Sanicro® 29 is a high-alloy austenitic stainless steel for service in highly corrosive conditions. Sanicro® 29 was originally developed as an alternative to Sanicro® 28, with improved localized corrosion resistance where the environment contains high chloride concentrations. With the addition of molybdenum the PRE (Pitting Resistance Equivalent) has been increased from ≥38 for Sanicro® 28, to ≥42.

*PRE is defined as, in weight-%, PRE = %Cr + 3.3 x %Mo + 16 x %N

The grade is characterized by:

  • Very good resistance to stress corrosion cracking (SCC)
  • Good resistance to general corrosion and pitting
  • Good weldability

Sanicro® 29 offers a cost-effective solution to corrosion problems compared to high nickel alloys.
