Typically carbon steel isn't used above 800 or 900 deg because you're
starting into the creep range. There are also some metallurgical
changes that take place in addition to alteration of properties
attained by heat treatment. I did some checking around in ASME/ASTM
material specs and didn't find anything like design properties, I
expect because the mechanical properties vary so much with cold work
and thermal treatment.
Your best bet is likely to be the ASM Metals Handbook, but don't
expect design properties--_Metals Handbook_ generally addresses
metallurgy, including typical mechanical properties. There are ASTM
specs for carbon steel bars with room temperature mechanical
properties in various conditions that might allow you to infer high
temperature behavior from the ASME Code allowables, but you'll have
to do some digging.
You haven't mentioned welding, but it's never a good idea with 1045,
and an even worse idea for machinery.
