As both molasses and Evaporust are based on the chelation process, is it not reasonable to assume that Evaporust may also harm hardened steel? On the Evaporust website there is much talk about how safe it is, but no mention of using it on automotive gear cogs or other hardened steel.

Yep, I've wondered the same thing?
By far my sandblaster removes most rust, mainly because it's quick and handy.
