ASTM A493:16 pdf download.Standard Specification for Stainless Steel Wire and Wire Rods for Cold Heading and Cold Forging.
3.1 .8 Coil size (inside and outside diameter),
3.1 .9 Special requirements. and
3.1.10 Supplementary requirements.
4. General Requirements for Delivery
4.1 In addition to the requirements of this specification, all requirements of the current editions of Specification A555/ A555M shall apply. Failure to comply with the general requirements of Specification A555/A555M constitutes nonconformance with this specification.
NOTE 1—Atypical ordering dcscription is as follows: 5(X)0 lb (2268 kg) 0.225 in. (5.72 mm) round Type 305 cold heading wire, lightly drafted, copper coated. 32 in. (813 mm) max OD—22 in. (559 mm) mm ID. coils, ASTM Specification A493 — XX. End use: hex head machine bolts.
5. Manufacture
5. 1 Heat Treatment:
5.1.1 Austenitic grades shall be annealed at 1800°F (980°C) minimum, so that grain boundary carbides enter into solution, and rapidly quenched to prevent grain boundary precipitation of carbides that would cause susceptibility to intergranular corrosion. See Supplementary Requirements.
5.1.2 Ferritic and marlensitic grades shall be annealed to meet the requirements for mechanical properties.
5.2 condition:
5.2.1 Wire shall he furnished in one of the following conditions:
5.2.1.1 Lightly drafted (normal condition and need not be specified if this is condition desired),
5.2.1.2 Annealed, or
5.2.1.3 Drafted to a specified tensile strength range (as agreed upon between purchaser and producer).
5.2.2 Rods shall he furnished in the annealed condition, scale removed.
5.3 coatings and Lubricants:
5.3.1 Coatings are necessary for most cold-heading or forming operations. An electroplated copper coating is often used. The following coatings may be specified: copper. lime, or special (as agreed upon between purchaser and producer).
5.3.2 Lubricants are applied over the coating during the final drafting operation performed by the producer.
