Sandvik Sanicro 31HT, commonly known as Alloy 800HT, is an austenitic nickel-iron-chromium alloy characterized by: high creep strength very good resistance to oxidationgood resistance to combustion gasesvery good resistance to carburizationgood resistance to nitrogen absorption good structural stability at high temperaturesgood weldability The grade can be used at temperatures up to about 1100°C (2010°F). In order to have the best ductility this grade should be used above 700 °C (1290 °F). Thanks to its high nickel content and prescribed maximization of (Ti + Al) content, Sandvik Sanicro 31HT shows extremely little proneness to precipitation of embrittling phases.
