Marine Engineering Field Nickel Alloy Inconel 625 Strip 13.3 W/(M·K) Corrosion Resistance

Marine Engineering Field Nickel Alloy Inconel 625 Strip 13.3 W/(M·K) Seawater Corrosion Resistance

Product Introduction

Inconel 625 strip is a high-performance nickel-chromium-molybdenum-niobium-based alloy strip with excellent corrosion resistance and high strength, and is widely used in the field of marine engineering. Its main components include nickel (about 58%), chromium (20-23%), molybdenum (8-10%) and niobium (3.15-4.15%), which give it excellent resistance to pitting, crevice corrosion and chloride ion stress corrosion cracking. The application of Inconel 625 strip in marine engineering includes heat exchangers and piping systems for desalination equipment, supporting structures for offshore platforms, propulsion systems for ships and submarines, turbine blades for marine energy development equipment, and submarine cables. It has a density of 8.4 g/cm³, a melting point between 1290-1350°C, and is able to maintain good mechanical properties in the wall temperature range of -196°C to 450°C. In addition, Inconel 625 strip also has good processability and weldability, no post-weld cracking sensitivity, and meets the highest standard of Class VII for sour gas environment use in accordance with NACE certification (MR-01-75). These characteristics make it an ideal choice for marine engineering, ensuring long-term and stable operation of equipment in harsh marine environments.

Specific Applications

1. Desalination equipment:Inconel 625 Strip is used in heat exchangers and piping systems in desalination plants and is well suited for treating seawater due to its excellent resistance to chloride ion corrosion.
2. Offshore platforms and structures:The support structures, jackets and subsea facilities of offshore platforms are often subject to seawater corrosion. Inconel 625 Strip is used in the manufacture of these structures to provide long-term corrosion protection.
3. Ships and submarines:The propulsion systems, propellers, shafts and sealing systems of ships, as well as the pressure hulls and piping systems of submarines, may benefit from the high strength and corrosion resistance of Inconel 625 Strip.
4. Marine energy development:In offshore wind power and tidal power generation equipment, Inconel 625 Strip can be used to manufacture components exposed to seawater, such as turbine blades and submarine cables.
5. Marine research equipment:Marine research vessels and submersibles may be manufactured using Inconel 625 Strip to resist pressure and corrosion in deep-sea environments.
6. Offshore oil and gas exploration:In offshore oil and gas exploration and production, Inconel 625 Strip can be used to manufacture subsea pipes, valves, pumps and wellhead equipment, which are often exposed to corrosive environments.
7. Marine anti-corrosion coating:Inconel 625 Strip is sometimes also used as an anti-corrosion coating for other metal structures to provide an additional layer of corrosion protection.

Advantages and Characteristics

• Good Mechanical Properties:Inconel 625 Strip exhibits good strength and toughness at room and elevated temperatures. Its yield strength and tensile strength are both relatively high, making it an excellent performer when subjected to mechanical stress. In addition, the alloy maintains relatively high ductility at elevated temperatures, reducing the risk of brittle fracture.
• Low Coefficient of Thermal Expansion:Inconel 625 Strip has a relatively low coefficient of thermal expansion, meaning that its dimensions change less when the temperature changes. This property enables it to maintain a stable shape in high-temperature applications, reducing structural damage caused by thermal expansion.
• Good Processing:Inconel 625 Strip has good welding and forming properties and can be processed by a variety of methods, such as cold working and hot working. This property makes the material very convenient when manufacturing parts with complex shapes.
• Excellent Fatigue Properties:Inconel 625 Strip maintains good fatigue properties even when subjected to repeated loading. This makes it perform well in demanding mechanical cycles and vibration environments, especially in the aerospace and engine fields.

Summary

Due to its excellent corrosion resistance, high temperature stability and good mechanical properties, Inconel 625 Strip is widely used in seawater desalination equipment, offshore platforms and structures, ships and submarines, marine energy development, marine research equipment, marine oil and gas exploration, marine anti-corrosion coatings, marine anchor chains and mooring systems, marine sensors and monitoring equipment, and marine engineering accessories in the field of marine engineering, ensuring the long-term stable operation of equipment in high temperature, high pressure and corrosive environments.
