A36 A283 1008 4320 SS400 S235JR Q345 Hot Rolled Steel Plate 0.0218-2.11% Carbon for Industrial Applications
Carbon steel is an iron-carbon alloy with carbon content ranging from 0.0218% to 2.11%. Generally containing small amounts of silicon, manganese, sulfur, and phosphorus, these hot-rolled steel plates offer varying mechanical properties based on carbon content—higher carbon content increases hardness and strength while reducing plasticity.
