ASTM A1

ASTM A1 is a standard created by the American Society for Testing and Materials that specifies the requirements for carbon steel wire used in making machine springs. It outlines the chemical composition, ductility, tensile strength, and other properties to ensure quality and consistency. This wire is typically cold-drawn, meaning it is shaped and strengthened by pulling it through dies at room temperature. ASTM A1 ensures that the wire is suitable for producing durable springs used in machinery, automotive parts, and various industrial applications, guaranteeing reliable performance and safety.
