ASTM A493-95(2004)

Standard Specification for Stainless Steel Wire and Wire Rods for Cold Heading and Cold Forging

ABSTRACT
This specification covers cold-finished and hot-finished stainless steel wire and wire rods for cold heading or cold forging for applications, such as fasteners, where corrosion resistance is a factor. The steel shall conform to the required chemical composition requirements. The material shall also conform to the requirements as to mechanical properties. All austenitic grades in the annealed condition or annealed and lightly drafted condition shall be capable of passing the criteria set by this specification.
SCOPE
1.1 This specification covers cold-finished and hot-finished stainless steel wire and wire rods for cold heading or cold forging for applications, such as fasteners, where corrosion resistance is a factor.  
1.2 The values stated in inch-pound units are to be regarded as the standard. The SI equivalents are in parentheses and may be approximate.
