I always start with the 2 iron, let it hit 2011, then add the nickel, wait for it to turn into invar, then add the 4 more iron, wait for it to hit 2011 again, then toss in the chromium and manganese.
Thats good, but you are talking about the Stainless Steel recipe, and I'm about the Ultimet one, it does not contain iron at all.
I think that's a good recipe for early game, if one happen to find molybdenite and chromite veins. Cobaltite and pentlandite are even more common. IMO searching for small graphite ore or diamond vein for early steel is rather frustrating.
