LASER MARKING
Stainless Steel Laser Marking Services
In sectors such as transportation, food processing, and heavy industry, identification must be as durable as the component itself. Graphie provides fiber laser marking services dedicated to stainless steel laser marking, delivering permanent, high-contrast identification without compromising material integrity.
Based in La Pocatière, Quebec, we support manufacturers across Canada and the United States with industrial part marking solutions engineered for harsh environments. Our controlled laser marking processes ensure that identification remains legible for the full service life of the product; whether applied to data plates, serial tags, or directly onto stainless steel chassis components.
Marking parameters are documented and repeatable, making this service ideally suited for recurring production programs requiring consistent quality and traceability.
The Superiority of Laser Annealing
Marking stainless steel requires a specific approach to preserve corrosion resistance. Graphie uses laser annealing, a process specifically adapted for stainless steel alloys such as 304 and 316.
Unlike mechanical engraving or deep etching; which removes material and can expose the steel to corrosion; annealing uses a focused laser beam to locally heat the surface. This controlled thermal reaction induces oxidation that turns the surface deep black without removing material.
-
Corrosion Resistance: Because the chromium oxide layer remains intact, the marked area retains its full resistance to rust and oxidation.
-
Surface Integrity: The resulting mark is smooth and flush with the surface, eliminating crevices where bacteria, dirt, or chemicals could accumulate; making it ideal for sanitary environments and outdoor equipment.
-
High Contrast: The process produces a permanent black laser marking with excellent readability against the natural stainless steel finish, superior to traditional stamping or ink-based methods.
Traceability and Serialization for Smart Manufacturing
A label can peel or fade; a laser mark is permanent. Graphie’s industrial laser marking services are designed to support modern traceability and asset management requirements.
-
QR Codes and Data Matrix Codes: We mark high-density 2D codes that remain scannable throughout the product lifecycle, linking physical components to digital records, maintenance logs, or ERP systems.
-
Variable and Serialized Data: Our systems automatically manage dynamic data, including sequential serial numbers and unique UID codes imported directly from Excel or database files; enabling error-free marking across large production volumes.
Typical applications include equipment nameplates, chassis identification, regulatory markings, and permanent asset tags used in transportation and industrial machinery.
Integrated Fabrication and Direct Part Marking
One of Graphie’s key advantages is the ability to integrate laser marking directly into the fabrication workflow. We are not simply a marking shop.
-
One-Stop Process: Stainless steel plates can be laser cut with burr-free edges and immediately laser marked with specifications, warnings, or branding. All under one roof!
-
Direct Part Marking: Identification can be applied directly to stainless steel sub-assemblies we manufacture, eliminating riveted plates or adhesive labels that may loosen or fail over time.
This integration reduces lead times, simplifies logistics, and ensures complete accountability from raw material to finished component.
