Super Duplex grades with a high Chromium content of 24-26% have been developed to meet specific demands of the oil and gas industry as well as those of the chemical industries. They offer a far superior corrosion resistance and higher strength than standard Duplex grades. We typically supply pipes in grades UNS S32750 and UNS S32760. These pipes can be manufactured as either welded construction or seamless in a full range of sizes and wall thicknesses.
