(Specification)Standard Specification for Steel Wire, High Tensile Strength, Cold Drawn
Standard Specification for Steel Wire, High Tensile Strength, Cold Drawn
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.
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 shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
