Stainless Steel Marking… Stainless steel can be marked with a laser for a wide variety of purposes. Commonly stainless steel items are used for promotional goods, such as pens as well as in the trophy and awards market. Stainless steel and tool steel are often used in industrial settings for tools, tool bits and as rugged long lasting machine data plates. If you are marking stainless steel and other uncoated materials, the surface must first be treated with a very safe chemical that promotes an extremely dark contrast.
