Alloy K500
Introduction :
Alloy K500, commonly referred to as “K-Monel”, is a precipitation-hardenable, nickel-copper alloy with similar corrosion resistance to that of Alloy 400 but with greater strength.
Typical industrial applications for Alloy K500 include fasteners, springs, and chains for marine service, pump and valve components for chemical processing facilities as well as blades and scrapers used in pulp and paper production. Oil and gas production utilize
Alloy K500 for drill collars, instruments, pump shafts, impellers, and valves as well as for sensors and electronic components.
