1) Remark: Austenitic steel for pressure vessels according to AD 2000 W2, for pressure equipment according to directive 2014/68/EU and for nuclear engineering. The steel is resistant to intercrystalline corrosion both in the delivery condition and the welded condition without heat treatment up to 400 °C and very good resistant to crevice corrosion and pitting.
