Steel Laser Marking and Engraving

Laser marking on steel is a process that uses a laser to create a permanent engraving on the surface of the steel.

This process is used to mark steel with information such as the serial number, company logo, or other identifying information.

The marking of metals and especially of steel and stainless steel is very precise and can produce high-quality engravings on the surface of the steel. Furthermore, laser marking can be used on a wide range of steel thicknesses, from a few millimeters to several hundred millimeters. Laser marking on steel is also resistant to wear and corrosion, making it ideal for use in harsh environments or extreme weather conditions.

Fiber lasers have a much longer lifespan than CO2 lasers, meaning they don’t need to be replaced as often. Additionally, fiber lasers emit less heat than CO2 lasers, so they won’t damage the workpiece or burn it over time.

Can stainless steel be laser engraved?

Yes, it is possible to engrave stainless steel with a laser.

Stainless steel is a type of steel that contains chromium, nickel and other elements that make it resistant to corrosion and wear. However, stainless steel can still be engraved with a laser if a suitably powerful laser is used.

The laser power needed to engrave stainless steel depends on the thickness of the steel and the type of surface finish. In general, it is more difficult to engrave stainless steel with a shiny finish than a matte finish, as the shiny finish reflects laser light more.

Stainless Steel Laser Marking Machines

Laser marking on steel and stainless steel is a widely adopted process in various industrial sectors due to its precision and durability. Thanks to advanced technology, the markings created are precise, legible and resistant over time, even in difficult environmental conditions such as exposure to atmospheric agents or wear. Laser marking on these metals, in addition to being used for traceability purposes, is also used for the aesthetic marking of logos and graphics.

A significant advantage of laser marking on stainless steel is its resistance to corrosion. This aspect is particularly crucial for applications in harsh environments, such as the marine or medical sectors. Furthermore, laser marking on stainless steel does not compromise the surface finish of the material, maintaining its properties and aesthetic appearance.

Stainless Steel Laser Engraving Machines

Laser engraving on steel and stainless steel offers high flexibility and customization possibilities. Fiber lasers are particularly well suited for these applications, producing clear, sharp engravings. MOPA lasers, a variant of the fiber laser, allow colored markings to be made on steel and offer the possibility of obtaining black markings on anodized aluminium. This type of laser is characterized by lower heat emissions and greater wavelength efficiency, resulting in high-quality engravings with less risk of damage to the workpiece.

In laser engraving on steel, it is possible to exploit different techniques to obtain various visual effects. Laser annealing, for example, is a common technique in the medical industry for marking stainless steel surgical instruments, where the marking must withstand rigorous testing such as multiple sterilizations. This technique locally heats the metal without removing it, creating a dark, durable mark.

Laser engraving on stainless steel can range from black to different shades of grey, gold and white, depending on the temperature achieved and the type of laser used. This ability to vary shades offers a wide range of options to personalize and distinguish products.

Laser marking and engraving on steel and stainless steel are key processes in several industries, offering precision, durability and a wide range of customization possibilities. These technologies are perfectly suited to industries such as automotive, aerospace, medical and many others, where the quality and durability of markings are essential
