Determinación experimental de la difusividad térmica en acero API5L-X52

We report for first time the thermal diffusivity value of API5L-X52 steel used for manufacturing pipelines. We applied the Photoacoustic technique in a heat transmission configuration at room temperature. We present a comparison of our meassured values and the reported values in literature for other types of steel with a near composition to API5L-X52 steel. The thermal diffusivity value of API5L-X52 steel is 50% less of the pure iron value, a 30% less of 1018 steel value and 12% leess of 1020 steel value.
