20# Carbon Steel Coil/Strip
20# Carbon Steel Coil/Strip is a rolled thin-gauge product made from low-carbon steel with a nominal carbon content of around 0.20%. This low carbon level ensures excellent cold formability, high ductility, and superb weldability, making it ideal for processes like deep drawing and stamping. While offering lower strength than medium-carbon steels, it maintains good toughness. 20# coil/strip is widely used for manufacturing tubing, stamped parts, automotive panels, non-critical pressure vessel components, and various cold-formed items in engineering and construction where ease of fabrication and low cost are the main priorities.
