Carbon is used to control mechanical properties of steel

We can provide Anthracite, Recarburaizers, Petroleum coke, Dryed Anthracite, Metallurgical/Foundry coke.
Carbon determines most of the mechanical properties of steel. Changing the percentage of Carbon can affect the strength and hardness characteristics of steel.
