Standard Specification for Steel Wire, High Tensile Strength, Cold Drawn
STANDARD published on 15.8.2024
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

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.
