Monel Series

MONEL K-500

    STANDARD PRODUCT FORMS:


    Pipe, tube, sheet, strip, plate, round bar, flat bar, forging


    stock, hexagon and wire.

A precipitation-hardenable nickel-copper alloy that combines the corrosion resistance of MONEL alloy 400 with greater strength and hardness. It also has low permeability and is nonmagnetic to temperatures as low as -150°F (-101°C). Used for pump shafts, oil-well tools and instruments, doctor blades and scrapers, springs, valve trim, fasteners and marine propeller shafts.

2) Customization

Character

Resistant to seawater and steam at high temperatures.

Excellent resistance to rapidly flowing brackish water or seawater.

Excellent resistance to stress corrosion cracking in most freshwaters.

Particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated.

Offers some resistance to hydrochloric and sulfuric acids at modest temperatures and concentrations, but is seldom the material of choice for these acids.

Excellent resistance to neutral and alkaline salt.

Resistance to chloride induced stress corrosion cracking.

Good mechanical properties from sub-zero temperatures up to 1020° F.

High resistance to alkalis.
