Most grades under JIS G3539 require a specialized heat treatment (spheroidize annealing) to convert brittle iron carbides into spherical shapes. This drastically improves cold-formability and extends tool life. 4. Dimensional Tolerances and Surface Quality

: It covers steel wires intended for high-speed cold forging and heading processes, where the material must withstand significant deformation without cracking. Common Grades :
Do you need (like ASTM or DIN) for cross-referencing?
Enhances hardenability and strength while aiding forgeability.
As shown, while JIS G3507 covers the raw material in the form of wire rods that are hot-rolled in a steel mill, JIS G3539 governs the finished, cold-drawn wire that is ready to be fed into a cold heading machine for part fabrication. This distinction is crucial for professionals involved in the supply chain—from steel mills to part manufacturers.
Q: What is the significance of JIS G3539 in the construction industry? A: JIS G3539 ensures that steel wires used in prestressed concrete structures meet the necessary strength, durability, and safety requirements, promoting safety, quality control, and international trade.
Wire is bent 180° around a mandrel of equal diameter. No cracks are allowed.
(Carbon steel wires for cold heading and cold forging) defines the technical specifications for manufacturing and testing steel wires used in the cold forming industry. It covers wire processed from carbon steel, specifically designed to withstand the stress of shaping metals without pre-heating. Scope of Application
The standard classifies carbon steel wires into distinct grades based on chemical composition. The primary grading system typically tracks closely with standard carbon levels, optimizing formability and heat-treatment response.
Carefully balanced to ensure the wire can be fed into heading machines without snapping, while not being so stiff that it damages the tooling.
The standard is a critical industrial specification published by the Japanese Standards Association (JSA). It governs the requirements for carbon steel wires used in cold heading and cold forging applications. Manufacturers worldwide utilize this standard to produce high-quality fasteners, bolts, nuts, and complex automotive components without the need for hot shaping.
