At Hai Tech Lasers, Inc., we provide precision industrial laser services to customers across a wide range of industries. One of our core service offerings is laser marking. The process produces permanent markings on a variety of materials, including stainless steel.
Below, we provide an overview of the laser marking process, including what it is, the benefits of using it on stainless steel, and the typical applications of laser marked stainless steel.
Laser marking is a manufacturing process that creates permanent or semi-permanent markings. It is a non-contact, non-subtractive marking method, meaning it does not touch the object directly and does not remove material from the surface, which minimizes the risk of mechanical deformation and structural integrity loss. Instead, it uses a laser to add discolorations to localized areas of the object’s surface in distinct shapes and patterns, which can form text (e.g., serial numbers) or designs (e.g., barcodes).
The main method of laser marking stainless steel at Hai Tech Lasers, Inc. is:
Stain marking. This method involves heating the surface of the object to form an oxide layer. Both the thickness of the oxide layer and the grade of stainless steel affect the color that appears.
Compared to other marking methods, laser marking offers a number of advantages when processing stainless steel, such as:
In the industrial and commercial sectors, stainless steel is one of the most commonly used materials. It finds application in the parts and products of a variety of industries, from aerospace and automotive to medical and mechanical components. Many of these components are processed using laser marking technology to add important information (e.g., barcodes and serial numbers) and/or decorative elements (e.g., graphics and patterns).
