specifically specifies the requirements for Low-carbon steel wires, annealed . These are not high-tensile wires used for springs or cables. Instead, they are soft, ductile wires produced by annealing (a heat treatment process) low-carbon steel rods. jis g3539 pdf
If you are looking for a , it is essential to understand that while older versions (like 1991) are often referenced, the standard governs critical material properties like chemical composition, mechanical strength, and surface quality. 1.

Let’s break down JIS G3539 (now technically superseded by or integrated into newer standards like JIS G3532-3) and why this specification is the gold standard for . Instead, they are soft, ductile wires produced by
The standard also mandates that the wire must be coiled around a mandrel equal to its own diameter without showing cracks.
The wire is often designated with the prefix "SWCH" (Steel Wire for Cold Heading). Common grades include SWCH 10A , SWCH 12A , and SWCH 45K , which vary based on carbon content and manufacturing process (e.g., "A" for aluminum-killed steel, "K" for killed steel).
The standard specifies tensile strength and area reduction requirements. These ensure the wire is soft enough to be formed but strong enough to function as a fastener.
