The primary function of this standard is to provide a uniform classification system. It defines specific alloy designations (material numbers) and sets the limits for the chemical elements within those alloys. For instance, the standard covers alloys that bridge the gap between stainless steels and high-nickel alloys. By strictly defining the percentage ranges of elements such as Nickel (Ni), Chromium (Cr), Iron (Fe), Carbon (C), and additives like Silicon (Si) or Manganese (Mn), the standard ensures that a piece of metal designated as a specific alloy meets the performance characteristics expected by the design engineer.
