Review on Weldability Prospects of Super Austenitic Stainless Steels

Super Austenitic Stainless Steels (SASS) belongs to the category of austenitic stainless steels which were known for their excellent corrosion resistance when used in structural applications like desalination plants, oil piping systems, heat exchanger equipments which demands high temperature service and harsh environments. Several works on SASS dealt about the corrosion resistance of the material in its normal base metal form. But structural uses needs SASS to be welded with similar or dissimilar materials to fit into the applications. This study aims to present a detailed view on issues related to the weldability of super austenitic stainless steels and the future scope of welding on SASS.
