>From Marks' Standard Handbook for Mechanical Engineers, Table 4.2.17:
(subtract 14.7 psi from the absolute pressure to determine gauge pressure)
Absolute Pressure (psi)         Temp (F)
14.696                                211.99
15                                       213.03
20                                       227.96
25                                       240.08
30                                       250.34
35                                       259.30

You can find better steam tables in Thermodynamics books that will give psi's
between these 5 psi increments (unfortunately someone stole mine from my office
years ago).
