Applications of ASTM B443 N06625 Nickel Alloy Plate

ASTM B443 N06625, widely known as Inconel 625, is a nickel-based alloy plate prized for its exceptional corrosion resistance, high-temperature strength, and versatility. Composed of nickel (≥58%), chromium (20–23%), molybdenum (8–10%), and niobium (3.15–4.15%), it is extensively used across industries requiring durability in harsh environments.

Aerospace: Inconel 625 plates are critical in aerospace applications, such as turbine shroud rings, thrust reversers, and jet engine exhaust systems. The alloy’s ability to withstand temperatures up to 1093°C (2000°F) and resist oxidation ensures reliability in high-stress components.

Marine Engineering: Its superior resistance to chloride-ion stress corrosion cracking and pitting makes it ideal for seawater processing equipment, pipelines, and fasteners. The alloy is widely used in offshore platforms and marine vessels exposed to corrosive saltwater environments.

Chemical Processing: Inconel 625 excels in chemical plants handling acidic media like sulfuric, hydrochloric, and phosphoric acids. It is used in reactors, heat exchangers, and storage tanks, where its corrosion resistance ensures long-term performance.

Energy and Oil & Gas: Compliant with NACE MR0175/ISO 15156, Inconel 625 plates are employed in oil and gas pipelines, wellhead components, and flare stacks, withstanding sour gas and high-pressure conditions.

Available in annealed (Grade 1) or solution-annealed (Grade 2) conditions per ASTM B443, these plates are supplied in various thicknesses (0.3–75 mm) and sizes (e.g., 1000 x 2000 mm). Certified to international standards, Inconel 625’s robust properties make it indispensable for critical applications in extreme environments.
