Laser Etching Stainless Steel Corrosion

Some of the latest results of the material analysis and corrosion tests of the laser treated material are presented.

Laser etching stainless steel corrosion.

After laser etching part numbers we have the instruments passivated for corrosion resistance. 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. This thin protective layer is composed of chromium oxide. Our systems optimize these products by marking them for essential tracking and identification.

Laser engraving stainless steel leads to corrosion. 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. In fact any method that digs markings on the surface deep or shallow will remove this layer.

Laser annealing which creates marks under the surface offers the best resistance to corrosion. Many stainless steel medical tools and devices require passivation to help withstand corrosion and handle numerous autoclave cycles. Laser engraving stainless steel removes an important protective layer. After passivation our laser etching is all but non existent.

Many single and multi use stainless steel medical tools and devices require passivation to help them withstand corrosion and handle numerous autoclave cycles. Possibilities and limitations of steel laser marking are discussed. For high speed marking laser etching is the best process for steel surfaces. Chromium oxide is formed naturally when chromium reacts with oxygen.

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. You can laser mark anodized steel carbon steel die steel stainless steel or any steel alloy. The primary material in use is stainless steel 17 4 ph heat treated to h 900 condition. Because stainless steel tools must avoid corrosion they undergo passivation which is a treatment process consisting of coating metals.

These devices also require laser marking for identification tracking and traceability in accordance with unique device identification udi requirements. At the same time these parts also require laser marking for identification tracking and traceability in accordance with new unique device identification udi requirements.
