Nickel Alloy monel 400 tube has excellent resistance to corrosion by many reducing media such as sulfuric and hydrochloric acids. It is generally more resistant to corrosion by oxidizing media than higher copper alloys. Nickel Alloy 400 resists pitting and stress corrosion cracking in most fresh and industrial waters. It has good resistance in flowing seawater, but under stagnant conditions, pitting and crevice corrosion are induced. Nickel Alloy 400 is probably the most resistant to hydrofluoric-acid in all concentrations up to the boiling point, of all engineering alloys. Nickel Alloy 400 is notable for its toughness, it does not show embrittlement tendency at cryogenic temperatures. It works hardenable.

• Chemical Properties of Monel 400 tube

• Application

Alloy 400 has been widely used in a variety of industries, and has been particularly useful in the marine industry and chemical processing industry. Typical applications include pumps and valves, propeller shafts, marine fixtures and fasteners, electronic components, springs, chemical processing equipment, fresh and salt water tanks, process vessels and piping, boiler feedwater heaters and other heat exchangers.
