Table information is extracted from the Valve—Flanged, Threaded, and Welding End    ASME Standard B16.34 2 .2013. Thes   table  bles must  be used ccordance with the E standard. Theuser is advised that a valve used under the jurisdiction of the ASME Boiler and Pressure Vessel Code, ASME Code for Pressure Piping, or governmental regulations is subject to any limitation of that code or regulation. This includes any maximum temperature limitation for a material or rule governing the use of a material at a low temperature.” 
#. Flanged end ratings terminate at 1000°F.
@. At temperatures over 1000°F, use material only when carbon content is 0.04% or higher.
