Suppliers often provide material data sheets (MDS) complying with JIS G 3539. Conclusion
Low carbon steels, often used for rivets or components requiring high ductility.
The wires must meet specific mechanical benchmarks to ensure they can withstand the stresses of cold forging. Tensile Strength
JIS G3539 is a Japanese Industrial Standard that specifies the requirements for . "Cold heading" (also known as cold forging) is a manufacturing process used to form metal wires into specific shapes at room temperature—most commonly to produce screws, nuts, bolts, and other fasteners.
High-tensile bolts, screws, studs, and specialized nuts. jis g3539 pdf
Having access to the official is not just about documentation—it is about legal compliance, quality assurance, and international trade.
It mandates standard test methods, including tensile tests, upsetting tests (compressing a specimen to a fraction of its original height to check for cracks), and microscopic grain size evaluation. Equivalent International Standards

Complete Guide to JIS G3539: Standard for Carbon Steel Wires for Cold Heading and Cold Forging Suppliers often provide material data sheets (MDS) complying
JIS G3539 covers carbon steel wires that undergo severe plastic deformation at room temperature. The cold heading and cold forging processes require materials with exceptional formability to prevent cracking during high-speed manufacturing. Common Industry Uses
The American National Standards Institute provides access to foreign standards, including JIS documents, for legal download.
