Inconel 625 alloy square plate
Inconel 625 alloy square plate is a nickel-based superalloy square plate. It is made by cold rolling or hot rolling. It has standard square dimensions. The common thickness is from 5 mm to 50 mm. The side length can reach 2,000 mm. The main elements of Inconel 625 alloy square plate are nickel (≥58%), chromium (20-23%), and molybdenum (8-10%). It also contains niobium (3.15-4.15%) and elements like iron and titanium. These elements form a solid solution strengthened austenitic structure. The surface of Inconel 625 alloy square plate is usually polished, pickled, or sandblasted. This helps meet the corrosion-resistant needs in different industrial settings.
Inconel 625 alloy square plate is used in extreme environments. These include aerospace engine combustion chambers, marine engineering corrosion-resistant parts, nuclear reactor support components, and chemical equipment. It has excellent high-temperature strength, corrosion resistance, and weldability. These properties make it a key material for high-temperature, high-pressure, and corrosive media conditions. It greatly increases the life and safety of equipment.
Features of Inconel 625 alloy square plate
Extreme environment stability:High-temperature performance: Inconel 625 alloy square plate keeps its oxidation resistance at 980℃. It can handle short-term temperatures up to 1200℃.
Corrosion resistance: Inconel 625 alloy square plate strongly resists chloride stress corrosion cracking (SCC). In seawater and acidic oil and gas environments, its corrosion rate is less than 0.1 mm per year.
Excellent mechanical properties: At room temperature, its tensile strength is at least 830 MPa. Its elongation is at least 30%. It has both high strength and good formability. Inconel 625 alloy square plate can be welded (with ERNiCrMo-3 welding wire) to make complex structures.
Material consistency: Inconel 625 alloy square plate is made by vacuum induction melting (VIM) + electroslag remelting (ESR). This ensures that the plate's composition segregation is no more than 0.5%. It passes the ultrasonic testing according to ASTM B564.
Applications of Inconel 625 alloy square plate
Aerospace: Inelcon 625 alloy square plate is used for engine combustion chamber liners and rocket nozzle adjustment blades. It can handle high-temperature gas erosion.
Marine engineering: Inconel 625 alloy square plate is used as the sealing surface material for subsea pipeline flanges. It resists corrosion from H₂S/CO₂ acidic media.
Energy equipment: Inconel 625 alloy square plate is used for nuclear reactor control rod drive mechanism supports and LNG heat exchanger plates. It keeps its performance under irradiation and extremely low temperatures.
Chemical processing: Inconel 625 alloy square plate is used to make square containers for concentrated sulfuric acid evaporators. It replaces the traditional Hastelloy C276 and cuts costs by 15%-20%.
