Stainless Steel Laser Marking: Industrial Applications and Technical Parameters
Stainless steel laser marking is one of the most commonly used marking methods for part identification and traceability in industrial production. Thanks to fiber laser technology, high-contrast serial number, QR code, DataMatrix code, and logo marking can be performed on stainless steel surfaces. Since laser marking is a non-contact process, it does not create surface deformation and produces long-lasting, permanent marks. This technical guide explains in detail laser marking applications on stainless steel, the laser parameters used, and the performance achieved in production environments.
Stainless Steel Laser Marking Technology
Why is stainless steel marked with a laser?
Stainless steel is a material widely used in industrial production due to its durability and corrosion resistance. Laser marking enables permanent and high-contrast marking on these surfaces.
Fiber laser technology
The most commonly used technology for stainless steel marking is fiber laser systems. The 1064 nm wavelength provides high absorption on metal surfaces.
Marking method
Stainless steel laser marking is generally performed by surface oxidation or micro-engraving methods.
Surface contrast
With laser marking, high-contrast marks in black, gray, or white tones can be created on stainless steel surfaces.
Marking precision
Fiber laser systems can create micro-sized characters and small DataMatrix codes.
Serial number marking
In production lines, stainless steel parts can be identified with serial numbers.
QR code and DataMatrix
For traceability systems, QR codes or DataMatrix codes can be processed with a laser.
Deep engraving
Deep engraving applications can be performed on stainless steel surfaces with a laser.
Surface cleaning
A clean surface before marking improves marking quality.
Industrial application areas
- Automotive parts
- Medical device components
- Machine parts
- Industrial equipment labels
