With over 250 customers in India and overseas, Metalica is one of the largest suppliers and stockists of Monel 400 or Alloy 400. The nickel alloys we purchase and export come from factories in India and overseas (USA, Japan, Korea, and Europe), and we are able to offer the best price and quality to you.

We stock all major forms of Alloy 400 grade such as pipe and tube, Monel 400 flanges and fittings, Monel 400 butt-welding pipe fittings, Alloy 400 elbow, Alloy 400 tee, Monel Alloy 400 reducer, Alloy 400 stub end, gaskets, fasteners, valves, etc. Our large volume of Monel 400 suppliers allows us to guarantee you the best prices.

Metallica Metals sells in volume and has a global customer base, allowing us to work on low margins. We have an extensive trader network across India and the Middle East, who regularly buy from us.

In addition to traders, we have a number of EPC contractors, companies, and end users in various industries as our customers for nickel and nickel alloy steel. In addition to marine engineering and chemical and hydrocarbon processing equipment, Monel 400 is also used in valves, pumps, shafts, flanges, fittings, fasteners, and heat exchangers.

Monel 400 (UNS N04400 or DIN W.Nr. 2.4360 / 2.4361) is a solid-solution nickel-copper alloy with excellent resistance to a wide range of media, including seawater, hydrofluoric acid, sulfuric acid, and alkalies. In most fresh and industrial waters, Alloy 400 also resists stress-corrosion cracking and pitting corrosion.

What are the Properties of Monel 400 or Alloy 400?

• Monel 400 is widely used in the marine industry, as well as heat exchangers. However, its low-annealed strength often requires strengthening. Tempering is often required to improve hardness and elasticity.
• Monel 400 can be readily joined by welding processes including shielded metal arc welding(SMAW), gas tungsten arc welding(GTAW), and gas metal arc welding(GMAW). Corresponding fillers or electrodes shall be selected. Generally, Monel 400 products should be annealed at a temperature of 1470°F (full annealing) and pickling is often required to produce bright and clean surfaces on the alloy.
• There are many critical industries that can benefit from Monel products. It can be welded, soldered, and brazed easily due to:
• Like many nickel alloys, it is highly corrosion-resistant to acids and alkalis. Due to its resistance to substances such as seawater and other caustic solutions, this metal is used in acidic and alkaline environments. Monel 400 has a low oxidation resistance as well; however, it has excellent corrosion and stress resistance in salt water, fresh water, brackish water, and hydrochloric environments. Due to its reduced cost and better ability to withstand pressures and temperatures, Monel 400 offers the same corrosion resistance as nickel.
• Very high mechanical strength
• Good ductility
• Relatively low cost
• Due to its softness, Alloy 400 can be hot-formed or cold-formed into almost any shape following the machining process, including sheets, plates, rods, bars, and tubes.
