    Abstract

    This specification covers round, uncoated, high tensile strength, cold-drawn steel spring wires having properties and quality suitable for the manufacture of mechanical springs and wire forms subject to high static stresses or infrequent dynamic load, or both. The steel shall be made by any commercially accepted steel making process. The steel shall either be ingot cast or continuous strand cast. The finished wire shall be free from detrimental pipe and undue segregation. The wire shall be cold drawn to produce the desired tensile strength. The wire finish shall be suitable for forming or coiling. It is not intended that this material be furnished with a metallic coating. Heat and product analysis shall be conducted wherein the material shall conform to the required chemical composition values of carbon, manganese, phosphorus, sulfur, and silicon. The material shall undergo tensile and wrap tests. The steel shall have fine pearlite microstructure and the wire surface shall not exhibit imperfections.

    This abstract is a brief summary of the referenced standard.

    1. Scope

    1.1 This specification covers round, uncoated, high tensile strength, cold-drawn steel spring wire, having properties and quality suitable for the manufacture of mechanical springs and wire forms subject to high static stresses or infrequent dynamic load, or both.

    1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.
