ASTM A815 S32205-S Duplex Stainless Steel Concentric Reducer, Buttweld Fittings B16.9

The ASTM A815 S32205-S Duplex Stainless Steel Concentric Reducer is a pipe fitting manufactured in accordance with ASTM A815/A815M standard. This Specification is for Wrought Ferritic, Ferritic/Austenitic, and Martensitic Stainless Steel Piping Fittings. 


It specifically made from duplex stainless steel grade S32205 (2205) with the "S" suffix indicating seamless manufacturing. This reducer features a conical shape with concentric ends, ensuring a symmetrical reduction in pipe diameter while maintaining alignment of the centerline. It is designed for high-pressure and corrosive service applications, leveraging the dual-phase microstructure of duplex stainless steel for enhanced strength, chloride stress corrosion cracking resistance, and corrosion resistance in aggressive environments.

2. Key Adventages

  • The duplex microstructure provides approximately twice the yield strength of standard austenitic stainless steels (e.g., 304/316), allowing for thinner walls and lighter weight fittings while maintaining pressure ratings.
  • Offers outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in environments containing chlorides, acids, and sulfides. Performance exceeds that of 316L.
  • Particularly resistant to chloride-induced stress corrosion cracking, a common failure mode for standard austenitic steels in harsh environments (e.g., offshore, chemical processing).
  • Combines high strength with good toughness and ductility over a wide temperature range, suitable for demanding applications from cryogenic to moderately elevated temperatures.


3. Key Applications

  • Oil & Gas Industry
  • Chemical & Petrochemical Processing
  • Marine & Offshore Engineering
  • Pulp & Paper Industry
  • Pollution Control & Desalination
  • Energy & Power Generation
