International Alloy Designation System

The International Alloy Designation System is a standardized way to identify different metal alloys, especially stainless steels and other special metals. It uses a combination of numbers and letters to describe the composition and type of alloy. For example, the designation "304" refers to a common stainless steel with specific amounts of chromium and nickel, indicating its quality and properties. This system helps engineers, manufacturers, and scientists quickly understand and communicate about metals, ensuring consistency and proper selection for various applications. It provides a clear, international framework for classifying complex metal compositions efficiently.
