I am looking for more detailed information on the pressure-temperature rating of ANSI B16.3 class 150 malleable iron (A197) fittings. I have information stating that they are rated for 300 PSI from -20°F to 150 °F, and 150 PSI @ 366 °F (saturated steam). What is the maximum service temperature that these are permitted to be used at per B16.3?
