What This Product Is For
Monel Alloy K500 is a nickel copper superalloy with high strength and strong corrosion resistance in marine environments. It is held in stock as coils, sheets, strips, plates, round bars, pipe fittings, flanges, fasteners, valves, angles and channels, so a complete assembly can be sourced in one grade. Stock deliveries run about 7 to 10 days.
Key Benefits
- Higher mechanical strength than standard nickel copper alloy while keeping the same corrosion behaviour
- Holds its properties at elevated temperature, which suits pump shafts and valve internals
- Good resistance to stress corrosion cracking in seawater service
- Fabricates and welds without special equipment
- Stock coverage across bar, plate, fittings and fasteners means one grade for the whole assembly
Who It Is For
- Pump and valve manufacturers building seawater rated equipment
- Marine and offshore fabricators
- Maintenance teams replacing corroded shafting and fasteners
- Distributors stocking nickel copper alloy product forms
Problems It Solves
- Stainless shafting that pits and seizes in seawater
- Stress corrosion cracking on loaded components in brine
- Long waits for a nickel copper grade that has to be rolled to order
- Mixed grade assemblies where fasteners fail before the body does
Application Scenarios
- Pump shafts and impeller hardware in seawater service
- Valve stems and trim exposed to brine and chlorides
- Marine equipment and offshore fittings
- High strength fasteners that have to resist corrosion at temperature

| Typical Applications | Fasteners, pump shafts, valves, marine equipment |
Technical Features
- Nickel copper superalloy in the K500 grade
- High mechanical properties retained at elevated temperature
- Excellent resistance to stress corrosion cracking
- Readily fabricated and welded
- Stocked as coils, sheets, strips, plates, round bars, pipe fittings, flanges, fasteners, valves, angles and channels
Materials
- Nickel copper alloy K500
Manufacturing Process
- Forging
- Hot and cold rolling
- Machining
- Welding
Quality Control
- Grade confirmed against the K500 nickel copper composition before release
- Product form and dimensions checked against the order
- Stock traced to heat so a certificate can follow the item
- Surface inspected for forging and rolling defects
Customisation Options
- Any of the stocked product forms cut or machined to your drawing
- Matching fasteners and flanges supplied with the main component
- Bar sizes cut to length from stock
Use Guide
- Specify the product form and finished dimensions, since stock covers bar through to valves
- Machine with sharp tooling and positive feed to avoid work hardening the surface
- Match fasteners to the body grade so the assembly corrodes evenly
- Confirm the delivery window on order, as stock items ship in about 7 to 10 days
How It Compares With the Alternatives
| Monel 400 | K500 is the higher strength member of the same nickel copper family, so it is chosen where a shaft or fastener is loaded rather than simply wetted |
|---|---|
| 316 stainless steel | K500 resists seawater pitting and stress corrosion cracking far better than 316 in flowing and stagnant brine |
| Duplex 2205 | Duplex is cheaper and strong, but K500 is preferred where copper bearing corrosion behaviour and biofouling resistance matter |
