Superheated Steam Table — by Pressure and Temperature
Enthalpy, entropy, specific volume and specific heat of superheated steam. Below the saturation line it returns compressed-water properties.

State of the fluid
Superheated steam (Region 2)
Enthalpy (h)
3,052kJ/kg
Details
| Saturation temperature at this pressure | 179.9 °C |
| Degree of superheat | 120.1 K |
| Specific volume (v) | 0.258 m³/kg |
| Density | 3.876 kg/m³ |
| Entropy (s) | 7.125 kJ/(kg·K) |
| Internal energy (u) | 2,794 kJ/kg |
| Specific heat (cp) | 2.141 kJ/(kg·K) |
Assumptions
- Pressure and temperature are given INDEPENDENTLY; this pair determines properties only in a single-phase region.
- Exactly on the saturation line the (p, T) pair does not determine dryness; wet steam needs a quality value.
