Laser mark on stainless steel

Laser marking on steel is a process that provides very consistent results on different products, according to each client’s needs and with the personalisation that each situation requires.  The great advantage of laser marking is that it is highly adaptable and can make a mark with laser technology with no contact.

Couth’s fibre laser technology is ideal for this kind of material. In this article, we want to share the advantages of fibre laser marking on stainless steel for low- or high-scale production.

Stainless steel, a lifelong product

Steel is an alloy of iron and carbon used in a wide range of industries that require highly resistant parts to withstand wear processes. Moreover, stainless steel is also a carbon and iron alloy with at least 10.5% chrome; this is what provides rust protection.

Laser mark on stainless steel

 It is possible to mark stainless steel surfaces thanks to fibre laser technology.  Fibre laser marking on steel darkens the oxide, thus making a long-lasting mark on the material.

When the metals have some sort of surface treatment (paint, varnish, anodising), the laser mark on the steel eliminates the surface treatment and exposes the metal that rusts, providing a contrast between the mark and the treatment.

Uses of stainless steel and why use laser marking

Stainless steel is an excellent material to provide protection against rusting. It is truly useful, since it protects against the constant chemical products that could eat away at the metal.

In the medical industry, stainless steel guarantees safety and hygiene for the utensils used in the sector. For the automobile industry, stainless steel provides complex and truly long-lasting designs under different durability and usage conditions.


Advantages of laser marking on stainless steel

  • One can obtain permanent marks,which is the aim in using laser marking.
  • It provides a magnificentcontrast when the steel is painted or anodised.
  • The degree of definition for reading 1D and 2D codes is excellent quality.
  • It is possible to engrave alphanumeric codeswith good detail.
  • The laser’s different power levels provide speed to the mark, making a permanent mark.
  • The entire process is very quiet and safe.
  • It is not necessary to useIt is a very low-maintenance technology.
