| Abstract: | We establish that welded joints made by contact butt welding of ferritic-austenitic steel are not susceptible to general, intercrystalline, and pitting corrosion, and the mechanical properties of the joints of pipes comply with the requirements of the ISO API-1104 standard. The base metal and welded joints are subjected to corrosion cracking in a boiling 42% MgCl2 solution and NACE solution. E. O.
