Full annealing should be performed between 1000 °C and 1150°C for a few minutes. For increased properties cold worked can be aged but conditions should be controlled carefully. info@vascotube.com | imprint Surface Condition Our seamlessly drawn MP35N tubes exhibit a shiny and even surface . Standard roughness values Ra may be as low as 0,4µm. Standard tubing is finished by using polycrystalline diamond dies. The quality of the inner surface may vary with the wall thickness to diameter ratio. Generally the state of the tools and the drawing sequences greatly affect inner surface quality. By applying special diligence roughness values of the inner surface may be even lower than 0,4µm.
