• Strict control since raw material selection process ensure constant alloy properties
• Refined metallographic structure
• Reduced tool wear due to reduced impurity levels and adjusted beta content
• Fine chips deriving from homogeneous lead dispersion all over the material microstructure
• Geometric tolerances tighter than specified in the norm EN 12164 traduce in high productivity ratios
• Every rod is inspected individually to ensure the required straightness; Maximum deviation from straightness allowed for ASBW hexagonal rods:
  - 0.6 mm localized over any 400 mm length
  - 1.5 mm over the whole rod length
  - Restrict control of the profile deviation by torsion (twist)
  - Uniformity of the drawn rod surface
  - Refined and adjusted chemical composition for the hexagonal profiles, to ensure product integrity, machinability and internal stress relieved characteristics
  - Homogeneity of the surface appearance, mechanical properties and diameter within and across bundles
  - Rod ends shaped to perfectly suit your automated machining process
  - Eddy current test on customer’s request

Types of end shaping

By standard, the ASBW machining rod is supplied with pointed and chamfered ends according to EN 12164.
Different combinations of rod ends finishing possible on customers request.

Straightness

The ASBW hexagonal machining rod is the ideal solution for your production process, offering high quality standards in terms of straightness in its entire length (L1), within the with across flats range from 10 mm to 50 mm. For hexagonal precision machining rods, we offer a gap for the entire deviation of 1,5 mm/m (h1) and a maximum local deviation of 0,6 mm/ ≤ 400 mm (h2 or h3).

ASBW drawn hexagonal rod for machining complies with EN 12164, strictly following the specifications for deviation of the profile by torsion “V”, in reference to the control surface, as illustrated bellow.

Corner radii for Hexagonal Rods

ASBW hexagonal machining rods are supplied with sharp edges only, over all the range of width across flats.

Packaging

Size range up to 10 mm
The rods are packed loose in a wooden box and protected with oiled paper (net weight of approx. 500 kg). Each box is strapped with 4 steel straps to ensure material integrity during shipping.

Size range above 10 mm
ASBW hexagonalmachining rods are supplied by standard in bundles either of approximately 1.000 kg or 500 kg. Different bundle weights are also possible upon costumer’s request. Each bundle is steel strapped three times on cardboard and both ends are protected with litter, to ensure the material integrity during the transportation.

Labeling

In order to ensure, the traceability according to NP EN ISO 9001:2015, each bale (wooden box or bundle) is marked with a label indicating the details mentioned below:

• customer
• number of customer’s order
• EN Standard of the material
• ASBW material code
• rod length
• ASBW’s PO number
• ASBW’s Quality Approval Seal
