Austenitic chromium nickel molybdenum steel with low carbon content. Resistant to intergranular corrosion in the temperature range up to 400°C (752°F). Does not require post-weld heat treatment. Offers better resistance than l8/8 steels without molybdenum to the attack of acids having a reducing effect, such as diluted sulphuric acid and hydrochloric acid, and to media causing pitting, crevice and stress
corrosion cracking. For optimum resistance, surfaces should be pickled. Cold forming properties are good, the steel is capable of taking a mirror finish.
