Heat Treatment and Testing Requirements per ASTM A815
Every ASTM A815 S32750 pipe fittings unit undergoes rigorous thermal processing. Solution annealing is performed at temperatures between 1040 and 1100 degrees Celsius, followed by a rapid water quench. This prevents the formation of intermetallic phases like sigma, which can embrittle the material. We conduct ferrite content verification per ISO 17781 to ensure a balance of 35 to 65 percent. Additionally, we provide Charpy V notch impact testing at minus 40 degrees Celsius and 100 percent hydrostatic testing when specified.
Applications of ASTM A815 S32750 Fittings
These fittings are primarily used where corrosion resistance and high yield strength are non negotiable.
- Offshore Oil and Gas: Subsea pipelines and manifolds.
- Desalination Plants: High chloride water handling.
- Chemical Processing: Handling organic and inorganic acids.
- FGD Scrubbers: Flue gas desulfurization in power plants.

ASTM A815 is the standard for wrought ferritic and austenitic stainless steel pipe fittings. It covers duplex and super duplex grades using WP or SR classes for pressure ratings under ASME B16.9 and MSS-SP-75.
WP class is standard wall with full burst test factors. SR class stands for schedule reduced, matching pipe wall thickness but offering a lower pressure rating. WP is the preferred standard for high-pressure process piping.
It covers duplex grades like S31803 and S32205, super duplex grades S32750 and S32760, and 6-moly grades like S31254. Each grade is listed in Table 1 of the ASTM A815 specification.
S32750 fittings must undergo solution annealing at 1040-1100°C followed by a rapid water quench. This ensures proper phase balance and prevents brittle intermetallic phases like sigma.
Required properties include a minimum tensile strength of 795 MPa, yield strength of 550 MPa, 15% elongation, and a maximum hardness of 310 HBW.
Yes, they are compliant if solution annealed and hardness is below 310 HBW. These fittings are widely used in offshore sour oil and gas applications as permitted by NACE MR0175 Part 3.
S32750 is standard Super Duplex 2507. S32760, also known as Zeron 100, includes tungsten and copper for enhanced resistance in specific aggressive acidic environments. Both are covered under A815.
Markings must include the manufacturer mark, ASTM A815, UNS grade, class (WP or SR), heat number, and size/schedule. This ensures full material traceability for the user.
