| 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). |
