I do agree, modern axle steel would be fine, in the past I have made fabricated Hercus 4 way tool posts from cold rolled bar, machined on an hercus and an old shaper and they did great service.
My old axle had a shoulder where the thread starts. the replacement just washes from the taper the thread root diameter and hopefuly wont break.

Hercus made their lathe and mill spindles from Duraflex S1045. Whether Duraflex is only 1045 grade, I have no idea.
