Monel® K-500
Monel K-500 is a precipitation-hardenable nickel-copper alloy. It combines the excellent corrosion resistance characteristic of Monel 400 with the added advantages of greater strength and hardness, achieved through the addition of aluminum and titanium and a controlled heat treatment cycle.
- الأشكال الشائعة: Round Bar, Shafting, Rod, Forgings, Wire.
- الميزة الرئيسية: High strength (approx. 3x the yield strength of Monel 400).
- Special Property: Non-magnetic, even at temperatures as low as -200°F.
- Condition: Typically supplied in the age-hardened condition.
Select Monel K-500 when you need the corrosion resistance of the standard nickel-copper alloy but require significantly higher mechanical properties. Its unique combination of high strength, corrosion resistance, and non-magnetic properties makes it ideal for demanding applications.
High Strength & Hardness
Through age-hardening, K-500 achieves yield strengths up to 110 ksi (compared to ~30 ksi for annealed Monel 400), making it suitable for heavy-duty shafts.
مقاومة التآكل
Maintains virtually the same outstanding resistance as Monel 400 to sea water, sour gas environments, and various chemical process streams.
غير مغناطيسية
Remains non-magnetic down to cryogenic temperatures, a critical property for electronic housing and specialized oilfield survey instruments.
