If you require a tough material with excellent strength, but don't want to
heat treat, consider using Stressproof (1144 Hi Stress) or Fatigue -Proof.
These materials have excellent machining qualities, along with tensile
strength far superior to the other materials. Stressproof and Hi Stress
have a tensile strength of 100,000 PSI, and Fatigue-Proof is greater at
140,000 PSI. All of them are rated at approximately 80% machinability as
compared to 1212 @ 100%. These materials cut very well, without tearing,
and tend to cut better with HSS than carbide, at least from my personal
experience.

I LOVE machining Stressproof. Easy to turn, beautiful finishes with
HSS .

Making sure other people play nice and dont kill each other (and us)
off in job lots is hardly empire building, particularly when you give
them self determination under "play nice" rules.
