NS336 Alloy Nickel Based Alloys Corrosion Resistant Nickel Chromium Molybdenum Alloy

NS336 Alloy Is A High-Strength, Corrosion-Resistant Nickel-Chromium-Molybdenum Alloy.

NS336 Alloy is a high-performance, corrosion-resistant nickel-chromium-molybdenum alloy known for its exceptional strength, toughness, and resistance to a variety of harsh environments. It is particularly used in applications where both high strength and resistance to aggressive conditions are required.

Chemical Composition:

NS336 Alloy is characterized by its specific blend of alloying elements:

• Nickel (Ni): 60.0-65.0% – Provides excellent corrosion resistance, particularly in acidic and chloride environments, and contributes to the alloy's overall toughness.
• Chromium (Cr): 15.0-20.0% – Enhances resistance to oxidation and improves the alloy’s resistance to corrosion and high-temperature environments.
• Molybdenum (Mo): 3.0-5.0% – Increases resistance to pitting and crevice corrosion, and improves high-temperature strength.
• Iron (Fe): Balance – Provides the base for the alloy and contributes to its mechanical properties.
• Other Elements: Trace amounts of elements such as manganese, silicon, and carbon, which help in controlling the alloy's overall properties and performance.

Mechanical Properties:

NS336 Alloy is known for its robust mechanical properties, which make it suitable for demanding applications:

• Tensile Strength: Approximately 800-950 MPa – Offers high strength, making it suitable for components under significant mechanical stress.
• Yield Strength: ≥500 MPa – Ensures that the material can withstand considerable stress without permanent deformation.
• Elongation: ≥30% – Demonstrates high ductility, allowing for effective forming and shaping without cracking.
• Density: Approximately 8.0 g/cm³ – Provides a good balance between strength and weight.
• Hardness: Typically Rockwell C 30-40 – Offers a suitable level of hardness for resistance to wear and deformation.

Corrosion Resistance:

NS336 Alloy excels in resisting various forms of corrosion:

• Oxidation Resistance: Excellent, even at elevated temperatures, due to the high chromium content.
• Pitting and Crevice Corrosion: Outstanding resistance due to the presence of molybdenum.
• Acidic Environments: High resistance to acids, including sulfuric and phosphoric acids.

Applications:

NS336 Alloy is used in a variety of industries where high performance and corrosion resistance are critical:

• Chemical Processing: Used for equipment such as reactors, heat exchangers, and pumps that handle aggressive chemicals.
• Aerospace: Employed in components that require high strength and resistance to high temperatures and corrosion.
• Marine Industry: Suitable for marine environments due to its excellent resistance to seawater corrosion.
• Oil and Gas: Utilized in downhole equipment, valves, and piping that face harsh conditions and require high durability.
• Power Generation: Used in parts exposed to high temperatures and corrosive environments, such as turbine blades and generators.

Heat Treatment:

NS336 Alloy can be heat treated to further enhance its mechanical properties:

• Annealing: Softens the alloy to improve machinability and relieve stresses.
• Solution Treating: Enhances corrosion resistance and mechanical properties by optimizing the alloy’s microstructure.

Summary:

NS336 Alloy is a high-performance nickel-chromium-molybdenum alloy known for its exceptional strength, toughness, and resistance to corrosion and high-temperature environments. Its robust chemical composition and versatile applications make it ideal for use in chemical processing, aerospace, marine, oil and gas, and power generation industries. The alloy’s ability to withstand harsh conditions while maintaining high mechanical properties ensures its reliability in demanding applications.
