With the correct information on its status, scope, and material grades, professionals can confidently navigate the transition to newer standards while ensuring that the core material properties and quality benchmarks are met. This comprehensive overview positions you to access the standard legally and apply its technical details effectively in your industrial operations.
Other less official platforms can be used for research, but they are not authoritative sources and may not provide certified copies.
In the precision-driven world of fastener manufacturing and industrial forging, adherence to stringent material standards is non-negotiable. is a critical Japanese Industrial Standard (JIS) that specifies the requirements for carbon steel wires intended for cold heading and cold forging applications. These wires are the backbone for producing bolts, nuts, rivets, tapping screws, and various other machined components.
Acts as a deoxidizer; kept low in heading grades to maintain softness. Manganese (Mn): Enhances hardenability and strength.
Optimized to ensure the wire does not snap during feeding. jis g3539 pdf
Compresses a specimen axially to detect surface seams or splits.
If you are in the process of sourcing, ensure your supplier provides certifications confirming compliance with the latest standard. If you'd like, I can help you: Compare specific SWCH grades (e.g., SWCH10A vs. SWCH20A).
: It guarantees that finished parts like tapping screws and rivets can withstand the stresses of their intended applications without cracking or failure.

JIS G3539:1991 is a withdrawn Japanese Industrial Standard that once specified the requirements for processes. However, the standard is no longer in active use.
The primary use is the production of fasteners such as screws, bolts, and nuts. In the precision-driven world of fastener manufacturing and
Although the standard is withdrawn, understanding the material requirements is valuable. The following data from the withdrawn standard provides a technical baseline for these materials.
The standard includes several grades of carbon steel wire, often designated with the (Steel Wire for Cold Heading) prefix. Common grades specified under this standard include:
High percentages indicate excellent ability to deform without splitting.
Low carbon steels, often used for rivets or components requiring high ductility.
