Monel K500 Seamless Pipes UNS N05500 W.Nr.2.4375 ASTM B163 B163 Monel Alloy K5-500

Monel K500 is a nickel-copper alloy with excellent corrosion resistance and high strength, widely used in marine engineering, chemical processing, and aerospace industries.

Material Description

• Alloy Name: Monel K500
• Chemical Composition: Mainly composed of nickel (63-70%) and copper (27-33%), also containing aluminum (2.3-3.15%), titanium (0.35-0.85%), and small amounts of iron, manganese, silicon, etc.
• Standards: ASME SB163, ASTM B163, ASTM B165, etc.

Characteristics

• High Strength: Monel K500 has significantly improved strength through the addition of aluminum and titanium elements and age-hardening treatment.
• Excellent Corrosion Resistance: Offers excellent resistance to corrosion in seawater and chemical environments, especially in chloride and sulfide environments.
• Resistance to Stress Corrosion Cracking: Exhibits good resistance to stress corrosion cracking in most freshwater and industrial environments.
• Low Magnetism: Maintains low magnetic properties even at low temperatures.

Physical Properties

• Density: 8.44 g/cm³
• Melting Point: 1350-1390 ℃
• Tensile Strength: 110 ksi (759 MPa)
