Superheated steam is steam at any given pressure which is heated to a temperature higher than the temperature of saturated steam. It can not contain water or have water exist at this pressure and resembles a gas. In order to obtain this type of steam, steam is heated to a temperature of 100 °C or higher under normal pressure and has a higher heat transfer capability. The properties of superheated steam are closer to a gas than a vapor. With superheated steam temperature and pressure are independent variables not like saturated steams proportional relationship.
