Yes. SWCH22A exhibits excellent welding performance due to its low carbon equivalent (Ceq) and low silicon content, provided that cold heading lubricants are thoroughly cleaned from the surface before welding.

Obtaining a legitimate PDF from the JSA or authorized resellers (e.g., Techno Standards, IHS Markit) ensures the user has the latest revision and avoids counterfeit or outdated copies often found on file-sharing sites. Cold heading requires the material to undergo severe
JIS G3539 covers carbon steel wires used primarily for manufacturing bolts, nuts, screws, rivets, and other complex parts through cold heading and cold forging processes. Cold heading requires the material to undergo severe plastic deformation without cracking. Therefore, the steel wire must possess high ductility, uniform microstructure, and excellent surface quality. Common industries utilizing this standard include:
