Special characteristics

antimagnetic structure
suitable for
low temperatures,
can be used
up to + 700 °C antimagnetic structure

antimagnetic structure
suitable
for low temperatures

Corrosion resistance

good

Resistant to corrosion in the natural environment: water, country and city atmospheres without significant chloride or acid concentrations, in food areas and in agri-
cultural food areas medium

Due to the sulphur
content reservations in
