Abstract
With the continuous and rapid development of laser
marking technology, the field of applications increases.
In this work, the suitability of laser marking stainless
steel is studied for writing product data on the outer
surface of tubes during production. Generally, thermal
oxidation of a stainless steel surface will deteriorate
its
pitting resistance and, even though corrosive media is
usually inside the tubes, pitting attack from the outside
can cause failures. Three commercial stainless steels,
austenitic 316L (EN 1.4404 / UNS S31600) and duplex
grades LDX 2101 (EN 1.4162 / UNS S32101) and 2304 (EN
1.4362, UNS S32304), were laser marked
using two different parameter settings that resulted in
two different oxide colors. The oxide composition and
thickness were studied with glow discharge optical
emission spectroscopy (GDOES) and the effect of surface
appearance on the pitting corrosion resistance was
determined using ASTM G150. It is shown that the oxide
thickness affects the corrosion performance.
