Material and Heat Treat advice needed for extreme ATV CV Joint.
(OP)
Looking for input on selection of material and heat treat for components in a Rzeppa style two fixed joints with plunging spline CV axle. The design is for an extreme ATV with high angle axles over 30 degrees and large aggressive mud tires. The goal is to design the "ultimate" ATV axle. Intend to use either 4340 or 300M or a combination of the two on the various components: shaft, cup, cage, and race. Heat treats considered:
1) 300M through hardened to 42-47Rc and induction to 53-60Rc
2) 300M through hardened to 52Rc
3) 4340 through hardened to 35Rc and induction hardened to 52Rc
4) 4340 through hardened to 42Rc
Any advice on applying these heat treatments to these components for this application. Open to any suggestions.

Thanks again for help with the "art" project. I tried to do my homework before posting. I came up with these numbers by studying this forum and other reference material.
