1.1 This specification covers two finishes of round, metallic coated, hard-drawn, carbon steel spring wire having properties and quality for the manufacture of mechanical springs and wire forms that are not subject to high stress or require high fatigue properties.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values stated in SI units are for information purposes only.


This specification covers round, metallic coated, hard-drawn, carbon steel spring wire having properties and quality for the manufacture of mechanical springs and wire forms that are not subject to high stress or require high fatigue properties. The steel specimens shall be either ingot cast or strand cast and shall be cold drawn. Prior to cold drawing, the specimens shall be furnished in to three types of metallic coating: aluminum coating, zinc coating and zinc-aluminum-mischmetal alloy coating categorized as Type A, Type B, and Type C, respectively. The steel shall undergo heat analysis and product analysis wherein the materials shall conform to the requirements of chemical compositions of carbon, manganese, phosphorus, sulfur, and silicon. Tension test, wrap test and metallic coatings test shall be performed wherein the specimens shall conform to the values of tensile strength, Mandrel diameters and minimum weight of aluminum, zinc or zinc-aluminum-mischmetal alloy per unit area of uncoated wire surface.
