Asking questions is contributing. You remind those that know, and inform those that don't. It sounds to me like maybe you may be a little bit under cured. I use IP on all iron/steel, and have never had a problem. I would blast it and do the entire process again. You might want to keep a close eye on the part temp in several locations. Thicker areas will not heat as quickly and could be under curing. Remember that almost all powders are 100% overcure. What kind of IP are you using? You might want to check the PH to make sure it's correct, and that there are not too many suspended particles.
