What is the ASME specification for Monel 400?
Monel 400 pipe conforms to ASTM B165 and ASME SB165 international standards. Its wide variety of shapes, wall thicknesses, and sizes helps meet the specific needs of various industries, ensuring consistent quality and reliability.
Monel 400 tubing is a nickel-copper alloy known for its exceptional corrosion resistance and mechanical strength, especially in harsh environments. Alloy 400 tubing is a solid solution alloy that can only be hardened by cold working. This nickel alloy offers excellent corrosion resistance, weldability, and high strength. Its low corrosion rate in fast-moving brackish or seawater, excellent resistance to stress corrosion cracking in most freshwaters, and resistance to a wide range of corrosive conditions make it widely used in marine applications and other non-oxidizing chloride solutions.

Manufacturing and Processing
Specification: ASME SB163 covers cold-worked seamless nickel and nickel alloy tubing.
Sizes: Available in a wide range of sizes, such as ½-inch to 12-inch outside diameter, with wall thicknesses from 0.8 mm to 12.7 mm, and lengths up to 26 meters.
Forming: Forming, bending (U-bends), and machining are possible, but require strict setups and specific processes to avoid work hardening.
Hardness: Available in the cold-hardened or annealed condition.
Testing and Certification
Required Testing: To ensure compliance with specifications, tubing undergoes chemical analysis, tensile testing, hydrostatic testing, and non-destructive electrical testing.
Other Testing: Other testing may include hardness, grain size, flaring, and flattening.
Certification: Material certificates, such as EN 10204 Type 3.1, are available to confirm that all specified testing has been completed.
