Saturated steam at standard pressure will be exactly 212F, or 100C.
Superheated steam is steam raised above the saturation temperature, and so
is dry, and could be any temperature above the boiling point at that
Saturated steam under (positive or negative) pressure can boil at other
temperatures, from memory (50 years ago!!) 30psi is 131 degC and 15psi is
Steam in steam engines is generally dry, and is thus to some extent
