Tube alloy steel 4130

for the aerospace industry

4130 steel tube is a general-purpose steel product that has been a mainstay of the aerospace sector for many years. The alloy is often referred to as 'chromoly' or 'chrome moly' due to chromium and molybdenum content. 4130 offers good fabricability, is malleable, and weldable, although welding to other carbon steels is not recommended. Heat treatments at the pre and post-weld stage are advisable to avoid cold cracking. The alloy provides good abrasion and impact resistance. Performance 4130 offers greater hardness and strength than standard carbons steel grades and provides a good strength to weight ratio. As the product is stronger than carbon steel, tubing with a thinner wall can be used, which reduces weight. The alloy benefits from widespread use, including bicycle frames, roll cages and aerostructures.
