Monel K500 Round Bar , ASTM B865 UNS N05500 Nickel Alloy Rod

ASTM B865 is a standard specification for precipitation-hardening nickel-copper alloys such as MONEL K500. This specification covers MONEL K500 round bars that are hot-worked or cold-worked and precipitation hardened. The bars are available in various sizes and shapes, and are typically used in applications that require high strength and corrosion resistance.

MONEL K500 has a unique combination of properties that make it suitable for use in high-stress applications at both room temperature and elevated temperatures. The precipitation-hardening process used to manufacture MONEL K500 round bars involves heating the material to a specific temperature and then cooling it rapidly. This process creates a fine dispersion of precipitated particles in the material, which increases its strength and hardness. MONEL K500 round bars can be machined using conventional methods, but they are more difficult to machine than many other materials due to their high strength and hardness.

Applications

MONEL K500 is often used as a replacement for MONEL 400 in applications that require higher strength and hardness. However, it is important to note that MONEL K500 has lower ductility than MONEL 400, which can make it more susceptible to cracking under certain conditions.

Some examples of applications include:

• Pump shafts and impellers in seawater service
• Valve components and springs in corrosive environments
• Oil well tools, such as drill collars and subs
• Electronic components in marine environments
• Fasteners and fittings in chemical processing plants
