The Metals handbook(available in better libraries) is a good source 
for information of this type..  In this case they. if I am 
understanding your application, recommend 6F2 or 6G at 341 to 375 HB. 
These are non standard low alloy tool steels with a carbon content of 
nominal 0.55% The closest AISI standard steel would be 4150 but 6150 
or 60 are also similar.  In terms of scrap materials Heavy duty 
vehicle springs are typically of similar composition.
