Surface Quality ：
The surface of the steel wire shall be smooth and free from defects such as cracks, rust, folds, knots, etc. which may adversely affect the use, but shall permit the presence of an anisotropic scale and individual scratches and pits not exceeding one half of the dimensional tolerance.
Decarburization layer：
(Ferrite + transition layer) depth of not more than hexagonal wire nominal distance of 1.0% of the side,
Delivery Method ：
The wire is delivered as a coil
