The picture in the 6th and 7th rows shows you one of my cam rings and the mating components. The internal geometry of the ring will vary from a 4-lobe to an 8-lobe configuration

Pulling some data from our tech reports about our M2 material, you see the following:

UTS: 119,000 PSI (annealed), 625,000 (heat treated)
Yield Strength: 54,000 PSI (annealed), no HT data
Elongation: 13% (annealed), no HT data
Hardness: 25 HRc (annealed), 65-67 HRc (heat treated, vacuum)
Impact Strength: 42 ft-lbs (annealed), 4 ft-lbs (heat treated)

This data is old (circa '88...meaning well before my time!), and was likely performed on dogbones. Actual part data will likely vary.
 
Are you sure about that 625 ksi number? 425 I'd buy...
