Also take into account the auxillary parts like drive couplings or belts.
Bjegovic has the right advice - check with the folks who make the equipment.

RE: GREY IRON
Looking at my data most physical values are down to -150°F. There are a few data points at -200°F.
For the irons with high graphite content the tensile and hardness values increase down to -150°F.
The RT Charpy impact values for most irons are halved at -150°F.
I would be very careful in using CI at low temperature as I've seen a vane pump failures in Ppropane service.
