What is the density of MONEL 400?

8800 kg/m³ — the figure the weight calculators on this site use for MONEL 400. The value is Special Metals / nickel alloy datasheets’s.

What is the chemical composition of MONEL 400?

C ≤ 0.3, Si ≤ 0.5, Mn ≤ 2, S ≤ 0.024, Ni ≥ 63, Cu 28–34, in mass %, to ASTM / Special Metals. An element the standard sets no requirement for is left blank here rather than written as zero.

What are the mechanical properties of MONEL 400?

Tensile ≥ 485 MPa, Yield ≥ 195 MPa, Elongation min ≥ 35 % — ASTM B127/vendor reference, Plate/Sheet, Annealed. Those are the standard’s requirements; the mill test certificate governs the metal delivered.
