If they're set deep enough in the soil, they'll be in place for many years to remain. If, however, the steel posts are being used for security fencing, the idea of sinking them into concrete to give them additional strength could be an excellent idea.

Tips

If you're planning to use the steel fence posts then you must ensure that it's galvanized. Galvanization is a procedure that covers the metal with an anti-oxidant that stops the oxidization which can cause the formation of rust. Once the metal is treated (usually before purchasing) you will never need to deal with it ever again. It is not like wood, which must be stained and treated frequently to prevent drying out, rotting, or breaking into pieces.
