Applications

Inorys®
The procedure is applicable to all watch exterior parts made in stainless steel :

case-back, case middle and bezel;

crown, pushers, visible screws;

wristbands : buckles and pins, clasps, links, sections.

It even works for movement parts!

Materials suitable for treatment

Inorys®
The treatment is applicable to:

austenetic steels 304/316/904;

strongly allied alloys (Ni, Cr-based);

austeno-ferritic steels;

Phynox® alloys.

Kindly consult us for other alloys.

Inorys® is applied at low temperatures to surfaces with

an immediate underlying structure (up to 50 μm deep).

The quality of the finishing previously performed by the
client (polished, satin-brushed, shotpeened, alternating)

is entirely preserved. This process comprises a structural

hardening phase, called Kolsterisation®.

A cross-sectioned metallographic examina-
tion under an optical microscope reveals
a constant depth of hardening, even in a

blind hole: this picture shows a threaded
hole measuring one millimeter in diameter.
