About Monel R-405
Free-machining Monel R-405 in bar and rod for valve and pump components in marine and chemical service.
Monel R-405 (UNS N04405) is the free-machining version of Monel 400, with a controlled sulphur addition of 0.025–0.060% that breaks chips on automatic screw machines. Corrosion behaviour in seawater, hydrofluoric acid and alkaline media matches Monel 400, so it is specified where high-volume machined fasteners, valve stems and instrument parts are required.
Steelco Metal & Alloys stocks Monel R-405 (UNS N04405) in Mumbai, India as a stockist, importer and exporter, and ships to 40+ countries. Every dispatch carries EN 10204 3.1 (3.2 on request) mill test certificates, PMI verification and is open to third-party inspection.
