Abstract

ASTM A890 grade 6A super duplex stainless steel (SDSS) is a very popular duplex steel grade. The highly alloyed steel shows precipitation of various intermediate phases at different temperature ranges and among them, sigma is the most deleterious phase. The hard sigma phase accounts for a marked increase in wear resistance. There are, however, very few studies reported on the effect of sigma phase on the roughness of the worn surface. In this work, the material was heated to three different temperatures—850, 1000, and 1100 °C—soaked for 1 hour and later quenched in water. The sigma formation was observed to be the maximum at 850 °C while no trace of sigma could be spotted at 1100 °C. The wear volume was found to be the least for specimen quenched from 850 °C and highest for the sample quenched from 1100 °C. Roughness of the specimen was found to increase in accordance with the sigma content. The sample quenched from 850 °C was noted to have the highest surface roughness.
