What if the Incans discovered Iron around the time of Virachocha's reign?
They would be successfull until their enemies discover their secret and start manufacturing their own iron tools.
They would, however, be a little better placed to withstand the Spanish (or whomever) when the latter came aconquering.
Especially considering that, contrary to popular belief, steel was more important to the conquistadores than firearms.Having metal piercing/slashing weapons and armor and being experienced fighting with them would give them a great tactical and psychological leg-up when fighting Spanish steel. At very least, the Spanish/Inca death rates in battle would move towards becoming equal (and with the small number of Spanish initially in the Empire, that could be enough to get rid of the first 2-3 waves of conquistadors).
The Conquistadors are still going to have steel were the Incas have only iron, and not nearly as much of it. But, yes, the European advantage, while real, will be much smaller, and probably not large enough.Especially considering that, contrary to popular belief, steel was more important to the conquistadores than firearms.

The problem there as far as I can tell is that the Incans don't have a good reason to stop using Bronze as the primary manufacturing metal, the Andes is one of the few regions where you can find Tin and Copper close together so Bronze is likely the superior option.
I think the creation of steel probably won't take too long - couple hundred years, probably. Ancient cultures found out about it when carbon accidentally got into their smelters, so it seems like some iron smelter is bound to find out about it eventually. Hell, some versions of medieval steel have not yet been replicated (Damascus steel) and it's probably just an accidental discovery.
My understanding is that the Incas used bronze for weapons and tools to some extent, but mainly they used it the same ways that they would have used stone, rather than exploring the unique things they could do with metal. The key advance would probably have been more effective use of bronze, rather than figuring out iron. Actually, the initial shift toward more utilitarian use of metal seems to have been under the Incas, but metal was still primarily used for ornaments/markers of status.
I agree. If your desire is to have an Inca Empire extant in the 1500's that was technologically more able to withstand the conquistadores, it would be better to accelerate and expand the use of bronze metallurgy to the level of early Greece, for example.
