Cracks: Longitudinal cracks, cracks, and cracks that appear on the wire surface.
Cracking (stitching): The surface of the wire is cracked by visible small transverse stripes that show a tongue or other shape.
Stratification: Partial or long division of the longitudinal direction of the steel wire
Scab (Landscape): Yellow bismuth oxide appearing on the wire surface, white lime
Pull marks: The apparent minor grooves or ribs that exist longitudinally on the surface of the wire, and those that are slight make the surface appear barely shiny.
Fold: The metal overlap along the length of the wire surface is now visible. It is often straight, but it is also curved or zigzag. In metallographic examination, iron oxide inclusions and decarburized layers are usually present in the folds.
Concave: Local depression on the surface of the wire.
Rust: Partial and overall oxidation of the wire surface.
Pitches: Dots or patches of pits that occur when the surface of the wire is heavily oxidized.
Slub: The length of the wire is cyclically uneven and its shape resembles bamboo.
Spiral: In the process of straightening the steel wire, a thread-like roll mark appears on the surface.
Oxidation: Oxidation of the surface of the steel wire in contact with high-temperature oxidation furnace gases produces a hard, brittle oxide.
Oxide film: A thin layer of dense oxide is formed on the surface of the steel wire. This oxide is generally not easily broken. It can only partially peel off when it is bent or deformed.
Oxidation: The surface of the wire produces a very thin layer of oxide tightly attached to the wire surface under conditions of bright heat treatment.
Decarburization layer: When the steel wire is heated, due to the role of carbon in the gas medium and the steel layer, the carbon content in the surface layer is reduced. This phenomenon of reduced surface carbon content is called decarburization.
Graphite Carbon: Part or all of the carbon in the steel is precipitated in a free state. This free carbon is stony carbon.
