I am currently working on a project with this stuff. I am finding all kinds of hard spots in this material (during a gundrill cycle, my spindle load will vary anywhere between 5 - 15% in a 9" deep hole....stays at 5% for an inch, climbs to 15%, back down to 5%, ect) Hard spots in the material would be very undesirable in the particular application that this part is for. (A bolt action receiver....hard spots could cause it to grenade)

I am wondering if we just came across a bad lot of material or if it common to see these issues with this Flexor-M

I've ran Flexor a few times, but I've never heard of Flexor M.
The stuff I've machined was just like 4150PHT, so it sounds like you have some bad material if there are random hard spots.

edit: 4150 PHT is 28-32 Rc.
