What Is Monel 400 Spiral Wound Gasket?

Monel 400 is an alloy (nickel 67% and copper 30%) known for its resistance to seawater at high temperatures. Hence it is only natural that a monel 400 spiral wound gasket is employed in such services. Not only that, but the alloy is also corrosion-resistant to neutral and alkaline salts and aerated hydrochloric and hydrofluoric acids. These have a hardness of around 125-215 HB and per the ASME standards, are coded in Orange. The alloy has characteristic high strength and weldability, which are also seen in the gaskets manufactured from it.
