20# Carbon Steel Plate
20# Carbon Steel Plate is a low-carbon steel characterized by a nominal carbon content of around 0.20%. This low carbon level ensures excellent weldability, high ductility, and good cold formability, making it easy to fabricate. While it offers lower strength than medium-carbon steels, it maintains good toughness and is typically used in the as-rolled or normalized condition. 20# plate is extensively used for general structural parts, machine components that require case hardening (carburizing), non-critical pressure parts, and various mild applications in construction and engineering where ease of processing is prioritized over high strength.
