N08020 — ASTM Equivalent
Holding a datasheet that specifies N08020 (UNS)? The valve-grade equivalent, its properties, and certified supply of the matching ASTM grade.
What is the ASTM equivalent of N08020?
N08020 is a UNS designation corresponding to ASTM A351 CN7M / ASTM A182 (Alloy 20 / Carpenter 20) (Alloy 20 (Carpenter 20Cb-3)) and A351 CN7M (Alloy 20 Cast (CN7M)) 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.
A351 CN7M / ASTM A182 (Alloy 20 / Carpenter 20)
Nickel AlloysAlloy 20 (Carpenter 20Cb-3) - both form.
Typical service: Sulphuric acid (H₂SO₄) at all concentrations: dilute, concentrated, oleum; Phosphoric acid manufacturing; Fertilizer and ammonium sulphate plants
A351 CN7M
Stainless SteelAlloy 20 Cast (CN7M) - cast form.
Typical service: Sulphuric acid at concentrations 5–98% and temperatures up to 80°C; Phosphoric acid and mixed acid (H₂SO₄ + H₃PO₄) service; Sodium bisulphate and acidic salt solutions
