Inconel 625 (UNS N06625) is a nickel-chromium-molybdenum alloy renowned for its extraordinary strength and superior resistance to corrosion. Inconel 625 flanges are engineered to withstand the most demanding industrial applications, from deep-sea oil extraction to aerospace exhaust systems.
Inconel 625 is a "workhorse" in the specialty metal industry. Unlike standard stainless steel, it maintains its integrity in environments where others fail.
Exceptional Corrosion Resistance: Highly resistant to pitting, crevice corrosion, and intergranular attack. It is virtually immune to chloride-induced stress corrosion cracking.
High Temperature Stability: Operates effectively from cryogenic temperatures up to 982°C (1800°F).
Superior Mechanical Strength: The combination of nickel and chromium, fortified with molybdenum and niobium, provides high fatigue strength and toughness without the need for age-hardening heat treatments.
Oxidation Resistance: Excellent resistance to oxidation and scaling at elevated temperatures.
Our Inconel 625 flanges are essential components in industries where safety and durability are non-negotiable:
Marine & Offshore: Ideal for seawater piping, propeller blades, and submarine auxiliary motors due to its resistance to salt-water corrosion.
Chemical Processing: Used in equipment handling highly acidic media, such as phosphoric acid or sulfuric acid environments.
Oil & Gas: Crucial for sour gas (H2S) production and high-pressure wellhead components.
Aerospace: High-temperature ducting systems and engine exhaust components.
Nuclear Power: Core components and fuel element spacers.
