NLE’s Corrosion
Resistant Process passes ASTM F1089-02 (Standard
Test
Method for Corrosion of Surgical Instruments)
on 304, 316, 17-4 and 17-7 stainless steels!
Previously,
a major disadvantage of laser marking or laser
engraving in the medical industry was
in the area of reusable, autoclaveable instruments
made from 17-4 Stainless Steel. The laser process
tended to cause the markings to corrode after
several autoclave cycles. Northeast Laser saw
this as an opportunity to identify the cause
and develop a solution to this challenging problem.
The result (of over a year of research) is NLE’s
proprietary Corrosion Resistant Process, which
has proven effective on 304, 316, 17-4 and 17-7
stainless steels.
The 17-4 stainless steel slugs
in the top photo were marked with NLE's proprietary
Corrosion
Resistant Process, while the slugs in the lower
photo were marked with typical settings. Both
sets of samples were subjected to 50 autoclave
cycles, as well as the ASTM F1089-02 Boil Test
and Copper Sulfate Corrosion Test. The results
are quite dramatic. This proprietary process
survives passivation and passes ASTM F1089-02
(Standard Test Method for Corrosion of Surgical
Instruments) on 304, 316, 17-4 and 17-7 stainless
steels both before and after passivating.
NLE
has been providing this service for over four
years, with outstanding success in the
field. More and more medical device manufacturers
call out NLE’s Corrosion Resistant marking
process, due to our proven results. Give NLE
a call with your medical component application.
We'd be happy to provide you with samples of
our corrosion resistant marking in order for
your company to see how effective our proprietary
process can be.
NLE’s Corrosion Resistant process can
be performed on both flat and curved surfaces.
