Effects of spherodizing on 44xxx steel
Effects of spherodizing on 44xxx steel
(OP)
I've seen a few posts on heat treating various versions of AISI 4xxx steel (4142, 4340 etc.) to achieve very specific tensile and charpy properties. Most of the time we address the quench and temper operations. What about the pre-Q & T ops like process annealing, normalizing, spherodizing?
Does anybody have a feel for what these will do to enhance the mechanical property outcome of a Q & T ?
Thanks in advance for your time.

Normalizing can produce improved results from a subsequent Q & T operation, particularly if the prior thermal/mechanical processing has resulted in a coarse-grained, shperodized, or highly distorted structure. The other processes you mentioned would either be detrimental or have a negligable effect.
