Nickel K500
Alloy: K500 (UNS N05500)
Condition: Annealed, Aged (HT)
Form: Bar, Wire, Sheet, Plate, Forging
Size Range: Custom sizes available
BAOHUI STEEL supplies Nickel Alloy K500 (UNS N05500, commonly known as Monel K500), a precipitation-hardenable nickel-copper alloy that combines the excellent corrosion resistance of Monel 400 with significantly higher strength and hardness. Through the addition of aluminum and titanium, this alloy can be age-hardened to achieve superior mechanical properties while maintaining good corrosion resistance in various marine and chemical environments.
Key Features
High Strength
Yield strength up to 1100 MPa after aging
Excellent Corrosion Resistance
Comparable to Monel 400 in most environments
Age-Hardenable
Can be precipitation hardened for enhanced properties
Good Mechanical Properties
High strength maintained from cryogenic to elevated temperatures
Low Magnetic Permeability
Essentially non-magnetic in aged condition
Excellent Fatigue Strength
Superior performance under cyclic loading

Heat Treatment Process
Solution treatment (980-1010°C rapid cooling) → Age hardening (480-620°C holding).
Stress relief annealing (260-540°C) is suitable for welded parts.
Welding: TIG welding is recommended, using ERNiCu-7 wire, with controlled interlayer thickness.
