Monel 400 Pipes, manufactured and supplied by Rose Metal Industries, are high-performance nickel-copper alloy pipes widely used in industries requiring exceptional corrosion resistance. With a nominal nickel content of approximately 63% and copper around 28–34%, Monel 400 offers excellent strength and durability in aggressive environments such as seawater, acidic conditions, and chemical processing plants. Rose Metal Industries is a leading manufacturer, stockist, and exporter of Monel 400 Pipes across Tamil Nadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry), and the Andaman & Nicobar Islands..
Monel 400 Pipes are composed primarily of nickel (63%) and copper (28–34%), with small amounts of iron, manganese, and carbon. This balanced composition provides outstanding corrosion resistance in seawater and industrial chemicals while maintaining high tensile strength and toughness. Typical mechanical properties include a tensile strength of 550–690 MPa, yield strength of 240–380 MPa, and elongation above 30%, making them suitable for demanding engineering applications.
Monel 400 Pipes are internationally recognized under ASTM B165, ASME SB165, and UNS N04400. These equivalent standards ensure that the pipes meet global quality requirements and can be used interchangeably with other certified materials in chemical, petrochemical, marine, and offshore industries.
