Field of application

Construction industry, food industry, pharmaceutical industry, chemical and petrochemical industry, mechanical engineering, aviation, offshore technology, automotive industry, electrical equipment, valve construction. As delivered, the steel is resistant to intergranular corrosion (e.g. ASTM A262 Pr. E / EN 3651-2); in the welded condition, resistance is also guaranteed due to the low C content.
