Monel K500 Pipe Industrial Applications

Alloy K-500 pipe serves industries that demand high strength and corrosion resistance.

Oil & Gas Industry

Monel K500 pipe serves demanding oilfield applications such as deep well pump shafts, production tubing strings, and harsh sour gas completions.

Marine Engineering

Alloy K-500 pipe is essential for marine propeller drive shafts, seawater transport systems, and structural components on offshore platforms worldwide.

Chemical Processing

Monel K500 pipe safely conveys hydrofluoric acid, various alkaline brine solutions, and low-oxygen sulphuric acid in demanding chemical processing services.

Monel K500 vs Monel 400 Pipe

Monel K500 pipe and Monel 400 pipe have the same corrosion resistance, but K500 provides higher strength through age hardening. K500 is the better choice when corrosion resistance and high load capacity are both required.

Property Monel K500 Monel 400
Tensile Strength (min) 690 MPa (100 ksi) 480 MPa (70 ksi)
Yield Strength (min) 483 MPa (70 ksi) 170 MPa (25 ksi)
Hardening Age-hardenable (Ni3Al, Ni3Ti) Non-hardenable
Key Addition Al 2.30 to 3.15%, Ti 0.35 to 0.85% None (Ni-Cu binary)
