4140 Steel Sheet 6mm Thickness Hot Rolled ASTM A36 Black Iron Plate 4x8 Inch for Building Structures
Zhengde Metal provides high-quality carbon steel products with carbon content ranging from 0.0218% to 2.11%. Carbon steel offers excellent mechanical properties where higher carbon content increases hardness and strength while reducing plasticity. Available in hot-rolled and cold-rolled variants, our steel plates are categorized into structural steel, tool steel, and free-cutting structural steel for diverse industrial applications.
