Special characteristics
Austenitic structure.
Antimagnetic structure.
Antimagnetic structure, suitable for low temperatures.
Corrosion resistance
Good.
Corrosion resistant in a natural environment: water, rural, urban and industrial atmosphere.
Medium, by virtue of its coarser porosity the corrosion resistance is in general reduced as compared with stainless steels.
Reservations especially in acid and salty environment.

Very good.
Resistant to corrosion in the natural environment; water, country and city atmospheres without significant chloride or acid concentrations, in food areas and in agricultural food areas.

Main areas of application
Springs for temperatures up to 300°C, tools (knives), sheet metal for vehicles, automotive industry, chemical and food industry.
Chemical, cellulose and paper industry, paint, oil, soap and textile industry, dairies, breweries.
Food industry, agriculture, chemical industry, machine construction, navigation electronics, decorative purposes (kitchen fittings).
