High Carbon Plates
High Carbon Steel Plates contain carbon levels between 0.40% and 1.00%, creating a fine pearlite structure that delivers exceptional hardness and strength. While these plates are significantly tougher than mild steel, the higher carbon content makes them more brittle and less ductile. Jitu Milan Steels provides these plates as an economical solution for projects requiring maximum material hardness.
Due to their composition, high carbon steel is one of the most vital metals in heavy construction and industrial tool manufacturing. However, users should account for reduced weldability and impact toughness compared to lower-carbon alternatives. We ensure our high carbon plates meet precise specifications to balance extreme surface hardness with structural reliability.
We deal in all Thickness is from 2mm-600mm as per client's requirements.
