Austenitic chromium nickel molybdenum steel and is produced in many sections including Hollow bar. 316 is resistant to intergranular corrosion in the temperature range up to 300ºC in bar up to 40mm diameter. Owing to its molybdenum content, this steel offers better resistance to acids, having a reducing effect such as diluted sulphuric acid and hydrochloric acid, and to media causing pitting, crevice corrosion and stress corrosion cracking.
