Regardless of the type of pan you are using, you will find eggs ate much less likely to stick if you wait for the pan to be hot before you out the eggs in. I don’t know why this is, but if you put cold eggs in a cold pan, they will stick when you cook them.
A little tip - put a small pad of butter on the pan first, let it melt, and then spread it out. The pan will be the perfect temp for the eggs and it’ll make them a bit better.
Also, add a couple tablespoons of milk to the eggs. It will make them smoother and fluffier.
Usually you need hot pan as the water will vaporise and make a vapor layer that prevent sticking
For inox pan, it also avoid that the micro cracks in the metal move and expand during the cooking which tend to trap the food and make it stick a lot
But you should avoid to heat a non-stick pan without food as it can emit toxic fume if it reach a critical temperature
