Monel 400 vs Monel K500 Key Difference
K500 is Monel 400 with aluminium and titanium added, then age-hardened.
Adds Al and Ti
2.30 – 3.15% Al, 0.35 – 0.85% Ti
About 3× the Yield
And about double the tensile strength
Age-Hardened
Monel 400 hardens by cold work only
Stays Non-Magnetic
Monel 400 can turn magnetic near room temperature
- Order Monel 400 for pipe, tube and welded lines (ASTM B165).
- Order K500 for pump shafts, impellers and fasteners (ASTM B865).
- Seawater corrosion resistance is about the same in both.
- Age-hardened K500 is more prone to stress-corrosion cracking.

Weight Check
1 in. Sch 40 = 2.81 kg/m
Stencil
ASTM B165, N04400, heat number
Certificate
EN 10204 3.1, same heat number
- Curie point is 21 – 49°C, so some genuine heats attract a magnet.
- Density is 8.80 g/cm³, heavier than stainless steel.
- Reject pipe whose stencil and certificate heat numbers differ.
