A: SWCH grades, as found in JIS G3539, describe the cold-drawn wire (finished product). SWRCH grades, as found in JIS G3507, describe the hot-rolled wire rod (raw material).

: The cold-working process improves the grain structure, making the final fastener stronger. 🛠️ Technical Specifications jis g3539 pdf

The JIS G 3539 standard serves as a cornerstone for ensuring the reliability of metallic materials in sectors ranging from automotive to general engineering. Unlike general-purpose spring steel, the materials specified under JIS G 3539 are specifically engineered for "cold-working"—a process where metal is shaped at room temperature rather than by heat.
