<p>The invention relates to a flexible tubular pipe having at least one reinforcing metal armour. The inventive pipe is made from low-carbon steel, i.e. steel with less than 0.16 % carbon, having a predominantly bainitic microstructure and mechanical properties resulting from the addition of micro-alloy elements B, V, Ti, Nb and control of quench hardening conditions.</p> |
