PRODUCT DESCRIPTION

Monel K-500 (UNS N05500/ W.Nr 2.4375) is a precipitation-strengthened nickel-copper alloy that shares the excellent corrosion resistance of Monel 400 but with significantly higher strength and hardness. This enhanced performance is achieved through the addition of aluminum and titanium, which allow the alloy to be strengthened by a specific heat-treatment process.

Our Product Offering Includes:

  • Size Range: 15 NB to 150 NB
  • Types: Seamless, Welded, Calibrated, and Redrawn
  • Wall Thickness: From 0.40 mm to 12.70 mm
  • Strict Tolerances: +/- 0.030, ensuring precision for your fabrication needs
We provide pipes in various sizes and thicknesses, ensuring we can meet the unique needs of every customer.
