What Is ASTM A815 S32760?
ASTM A815 S32760 pipe fittings are wrought super duplex stainless steel butt-weld fittings made in accordance with ASTM A815 which is the Standard Specification for Wrought Ferritic, Ferritic/Austenitic, and Martensitic Stainless Steel Piping Fittings. The grade is only specified by its UNS number S32760 in ASTM A815 Table 1 and the trade name "Zeron 100" is not cited anywhere in the ASTM A815 text. This difference is an important procurement risk. If the buyer specifies "Zeron 100 fittings to ASTM A815", he or she should ensure the Mill Test Report (MTR) contains the designation "ASTM A815 WP S32760" and not the trade name. With the UNS designation and ASTM standard reference omitted from the MTR, the product is non-conforming to ASTM A815 requirements, and will be a failure for third-party document review on offshore and process-industry projects.
As part of the Super Duplex Pipe Fittings product family, ASTM A815 S32760 fittings carry a tungsten (W) and copper (Cu) addition that raises the Pitting Resistance Equivalent (PRE) above 41, making them the benchmark grade for the most aggressive chloride and sour-gas environments.

Applications of ASTM A815 S32760 Pipe Fittings
The combination of W and Cu additions, PRE above 41, and solution-annealed microstructure makes ASTM A815 S32760 pipe fittings the grade of choice for the most demanding specification-driven environments.
- Offshore subsea production: seawater injection and subsea manifold specifications
- High-chloride offshore topsides: W + Cu addition provides margin over S32750
- FGD scrubbers: sulfuric acid and chloride resistance in flue gas desulfurization systems
- Acid chloride chemical processes: sulfuric, phosphoric, and hydrochloric acid resistance
- Desalination brine systems: concentrated brine and elevated temperature chloride attack resistance
- Pharmaceutical cleaning circuits: chloride CIP resistance with solution-annealed surface
- Sour gas: NACE MR0175 Part 3 with hardness limit 270 HBW in solution annealed condition

Get Competitive Quote NowFrequently Asked Questions About ASTM A815 S32760 Pipe Fittings
Yes. Zeron 100 is the Rolled Alloys trade name. UNS S32760 is the ASTM A815 designation. Always verify the MTR reads ASTM A815 WP S32760, not just the trade name, to confirm standard compliance.
ASTM A815 Table 1 uses UNS designations only. Zeron 100 is not listed in A815. An MTR citing only the trade name does not satisfy ASTM A815 compliance. UNS S32760 must appear on every conforming certificate.
Solution annealing at 1050-1120 C followed by rapid water quench is required for each fitting individually. Cooling rate must be sufficient to prevent sigma phase formation in the duplex microstructure.
ASME SA815 is technically identical to ASTM A815 and used for ASME pressure vessel code projects. Both ASTM A815 and ASME SA815 can appear on the same MTR for dual-code project requirements.
Yes. S32760 is listed in NACE MR0175 Part 3. Requirements are solution annealed condition and hardness at or below 270 HBW. Verify the project sour service matrix for any additional H2S partial pressure restrictions.
ASME B16.9 applies for NPS 1/2 to 24. MSS-SP-75 applies for large bore NPS 14 to 48. ASME B16.11 applies for socket weld and threaded fittings.
Yes with conditions. It must be solution annealed with hardness at or below 270 HBW per NACE MR0175 Part 3. The buyer must check H2S partial pressure limits in the project-specific sour service matrix before confirming grade selection.
