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.

| | Carbon Content (C) Approx. | Characteristics and Typical Applications | | :--------------- | :----------------------------- | :-------------------------------------------------------------------------------------------------------------------------------------------------- | | SWCH 10A | 0.10% | Excellent ductility and formability. Ideal for manufacturing simple, low-strength parts like rivets, washers, and small-diameter fasteners. | | SWCH 12A | 0.12% | A low-carbon grade offering a good balance of strength and formability for standard cold heading processes. | | SWCH 15A | 0.15% | Used for medium-strength fasteners, offering increased hardness over lower carbon grades while maintaining adequate cold formability. | | SWCH 17K | 0.17% | Provides enhanced mechanical properties suitable for automotive components where higher strength is required. | | SWCH 18A | 0.18% | A popular grade for general-purpose fasteners, offering good strength and consistent performance in cold heading. | | SWCH 22A (SWRCH22A) | 0.18-0.23% | A medium-carbon, aluminum-killed steel with excellent plasticity, superior weldability, and good workability for complex part geometries. | | SWCH 24K | 0.24% | Designed for applications requiring higher tensile strength, such as high-strength bolts and screws. | | SWCH 35K | 0.32-0.38% | A higher-strength grade for large-diameter bolts and critical structural fasteners, offering superior hardness and wear resistance. |

JIS G3539 establishes the specifications for carbon steel wires manufactured for cold working processes (heading and forging). The standard focuses on wire quality that can withstand high-pressure deformation without cracking or surface defects.

Standard thermal treatment providing an optimal balance for moderate forming.

The standard specifies carbon steel wires used for cold heading and cold forging applications [1]. These wires are essential raw materials for manufacturing fasteners, bolts, nuts, rivets, and complex automotive components without using heat. jis g3539 pdf

Detailed breakdowns for individual grades like SWCH 8R , SWRCH 12A , and SWCH 15R are available from the Gravity Group of Companies. JIS G3539 is a Japanese Industrial Standard that

Implement incoming quality controls (IQC) at your facility to confirm the wire meets the standard’s strict out-of-roundness and seam limits before feeding it into your cold forging machinery.

: The standard prefix for these materials.

Scale is removed via acid pickling, followed by phosphate coating to lubricate the wire during drawing.
