These values are approximate, as precise tensile strength depends on the wire diameter and processing condition.

The standard distinguishes between different types based on processing and application:

Each type has slightly different annealing requirements and surface quality standards. Only the provides the full specification table. jis g3539 pdf

Steering knuckles, engine pins, and specialized brackets.

When sourcing materials globally, manufacturers often map JIS G3539 to alternative international designations. While not always identical, the following standards offer comparable performance for cold heading applications:

Below is a general breakdown of the chemical element limits mandated under the standard: Regulatory Control Limit Impact on Cold Forging Controlled from low to medium levels Determines core hardness and tensile strength. Silicon (Si) Kept low (typically Minimizes work hardening during processing. Manganese (Mn) Controlled strictly for uniform distribution Enhances structural toughness and hardenability. Phosphorus (P) Strictly capped (typically Excess causes cold shortness and cracking. Sulfur (S) Strictly capped (typically Excess creates non-metallic inclusions and failure points. 3. Mechanical Properties and Workability These values are approximate, as precise tensile strength

The JIS G3539 standard covers a wide range of steel wires, including:

The standard strictly controls the chemical content to ensure cold heading performance. While the exact numbers are protected by copyright, the general requirements are:

The wire must be free from harmful flaws like seams, cracks, or rust that could lead to fastener failure. Tolerances on diameter and ovality are stringent, typically specified in the standard (e.g., as discussed in related JIS G3539 documentation) to ensure the wire fits correctly into automatic headers.
