NS338 Alloy Nickel Based Alloys High Strength Nickel Chromium Molybdenum Alloy

NS338 Alloy is a high-strength, corrosion-resistant nickel-chromium-molybdenum alloy. This high-performance material is known for its superior strength, corrosion resistance, and high-temperature stability, making it ideal for harsh environments where durability and resistance to aggressive conditions are crucial.

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

• Tensile Strength: Approximately 800-950 MPa - Offers high strength for components that endure significant mechanical stress.
• Yield Strength: ≥500 MPa - Provides reliable resistance to deformation under stress.
• Elongation: ≥30% - High ductility allows 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 - Ensures wear resistance and durability.

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