both the inside and the outside of the tubing.
