Amardeep Steel offers Alloy 400 (UNS N04400), a ductile nickel-copper alloy renowned for its
resistance to various corrosive conditions. It is commonly used in mildly oxidizing to neutral
environments and moderately reducing conditions. The material also finds application in nonoxidizing
chloride solutions and marine environments.
The UNS N04400 Strip is a narrow form of the plate used for lining applications, filling gaps in
larger plate structures, and producing pipes and tubes of the same grade. With a higher density than
304-grade steel (8.8 g/cm³), it provides excellent performance. As a leading Monel 400 coil
supplier, Amardeep Steel manufactures and supplies coils for high-temperature applications.
The material has a high melting point of 1350 degrees Celsius, along with a minimum yield strength of
240 MPa and a minimum tensile strength of 550 MPa. Contact us for more information on ASTM B 127 400
Monel Shim Sheets, Plates, Strips, and Coils, as well as pricing details.
Monel 400 Plate is a copper-nickel alloy known for its ductility and corrosion resistance against
various corrosive media. It exhibits high operating temperatures, ranging from cryogenic temperatures up
to 1000 °F. The plate demonstrates good pitting and corrosion resistance, with mechanical properties
varying based on cold- or hot-rolling procedures. Conforming to ASTM B127 specifications, the dimensions
of Monel 400 plates can vary. Trust Amardeep Steel for reliable Monel 400 plates and other products.
