20crmnti vs 8620

[JSBCintl]

We have a customer purchasing investment cast valve for recip pump valves in 8620, case hardened to 55-60Rc and wants to consider Chinese 20CrMnTi instead, to the same specs. Does anyone have experience with this material. How does it compare? Recommendations?

Thanks OGMetEng,
I had read that thread, but thanks for responding.
I was looking for information, such as, comparison of harden ability, core hardness, cast ability, cost, corrosion resistance.
Thanks again,
Billy
