Corrosion of Proton Irradiated 309L Stainless Steel Claddings Fabricated by Directed Energy Deposition

Product Number: 51323-18937-SG

$20.00

The reactor pressure vessel (RPV) is one of the most vital components to nuclear reactor operation. RPVs are made from forged low alloy steel and then typically clad on the inside with austenitic stainless steel (SS) to protect from corrosion. Traditionally, RPV claddings are applied with gas tungsten arc welding or submerged arc welding, though these arc welding processes require the use of a high heat input to achieve this dissimilar metal bond. The high heat input leads to excess residual stress, a large heat-affected zone, and deleterious phase formation, including sigma phase, sulfides, carbides, and martensite at the dissimilar metal boundary.
