Enter a steam pressure or a temperature and instantly read off the saturation properties — saturation temperature, enthalpy of water (hf), latent heat (hfg), total steam enthalpy (hg) and specific volume. Values are interpolated from standard steam tables.

How to Use the Saturated Steam Table
For saturated steam, pressure and temperature are locked together — fix one and every other property follows. Enter the pressure your boiler or control valve delivers, or the temperature your process needs, and read off the matching steam properties.
Saturation temperature
The saturation temperature (Tsat) is the boiling point of water at the given pressure. Raising the pressure raises Tsat — which is exactly how a steam control valve regulates process temperature.
Enthalpy: hf, hfg and hg
hf is the heat in the saturated water (sensible heat). hfg is the latent heat of evaporation — the energy released when steam condenses, doing useful work in a heat exchanger. hg is the total heat in the steam, where hg = hf + hfg. Latent heat falls as pressure rises.
Specific volume
Specific volume (vg) is the volume occupied by 1 kg of dry saturated steam. It drops sharply as pressure rises — steam at 1 bar occupies about 1.69 m³/kg, but only 0.19 m³/kg at 10 bar. This matters for pipe and valve sizing.
Saturated Steam FAQs
What is a saturated steam table?
A saturated steam table lists steam properties at the boiling point for each pressure — saturation temperature, enthalpy of water (hf), latent heat (hfg), total steam enthalpy (hg) and specific volume. Because saturated steam pressure and temperature are directly linked, one value gives you all the rest.
What is the saturation temperature of steam at 10 bar?
At 10 bar absolute, saturation temperature is about 179.9 °C, latent heat about 2015 kJ/kg and total enthalpy around 2778 kJ/kg. At 10 bar gauge (approximately 11 bar absolute) it is roughly 184 °C.
What is latent heat of steam?
Latent heat (hfg) is the energy needed to turn boiling water into steam at constant pressure and temperature, and the heat released when steam condenses in a heat exchanger. It decreases with pressure: about 2258 kJ/kg at 1 bar, around 2015 kJ/kg at 10 bar.
What is the difference between hf, hfg and hg?
hf is the enthalpy of saturated water (sensible heat), hfg is the latent heat of evaporation, and hg is the total enthalpy of saturated steam, where hg = hf + hfg. In heat transfer it is mainly the latent heat that does the work.
Is the steam table in gauge or absolute pressure?
Standard steam tables use absolute pressure. Convert with: bar absolute = bar gauge + 1.013. This calculator lets you enter either — just tick the gauge checkbox.
Why does steam temperature rise with pressure?
For saturated steam, temperature and pressure are uniquely linked, so raising pressure raises the boiling point and saturation temperature. This is the principle behind controlling process temperature with a steam pressure control valve.
