Chromium oxide is formed naturally when chromium reacts with oxygen.
Laser etching stainless steel.
Laser engraving stainless steel removes an important protective layer.
Our fiber laser machines can engrave or mark all types of metals including stainless steel aluminum tool steel brass titanium and much more allowing you to create a variety of mark types in no time.
They re all made of elements such as iron nickel carbon and chromium.
Not all laser technologies can be.
Laser engrave your barcodes serial numbers text and logos with an epilog laser machine.
A by effect of the laser interaction with some metals is a physical and chemical reaction called the heat tint effect which results in the change of the metal surface color.
Focusing is a bit tricky due to the bend surface.
Chromium reacts with oxygen and creates an isolating thin layer that prevents the formation of rust on the surface.
This thin protective layer is composed of chromium oxide.
In fact any method that digs markings on the surface deep or shallow will remove this layer.
Lately i have been engraving a lot of hip flasks.
Laser marking stainless steel.
The preferred marking method for stainless steel is laser annealing since it protects the chromium oxide layer on the metal surface.
Afterwards place it into the laser as well as something that helps you to later find the position.
The latter makes up for at least 10 5 of the alloy.
This process is a desired form of oxidation known as.
Due to them being out of stainless steel it works really well.
Laser marking is most often used to mark stainless steel grades 304 and 316 but it can be used to mark any grade.
Start by cleaning it with isopropyl alcohol and mark your focus point.
The color engraving is possible on oxygen hungry materials such as.
Metal laser engraving machines.
Nitrogen assist gas leaves a clean dross free edge with minimal heat affected areas.
Laser cutting stainless steel works with a wide variety of industries.
Stainless steel laser cutting engraving examples.
As a result you get high quality marks and prevent the formation of rust on the.
Engraving etching or annealing many types of stainless steel alloys and grades exist.
