wrought — ASTM Equivalent

Holding a datasheet that specifies wrought (UNS)? The valve-grade equivalent, its properties, and certified supply of the matching ASTM grade.

What is the ASTM equivalent of wrought?

wrought is a UNS designation corresponding to ASTM A890 Grade 5A (Super Duplex 2507 (Grade 5A Cast)) for industrial valve service. The full grade data is below - equivalence is by nominal chemistry and mechanical class, so confirm composition and heat-treat condition against the governing standard before substituting in critical service.

A890 Grade 5A

Duplex & Super Duplex

Super Duplex 2507 (Grade 5A Cast) - cast form.

Service temperature-46°C to +300°C
Nominal compositionC ≤ 0.03%, Mn ≤ 1.20%, Si ≤ 0.80%, Cr 24.00–26.00%, Ni 6.00–8.00%, Mo 3.00–5.00%, N 0.24–0.32%, Cu ≤ 0.50%

Typical service: Deepwater subsea valves - seawater injection and well-testing at high chloride, high pressure; Offshore produced water re-injection (PWRI) valves - H₂S + CO₂ + chloride environments; FGD (flue gas desulphurisation) slurry recirculation valves - high-Cl sulfate solution
