Monel is a high-performance nickel-copper alloy series known for its exceptional strength and corrosion resistance in a wide range of media. From high-velocity seawater to volatile hydrofluoric acid, Monel remains the industry standard for marine engineering and chemical processing.
Monel alloys exhibit a low corrosion rate in flowing seawater and excellent resistance to stress-corrosion cracking in most freshwaters. While Monel 400 is the versatile workhorse, Monel K500 is age-hardened to provide significantly higher strength and hardness for heavy-duty shafts.
| Grade | Ni (Nickel) | Cu (Copper) | Fe (Iron) | Mn (Manganese) | Si (Silicon) | Al (Aluminum) | Ti (Titanium) |
|---|---|---|---|---|---|---|---|
| Monel 400 | 63.0 min | 28.0 - 34.0 | 2.5 max | 2.0 max | 0.5 max | - | - |
| Monel K500 | 63.0 min | 27.0 - 33.0 | 2.0 max | 1.5 max | 0.5 max | 2.3 - 3.15 | 0.35 - 0.85 |
| Grade | Tensile Strength (PSI) | Yield Strength (PSI) | Elongation (%) | Hardness (Rockwell) | Magnetic Permeability |
|---|---|---|---|---|---|
| Monel 400 | 80,000 min | 35,000 min | 40% min | 65 - 80 HRB | Ferromagnetic |
| Monel K500 | 140,000 min | 100,000 min | 20% min | 25 - 35 HRC | Non-Magnetic |
Marine Grade
High-strength nickel-copper sections providing excellent resistance to rapidly flowing seawater and brackish water. Essential for heat exchangers in refineries and offshore splash zone piping.
Forged / Buttweld / SW
A comprehensive range of fittings including Buttweld (seamless/welded) and Forged high-pressure components designed to handle hydrofluoric acid and sulfuric acid environments.
Seawater Resistant
Durable flat-rolled products used for fabricating marine hardware, chemical tanks, and fuel heaters. Offers excellent toughness even at sub-zero temperatures.
Forged Marine Sealing
Precision forged flanges designed for leak-proof connections in subsea piping, marine propulsion systems, and alkylation units in oil refineries.
High-Strength Bolting
Heavy-duty bolting solutions including stud bolts and nuts. Monel K500 fasteners offer high-tensile strength and are non-magnetic for specialized subsea tools.
Propeller Shaft Quality
High-strength round bars and age-hardened K500 shafts. Specifically engineered for marine propeller shafts, pump impellers, and valve stems.
