While most steels require higher output powers to adequately mark them, certain kinds of steel (with less critical cycle times) can be marked with only 25-watts of laser power. The photo to the left was marked with Synrad's 25-watt Fenix laser marker. On polished surfaces, the mark, although lighter than marks made with a 50W    laser, is totally readable.

With a slightly roughened surface, such as a bead blasted or cast finish, the mark contrast on steel is excellent. Below, a readable 2-D barcode was produced on cast steel. The ¼" square barcode contains 19 characters.
