T45 steel tube specification

Surface Finish

The BS4 T45 tube supplied by ProFormance Metals will always be a black / dark finish and stenciled.

Laboratory tests have proven that by grinding away the surface to increase the applies surface stresses to the composition of the tube. During this process, the opening of the grain structure can occur and therefore increase the chances of fatigue cracks and fractures.

Grinding / Cleanup areas are advised to be kept to a minimum when welding the material.
