Common Trade Names: Monel R405; Alloy R405; Nickel 405; Monel 405; Alloy 405. Monel nickel-copper alloy R-405 (UNS N04405) is the free-machining grade of alloy 400. Its greater sulfur content enhances machinability. It has essentially the same corrosion resistance and physical properties as alloy 400, but a slightly different range of mechanical properties. Alloy R-405 is used chiefly for automatic screw machine stock and is not generally recommended for other applications Available Product Forms:  Round bar, sheet, plate, pipe,hexagon and wire ect Technical Data Sheet Chemical Composition Limits Weight % Ni+Co C Mn Fe S Si Cu Monel 405 63 min 0.3 max 2.0 max 2.5 max 0.025 - 0.060 0.5 max 28.0-34.0 Typical Mechanical Properties Material Form and Condition Tensile Strength Ksi Yield Strength (0.2% Offset) Ksi Elongation (%) Hardness Rockwell B Alloy 405 Rod and Bar Annealed 70-85 25-40 50-35 60-76 Alloy 405 Rod and Bar Cold- Drawn, As- Drawn 85-115 50-105 35-15 85-23C Alloy 405 Rod and Bar Hot Finished 75-90 35-60 45-30 72-86 Availability Alloy 405 (UNS N04405) is available in Rod and Bar (Round).
