Cold heading processing sets strict requirements on the ductility, dimensional accuracy and batch stability of raw materials. With years of experience in producing cold heading steel wire, Aotian Steel takes SWCH22A as one of its mature core products, which has won recognition from numerous customers for its reliable overall performance.
As a standard low-carbon cold heading steel, SWCH22A adopts a well-proportioned chemical composition. Harmful impurities are strictly limited to ensure high material purity. Featuring moderate initial hardness and outstanding ductility, the steel wire resists cracking and peeling during conventional cold heading and cold extrusion. It is suitable for forming various workpieces and fully adapts to large-scale continuous production.

Adopting mature rolling and controlled cooling technologies in production, the finished wire rod has precise dimensional tolerance, smooth surface, uniform internal metallographic structure and well-controlled decarburized layer. The performance of each batch remains consistent with stable and reliable quality.
SWCH22A has a wide range of applications. It is used to produce common bolts, rivets, pins, general hardware accessories and more, covering machinery manufacturing, hardware processing, daily fastener production and other fields.
Aotian Steel always adheres to strict quality criteria. We provide products of standard specifications, and support customized services as well as complete quality inspection documents. Thanks to reliable product quality and stable supply capacity, SWCH22A has become a well-recognized cold heading steel wire in the market, delivering solid support to the production and operation of all partners.
