Saturated vs Superheat Steam Conditions - Nationwide …

Superheated steam has a lower density, so lowering the temperature does not revert it back to its original liquid state. Dropping the temperature of saturated steam, however, will revert it back to its old form of water droplets. Superheated steam has more energy and can work harder than saturated steam, but the heat content is much less useful.
