Sandvik 2RK65™ is a high-alloy austenitic stainless steel intended for use under severe corrosive conditions within the process industry. The grade is characterized by:

  • Very good resistance to attacks in acidic environments, e.g. sulfuric, phosphoric and acetic acid
  • Very good resistance to pitting in neutral chloride-bearing solutions
  • Much better resistance to crevice corrosion than steels of the ASTM 304 and ASTM 316 types
  • Very good resistance to stress corrosion cracking
  • Good weldability
