Laser Etching Stainless Steel Corrosion

Laser marking of stainless steel using the pulsed fiber laser spi g3 is described in the contribution.

Laser etching stainless steel corrosion.

If we laser etch before passivation the area of laser etch corrodes after autoclaving. You can laser mark anodized steel carbon steel die steel stainless steel or any steel alloy. Laser engraving should be used to get the most resistant marks. For high speed marking laser etching is the best process for steel surfaces.

The conclusion drawn for their study was the surface finishing of stainless. Evaluated the influence of the laser marking parameters the specifically pulse energy and engraving rate on the corrosion resistance of astm f139 austenitic stainless steel laser marked surface by the use of yag laser beam using of electrochemical methods. There is a growing need to apply identification informational and logo marks to stainless steel devices and products and these marks must meet several strict criteria which largely preclude the use of traditional non laser techniques such as printing or engraving. Chromium oxide is formed naturally when chromium reacts with oxygen.

Because stainless steel tools must avoid corrosion they undergo passivation which is a treatment process consisting of coating metals. Laser engraving stainless steel removes an important protective layer. These devices also require laser marking for identification tracking and traceability in accordance with unique device identification udi requirements. At tykma electrox our laser systems are adept at corrosion resistant laser engraving for use on various single and multi use stainless steel tools and equipment.

Laser engraving stainless steel leads to corrosion. Many single and multi use stainless steel medical tools and devices require passivation to help them withstand corrosion and handle numerous autoclave cycles. At the same time these parts also require laser marking for identification tracking and traceability in accordance with new unique device identification udi requirements. Many stainless steel medical tools and devices require passivation to help withstand corrosion and handle numerous autoclave cycles.

Possibilities and limitations of steel laser marking are discussed. This thin protective layer is composed of chromium oxide. Our systems optimize these products by marking them for essential tracking and identification. Laser annealing which creates marks under the surface offers the best resistance to corrosion.

The primary material in use is stainless steel 17 4 ph heat treated to h 900 condition. After laser etching part numbers we have the instruments passivated for corrosion resistance.
