Sandvik Sanicro 31HT is an austenitic nickel-iron-chromium alloy characterized by: high creep strengthvery good resistance to oxidation good resistance to combustion gasesvery good resistance to carburizationgood resistance to nitrogen absorptiongood structural stability at high temperatures good weldability Sandvik Sanicro 31HT can be used at temperatures up to about 1100°C (2010°F). In order to have the best ductility, it should be used above 700 °C (1290 °F). We can also supply a modified version of Sandvik Sanicro 31HT for use in the temperature range between about 550 and 700°C (1020-1290°F). The chemical composition and heat treatment of this version have been adapted for the highest possible creep ductility. Further information on properties is available on request. Sandvik Sanicro 31HT is not generally used under wet corrosive conditions. For this type of environment, manufacturer recommends Sandvik Sanicro 30, which is specially adapted for wet corrosive conditions up to about 550°C (1020°F).
