Alloy 310H (UNS S31009) has a carbon content restricted to exclude the lower end of the 310 range. This makes 310H the grade of choice for high temperature applications. This steel has good resistance to oxidation at temperatures of up to 1040°C (1904°F) in intermittent service and 1150°C (2102°F) in continuous service. It is widely used in environments where sulfur dioxide gas is present at high temperatures; however it is recommended that this steel should not be continuously used at 425-860°C (797-1580°F) range due to carbide precipitation.

Heat treatment
These materials cannot be hardened by heat treatment. Solid solution treatment (annealing) is heated to 1040-1150ºC and rapidly cooled for maximum corrosion resistance. Due to the precipitation of long period sigma brittle phase, it is recommended to restore the ductility by solid solution treatment every 1000 hours after use at temperatures above 650ºC
