Monel flanges

monel flanges

Monel 400 or Monel material is alloy of nickel and copper, which is quite popular and known for its high performance. The Monel 400 Flanges are mostly found in the high performance and critical applications. The Alloy 400 Slip on Flanges is known for its high strength, and it shows excellent resistance to acidic and alkaline applications. The Monel 400 Pipe Flanges material has high ductility and thermal conductivity. The Monel Flanges can be used in services within the temperature range of subzero to 538 degrees C. The Wnr 2.4360 Reducing Flanges material can be hardened only by the cold working procedure. Due to all these properties, the Class 150 Monel 400 Rtj Flanges can be found applications like chemical and hydrocarbon process equipment, marine engineering, and so on.
