Laser etching of steel

Depending on the steel alloy, laser systems can either generate high contrast marks or deep engraving.

Examples of applications includes marking serial numbers on steel tubes, engraving Datamatrix codes on T bars, L or C channels or etching logos on sheets.

Why use a laser for steel engraving & marking?

Fast and reliable technology

Laser engraving of steel allows efficient and rapid marking of an identifier on a steel surface in harsh environments, even if the material temperature is over 800 Celsius degrees.

Robust and permanent markings

Laser marked identifiers on steel surface can usually withstand high temperature annealing, heavy salt spray testing and intense UV exposure.

Low maintenance, no consumables

Laser engraving systems for steel are very low maintenance and consumable free, thanks to the fiber laser based technology.

Repeatable high contrasts marks

Laser engraving of various steel alloys allows the generation a high contrast marks through an optimized process that generates black content and a gray background.

Understanding steel laser marking

Laser marking an identifier on steel can be done with two different processes: annealing or ablating

Laser annealing involves the localised heating of the material. Depending on the temperature attained, a subtopical oxidation of the material takes place. This process maintains the surface roughness of the surface since no material is removed from it. 

Laser ablation is done with higher pulse of energy and leads to the melting, the vaporisation or the removal of material from the surface of the targeted metal in order to change its appearance. This process allows the removal of a precise thickness of metal from the surface.
