YB 5101 Music Spring Steel Wire

Introduce

round cold- drawn steel music spring quality wire, uniform in mechanical properties, intended especially for the manufacture of springs subject to high stresses or requiring good fatigue properties.

Chemical Composition

Supplying Size:

Diameter:0.05-8mm

Our Advantage

1. Stable linearity, good formability. Uniform and beautiful surface condition.

2. High plasticity and good fatigue resistance. And we provide Self-Inspection Reports and Raw-Material Test Certificates.

3. Professional anti-rust protective packaging. On time delivery, competitive price.

4. Large stock available, no MOQ requirement.

Surface Condition

The surface of the wire as-received shall be free of rust, excessive scale, die marks, pits, and scratches detrimental to the end application. Seams shall not exceed 2 % of the wire diameter or 0.15 mm [0.006 in.], whichever is less.

Surface Finish

Music wire is supplied with many different kinds of finish such as bright, phosphate, tin. and others. Finish desired should be specified on purchase orders.

Ordering Information

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

Manufacture

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.

Decarburization

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 decarburization depth shall not exceed 1.5 % of the wire diameter

Packaging and Marking

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 Practices A700.
