ASTM B444 UNS N06625 inconel 625 pipe Product Description:

Inconel Alloy 625 (UNS N06625.W.Nr. 2.4856) is an austenitic nickel-based superalloy known for its high strength at elevated temperatures, excellent machinability, and excellent oxidation resistance under a wide range of corrosive conditions and corrosion resistance.

ASTM B444 UNS N06625 Inconel 625 has high strength and toughness in the low temperature range to 2000°F (1093°C) due to the solid solution effect of refractory metals, niobium and molybdenum in a nickel-chromium matrix. Nickel alloy Inconel 625 has excellent fatigue strength and stress corrosion cracking resistance to chloride ions. Additionally, the corrosion resistance of Inconel 625, especially over a wide temperature and pressure range, makes Inconel Alloy 625 Tubing ideal for the chemical processing industry for thin-wall vessels or tubing, heat exchangers, transfer piping, and valves.

ASTM B444 UNS N06625 Steel Pipes are furnished in two grades of different heat-treated conditions:

Grade 1 (annealed)—Material is normally employed in service temperatures up to 1100°F (593°C).

Grade 2 (solution annealed)—Material is normally employed in service temperatures above 1100°F (593°C) when resistance to creep and rupture is required.

ASTM B444 UNS N06625 Steel Pipes Properties

Note: 

Annealed at 1600°F (871°C) minimum. 

Solution annealed at 2000°F (1093°C) minimum, with or without subsequent stabilization anneal at 1800°F (982°C) minimum to increase resistance to sensitization.
