Black marking on stainless steel

Black laser marking is a modern and particularly high-quality method of applying permanent markings to stainless steel. Targeted laser treatment creates a deep black marking on the surface, which is characterised by its high durability and excellent legibility - without any additives or coatings.



Advantages of black laser marking:

Highest contrast: the markings appear jet black and are highly visible from any angle.
Durable & abrasion-resistant: The markings are resistant to chemicals, cleaning and mechanical stress.
Gentle on materials: the corrosion resistance of the stainless steel is completely retained.
Flexible in use: Ideal for logos, serial numbers, QR codes or individual labelling.

Typical areas of application:

Medical technology - tamper-proof and sterile labelling
Food industry - hygienic, residue-free labelling
Mechanical engineering & automotive - permanent component labelling
Design & branding - elegant and high-quality product finishingSustainable & economicalBlack laser marking is contactless, requires no chemicals or consumables and is therefore environmentally friendly and cost-efficient.

Why the use of ultrashort pulse lasers is crucial:

Ultra-short pulse las ers (USP lasers) are used for high-quality black laser marking of stainless steel. These work with extremely short pulse durations in the picosecond or femtosecond range. This results in decisive advantages such as precise, gentle processing, as the ultrashort pulses create practically no heat-affected zone. This prevents material damage, cracks or deformation. Perfect black colouring: USP lasers produce an even, deep black marking through targeted nanostructuring of the surface - without additives or coatings.
Maximum corrosion resistance: As the surface is not melted or damaged, the passive layer of the stainless steel is retained. This is particularly important for applications in medical and food technology.
Maximum durability: The markings are abrasion-resistant, resistant to chemicals and can still be read with high contrast even after countless cleaning or sterilisation processes. The use of ultra-short pulse lasers raises black laser marking to the highest level of quality and safety - ideal for industries where reliability, hygiene and durability are top priorities.
