Monel 400 polished bar
Monel 400 polished bar is a high-performance metal bar made of nickel-copper alloy (Ni-Cu alloy, with a typical composition of 67% nickel, 30% copper, and small amounts of iron, manganese, etc.). It has a smooth and uniform mirror or matte surface after precision machining and surface polishing. Monel 400 polished bar has excellent corrosion resistance, high strength, and good machinability. It is an ideal material for harsh environments.
Monel 400 polished bar is widely used in marine engineering (ship parts, desalination), chemical industry (reactors, corrosion-resistant pipes), oil and gas (downhole tools, equipment in sulfur environments), aerospace (engine parts), and medical and food industries (sanitary parts). Its excellent corrosion resistance, high strength, and polished surface make it a key material in harsh environments.
Features of Monel 400 polished bar
Excellent Corrosion Resistance
Monel 400 polished bar performs well in seawater, acidic media (like sulfuric acid and hydrofluoric acid), alkaline solutions, and high-temperature steam. It has strong resistance to pitting and stress corrosion cracking. It is better than ordinary stainless steel.
High Strength and Toughness
Monel 400 polished bar keeps stable mechanical properties from low temperatures to high temperatures (-200°C to +600°C). Its tensile strength can reach 550-750 MPa. The elongation is over 35%.
Surface Treatment Advantages
The polished surface of Monel 400 polished bar reduces friction and improves anti-adhesion. It is suitable for applications that need cleanliness or good looks.
Easy Machinability
Monel 400 polished bar can be machined by turning, milling, welding and other common processes. No extra coating is needed after polishing.
Applications of Monel 400 polished bar
Marine Engineering: Monel 400 polished bar is used in ship pump shafts, valve components, and desalination equipment to resist seawater corrosion.
Chemical Equipment: Monel 400 polished bar is used to make reactors, heat exchanger pipes and pump and valve parts for transporting corrosive media.
Oil and Gas: Monel 400 polished bar is used to make downhole tools and flange fittings in oil and gas extraction. It can stand sulfur environments.
Aerospace: Monel 400 polished bar is used in engine fasteners and fuel system components. It can deal with both high stress and corrosion.
Medical and Food Industry: The polished surface of Monel 400 polished bar meets health standards. It is used in corrosion-resistant parts of medical implants or food processing equipment.
