ASTM B983 N05500 Monel K-500 Nickel Alloy Round Bar for Marine, Offshore
ASTM B983 N0500 is a specification standard set by the American Society for Testing and Materials (ASTM) for nickel alloy bars. This specific grade, N0500, refers to a nickel-copper alloy known as Monel 500.
Monel 500 is a corrosion-resistant alloy that offers high strength and excellent resistance to a wide range of corrosive environments, including seawater and chemical environments. It is composed of approximately 65-70% nickel and 29-33% copper, with small amounts of iron, manganese, carbon, and silicon.
The ASTM B983 specification covers the requirements for Monel 500 bars in various sizes and shapes, including round bars, square bars, hexagonal bars, and rectangular bars. These bars are typically used in applications that require resistance to corrosion and erosion, such as marine and offshore equipment, chemical processing plants, oil and gas industry components, and heat exchangers.
The ASTM B983 N0500 standard provides guidelines for the chemical composition, mechanical properties, dimensions, tolerances, and testing requirements of Monel 500 bars. It ensures that the bars meet the necessary quality and performance standards for their intended applications.
It is always recommended to consult the specific ASTM B983 standard and work with reputable suppliers and manufacturers to ensure that the Monel 500 bars you are considering meet your exact requirements and specifications.
