Resistance to Softening : It is the property of a material to come back to its original hardness when it is heated to a certain temperature range for a given time and is then cooled at room temperature.

Hardness at high temperature : The hardness of an electrode material at a given temperature (above room temperature) is a criterion for its service life.
