SS400 ASTM A36 A572 Gr50 S355 Wear Resistant Steel Plate 4x8FT with 0.5t-25t Roll Weight for Industrial Applications
Carbon steel is an iron-carbon alloy with carbon content ranging from 0.0218% to 2.11%. Also known as carbon steel, it typically contains small amounts of silicon, manganese, sulfur, and phosphorus. Generally, higher carbon content results in greater hardness and strength, but reduced plasticity.
