Description
ASTM A240 F904L Slip On Flat Face Flange AWWA C207 Table2 Class D Meets US water standards
ASTM A240 is a standard specification from the American Society for Testing and Materials (ASTM) for chromium and chromium-nickel stainless steel plates, sheets, and strips used in pressure vessels and general applications.
904L, a high-alloy austenitic stainless steel, is renowned for its excellent corrosion resistance, particularly to sulfuric acid, phosphoric acid, and chloride-containing media. Its key alloying elements are high chromium, nickel, molybdenum, and copper content. This flange also conforms to AWWA C207 and meets the Water Works Association's "Steel Pipe Flanges" standard. It is recognized by the North American water industry and many general industries.
In the AWWA C207 standard, the default face type for Class D flanges is usually flat-face aligned, but it can also be specified as fully flat.

Mechanical Properties (ASTM A240 F904L)
Property Requirement Note
Tensile Strength, min 71 ksi (490 MPa)
Yield Strength (0.2% offset), min 31 ksi (220 MPa)
Elongation in 2 in. (50 mm), min 35% For plates ≤ 3/4 in. (19 mm) thick. Slightly lower for thicker plates.
Hardness, max 90 HRB (Rockwell B) Typical Brinell Hardness (HBW) is ~180.
Important Fabrication Note: To achieve these mechanical properties and optimal corrosion resistance, the material and any welded fabrications must be supplied in the solution-annealed condition. This involves heating to a suitable temperature (e.g., 1100-1150°C) and rapidly quenching.

Application:

1. Water & Wastewater Treatment • Seawater Intake & Discharge Lines


2. Chemical & Petrochemical Processing


3. Offshore, Marine & Desalination • Desalination Plant high-pressure RO trains, inter-stage piping, and effluent lines.


4. Pulp & Paper Industry


5. Power Generation
