The JIS G3539 PDF exclusively pertains to for the fastener industry. When sourcing steel pipes, one should never reference JIS G3539.

Surface defects are amplified during cold forging. A minor scratch can expand into a catastrophic split during heading. Therefore, JIS G3539 enforces stringent quality benchmarks. Surface Decarburization

A: It is used in the cold heading process to produce fasteners. A grade like SWCH12A is used to manufacture standard bolts and nuts without needing heat treatment, while SWCH45K is used for high-strength bolts that will be heat-treated after forming.

Professionals seek PDF versions of standards for several reasons: jis g3539 pdf

One of the first questions many engineers have is whether they can still rely on JIS G3539. The official status of the standard is (withdrawn). It was officially replaced on January 20, 2005 , and is no longer considered an active industrial standard by the Japanese Industrial Standards Committee.

| Element | Requirement (Typical Max) | | :--- | :--- | | Carbon (C) | ≤ 0.15% (low carbon grade) | | Manganese (Mn) | 0.30% – 0.60% | | Phosphorus (P) | ≤ 0.040% | | Sulfur (S) | ≤ 0.040% | | Silicon (Si) | ≤ 0.10% (some grades) |

Technical Report: JIS G 3539 - Carbon Steel Wires for Cold Heading and Cold Forging JIS G 3539:1991

It is important to know that JIS G3539:1991 has a withdrawn status. It was officially withdrawn and replaced by on January 20, 2005. While you may still find the PDF for historical reference, any technical work should refer to the newer standard for up-to-date specifications. A minor scratch can expand into a catastrophic

Each type has slightly different annealing requirements and surface quality standards. Only the provides the full specification table.

is the official Japanese Industrial Standard specifying the requirements for carbon steel wires for cold heading and cold forging [1]. This technical specification is critical for manufacturers, engineers, and quality control professionals in the automotive, construction, and fastener industries. Accessing and understanding the JIS G3539 PDF ensures compliance with precise chemical compositions, mechanical properties, and dimensional tolerances required for high-strength component manufacturing. Scope and Application of JIS G3539

Annealed at an intermediate or final stage to restore maximum ductility. DA: Drawn and subsequently annealed. Microstructural Integrity
