WED Sistemi only uses AISI 304 stainless
steel for all its mechanical components, in
order to make sure their long lifespan and
the watergames’ highest efficiency.
AISI 304 is a non-austenitic steel alloy made up of steel and
several components in different proportions: chrome (18-20%)
and nickel (8-11%). The acronym “AISI” means “American Iron
and Steel Institute” and the full name is AISI 304 - UNI EN
10088 X5 CrNi 18/10W Nr. I.4301.
Non-austenitic stainless steel alloys (so called “high performance
alloys, super-alloys or exotic materials) are compounds
manufactured by using high percentages of binders (more than
50% in weight); it’s basically an extension of traditional austenitic
stainless steel.These alloys were developed to give supplemental
features compared to the traditional alloys when it comes to
rust alveolar and stress strength.
Non-austenitic alloys’ components are chrome (20-27%),
nickel (25-42%) and molybdenum (3-6%). These pretty high
percentages give the alloys higher acid rust strength at the
highest temperature and concentration and crack resistance
due to tenso-corrosion in the presence of chlorine dioxide
The main features are typical for austenitic stainless steel
alloys, but with better results during the welding process.
Common iron and steel alloys are
affected by rust after some time, with
outstanding structural damage as a result
