Sanicro® 35 is an alloy combining the best features of a super austenitic stainless steel and a nickel alloy. The grade has excellent corrosion resistance, for service in sea-water applications and other highly corrosive environments.

The grade is characterized by:

  • Excellent resistance to pitting and crevice corrosion
  • Excellent resistance to stress corrosion cracking (SCC)
  • High resistance to general corrosion in acid and caustic environments
  • High resistance to erosion-corrosion
  • Very high mechanical strength
  • Good weldability using nickel alloy consumables

Standards

  • UNS: N08935
  • Compliance with NACE MR0175/ISO 15156-3:2015, (Petroleum, Petrochemical, and Natural Gas Industries - Materials for Use in H2S-Containing Environments in Oil and Gas Production - Part 3: Cracking-Resistant CRAs (Corrosion-Resistant Alloys) and Other Alloys) for type 4a and type 4c materials.
  • Compliance with ANSI/NACE MR0103/ISO 17495-1:2016, (Petroleum, petrochemical and natural gas industries-Metallic materials resistant to sulfide stress cracking in corrosive petroleum refining environments) for highly alloyed austenitic stainless steels and nickel alloys.

Product standards

  • Seamless tube and pipe: ASTM B163

Approvals

  • ASME Code Case 2982. Boiler and Pressure Vessel Code, Section VIII, Division I and II.
  • Pre-approval for Particular Material Appraisal (PMA), TÜV file 1326W043219
