Sanicro® 28 is a high-alloy multi-purpose austenitic stainless steel for service in highly corrosive conditions. The grade is characterized by:

  • Very high corrosion resistance in strong acids
  • Very good resistance to stress corrosion cracking (SCC) and intergranular corrosion in various environments
  • High resistance to pitting and crevice corrosion
  • Good weldability
