Field of application

Automotive industry, construction industry, chemical industry, decorative purposes or architectural elements, food industry, petroleum and petrochemical industry, tank construction, electronic equipment. As delivered, the steel is resistant to intergranular corrosion (e.g. ASTM A262 Pr. E / EN 3651-2); in the welded condition, the resistance can no longer be guaranteed depending on the type of welding and material thickness.
