Quantification of Residual Stresses in Ferritic Steels using Low-Transformation-Temperature and Conventional Ferritic Welding Consumables

DOI

F22 steel is widely used in subsea oil transfer components to control flow and defend against well pressure increases. As easily attainable oil deposits have reduced, it is vital to extract oil from deeper subsea reservoirs. This pushes current material to withstand greater pressures, temperatures and corrosion. Hence, requiring the design of new materials to resist greater degradation. A novel hydrogen-resistant HT10 steel was designed to replace F22, although many performance aspects need to be assessed and compared. Welding residual stresses is one critical area, as these stresses are additive with service stress and can cause cracking in welds. Recently, we studied the development of residual stresses in HT10 steel welds using different filler materials. This proposal aims to quantify residual stresses in F22 welds with identical filler materials and provide comparisons with HT10.
