(OP)
I have a 1961 material spec from G.E described as 1.25% Cr, .5% Mo alloy steel hot rolled, annealed any ideas what modern day material call out might be? Where can I find such specs in the future.
Thank you,
Thank you,

This material is common material for elevated temperature service specified by GE for use in their intermediate or high pressure steam turbine casings or stationary hardware.
I would recommend specifying ASTM A 739. This is a material specification titled "Steel Bars, Alloy, Hot-Wrought, for Elevated Temperature or Pressure-Containing Service."
Specify Grade B11.
