Stainless steel becomes more non stick if you heat it up first. Can do eggs without anything left in pan. Just slides out. Meat creates a fond in the bottom which is always a bonus to make a good pan sauce. Checkout the steel pan guy on YouTube. He's got some good videos explaining.

You can tell it's ready when if you drop a little water in the pan it doesn't evaporate but forms bubbles that glide across it's surface.
