Components in the chemical industry, e.g. seperator and heat exchanger parts, in the paper industry, oil and gas production , compressor parts, seawater desalination plants.
Stainless ferritic-austenitic Cr-Ni-Mo-steel with nitrogen addition. High corrosion resistance, especially against stress corrosion cracking in solutions containing chloride. Good strength properties. Resistant to intergranular corrosion in the temperature range up to 300°C. Heat treatment subsequent to welding not necessary. Surface condition for optimum corrosion resistance: pickled, heat treated free from scale or machined.
