Monel 400 Supplier | Alloy 400 | UNS N04400 | Monel alloy 400 | En 2.4361

Siddhagiri Metals and Tubes are a well known  Supplier of Monel 400 with more than 3000 clients worldwide. Monel 400 is a product from a group of nickel alloys and is mainly made up of nickel and copper. It has around 67% nickel and the remaining copper. It also has other elements like iron, carbon, manganese and silicon. Alloy 400 has more strength than pure nickel and is mainly resistant to any kind of corrosion from many agents. It is also resistant to flowing seawater. It is a product that is easily fabricated with the help of processes like welding, machining, and cold working. It is, in fact, more expensive than stainless steel.

Alloy 400 Standards include UNS N04400 and Werkstoff.-nr. 2.4360 and En 2.4361.It is often named as Alloy 400 and Nickel-Copper Alloy 400.We manufacture and supply a variety of Monel Alloy 400 Products such as Alloy 400 Pipe ASTM B165 B725, Tube ASTM B163 B730, Flange ASTM B564, Pipe Fittings ASTM B366, Forged Fittings ASTM B564, Round Bar ASTM B164, Sheet and Plate ASTM B127, Fasteners, Swagelok and Parker A-Lok Equivalent Os-Lok® Tube Fittings. We keep these materials in stock and offer competitive prices as compared to others.

History of Monel

Monel Alloy 400 was discovered by David. H. Browne who was the chief metallurgist for International Nickel Co. It was named after the company president Ambrose Monell and it was finally patented in the year 1906. However, one L was not included in the name as usually family names were not permitted in trademarks in those days. Today the name is a trademark of Special Metals Corporation. It is an expensive product and has a cost that varies from five to ten times the actual cost of copper and  nickel . Thus, it is usually used only in those applications where no cheap alternatives can replace it. It is more expensive than piping in money and carbon steel.

Monel 400 Applications

Monel 400 is applied in industries like marine engineering, heat exchangers, chemical and hydrocarbon processings, heat exchangers, valves, and pumps. It is also used in alkylation units in the reacting section. Concentrated hydrofluoric acid is used while using Monel 400. It is also used in chemical processing, heat exchangers, hydrocarbon processing, pumps, and valves.

Special Chemical Composition of Monel 400

Alloy 400 can be used in any kind of environment and needs a lot of resistance to corrosion and heat and always retains its mechanical properties. It has 63% nickel, 28% to 34% Copper, and 2.5 % Iron along with around 2% Manganese. It has a metric-imperial property and a density of 8.8 g/cm3 along with 0.318lb/in3. It has a melting point of 1350°C, 2460°F and has a modulus of rigidity of 65.3 kN/mm2 and a modulus of elasticity of 105 – 120 kN/mm2.
