At the same time, it has high mechanical strength and good weldability. Particularly aimed at the chemical, petrochemical and refinery industries, Sandvik SAF 2707 HD has been developed to meet higher industry demands on performance whilst maintaining the reliability and safety of equipment. Sandvik Sanicro 25, for use in ultra- supercritical coal fired steam boilers, is destined for the next generation of power

stations. Designed for reheater and superheater tubes, Sandvik Sanicro 25 is a creep resistant austenitic material that allows for material temperatures up to 700 º C. The increased steam temperature contributes to higher efficiency, lower carbon dioxide emissions and reduced fuel consumption.
