Sandvik 2RE69 is a fully austenitic stainless steel with extra low carbon and impurity contents. The grade is characterized by:

  • Excellent resistance to corrosion in ammonium carbamate and nitric acid
  • Excellent resistance to intergranular corrosion
  • High resistance to pitting and crevice corrosion
  • Good weldability

Sandvik 2RE69 has been developed primarily to cope with the severe corrosive conditions existing in the urea industry. The longest service life is so far 35 years, which confirms the optimal properties for the grade Sandvik 2RE69 in urea strippers.
