It mostly depends on how much engineering you are doing, and what else you are using your iron for. If you are doing on the order of a mithril or two of engineering a day, and buying plenty of rewards from Conquest Paths, it's easy to run out if you don't have a steady supply. If you are using the promotional alchemy to trade Iron/Wood and colored crystals for Hero Crystals or Guild Coins, you're also going to run out of iron fairly quickly.
