The steel may be made by any commercially accepted steel-making process. The rod to be used in the manufacture of wire furnished to this specification shall be in accordance with Specification A510/A510M.
The finished wire shall be free from detrimental pipe and undue segregation.
The wire shall be cold drawn to produce the desired mechanical properties.
Type 1 wire shall be directly drawn from either as-rolled rods or from air patented rods or wire to the final wire diameter.
Type 2 wire shall be drawn from either patented rod or patented wire to the final wire diameter. Air patenting is not allowed.
Type 2 wire may be substituted for Type 1 wire. Conversely. Type 1 wire may not be substituted for Type 2 wire.
The method of patenting, and in particular the method utilized for controlled cooling, can be designed to optimize the microstructure and mechanical properties of either patented wire rod or patented wire, as well as of wires drawn from either of these. Because patenting is performed in a linear manner rather than in a coiled or serpentine manner, the uniformity of microstructure and mechanical properties along the patented wire or patented wire rod length is improved compared to that existing in either of these prior to palenting.
The maximum affected depth of decarburization shall not exceed 2.0 % of the wire diameter or 0. 15 mm [0.006 in.], whichever is less. The maximum average partial decarburiza tion depth shall not exceed 1.5 % of the wire diameter
Orders for steel wire under this specification shall contain the following information:
1 Quantity (weight in lbs, or mass in kg)
2 Name (music steel spring wire) and type (Type 1 or Type 2) of material
3 Diameter
4 Finish
5 Packaging
6 ASTM designation and year of issue.
option to specify additional requirements
1 Requirements for certifications, heat, or test reports
2 Special packing, marking, and loading requirements
1 The coil, reel or spool mass, dimensions, and the method of packaging shall be agreed upon between the manufacturer and purchaser.
2 A tag shall be attached securely to each coil of wire with identifying information as agreed upon by the purchaser and manufacturer.
3 Unless otherwise specified in the purchaser's order, packaging, marking, and loading for shipments shall be in accordance with those procedures recommended by A700.
