Sandvik 2RE69 Seamless tube and pipe
Categories: Metal; Ferrous Metal; Austenitic; Ferritic; Stainless Steel

Material Notes: Sandvik 2RE69 is a fully austenitic stainless steel with extra low carbon and impurity contents. The grade is primarily developed in order to cope with the severe corrosive conditions existing in the urea industry. The characteristics of Sandvik 2RE69 are:
  • Excellent resistance to corrosion in ammonium carbamate and nitric acid
  • Excellent resistance to intergranular corrosion
  • High resistance to pitting and crevice corrosion
  • Good weldability
  • Information provided by Sandvik
