Monel Fittings & Flanges

Monel fittings and flanges (Alloy 400 and K500) are nickel-copper alloys with outstanding resistance to seawater, brackish water, hydrofluoric acid, and reducing media. Monel K500 adds precipitation hardening for higher strength. These alloys are the standard choice for marine and naval applications. Shree Raj Steels supplies Monel fittings to ASTM B366 and flanges to ASTM B564.
