Technical Data Sheet
BS T45 is a carbon-manganese steel tube supplied in the hardened and tempered condition. It finds many different applications in both the motorsport and aerospace industries due to its high strength to weight ration. T45 is also weldable, but unlike other chome-moly tube grades does not require heat treating after welding.
