Abstract
Abstract: Industries from oil and gas segment, which operate in exploration in offshore and deepwater, find in the super duplex stainless steel, a material that present high performance in highly corrosive environments, enabling its use in equipments subjected to critical operating conditions, such as, high pressures, high temperatures and in contact with harsh chemicals. The combination of alloying various elements in these steels provides high corrosion resistance, high strain-hardening coefficient and low thermal conductivity, which reduces machinability and causes the formation of built up edge (BUE) on the tools used to cut these steels. The goal of this work is to develop the best combination of different cutting speeds with other cutting data already defined, such as tool geometry, cutting feed using high pressure coolant jet (70 bar), aiming long tool life with reduction in the formation of built up edge, allied to the lowest surface roughness values possible, in the longitudinal turning of super duplex stainless steel.
