In this video, I explain what laser annealing on stainless steel is, how it works, and how to properly anneal stainless steel using a laser. Annealing is different from engraving or etching. Instead of removing material, the laser heats the surface of the stainless steel to change the oxide layer, creating a permanent black mark without cutting into the metal. You’ll learn what is actually happening to the stainless steel during the annealing process. This step-by-step laser annealing tutorial is beginner friendly and designed to help you understand the process, not just copy settings. Whether you’re using an xTool F2, xTool F2 Ultra, IR laser, MOPA fiber laser, or diode laser, this video will help you get consistent black annealing results on stainless steel. If you want professional-looking black marks on stainless steel without engraving depth, this video will teach you the fundamentals of laser annealing so you can dial in your own settings with confidence.
