Wires must be free from seams, scratches, or cracks that could propagate during severe cold deformation.
JIS G3539 classifies the wires into several grades, generally designated by the acronym (Steel Wire Cold Heading) followed by a number indicating the approximate carbon content or grade type. Common grades specified under JIS G3539 include: jis g3539 pdf
JIS G 3539 is the Japanese Industrial Standard for Carbon Steel Wires for Cold Heading and Cold Forging Wires must be free from seams, scratches, or
The standard mandates minimal surface decarburization and a controlled grain size. Microstructural defects like seam lines, scratches, or scale pits are strictly restricted, as they act as stress concentrators and cause splitting during heading. 5. Manufacturing Process and Quality Control Microstructural defects like seam lines, scratches, or scale
: Ensuring that every batch of wire behaves predictably during the high-speed cold heading process.
