medium-carbon steels
Group of carbon steels designated by American Iron and Steel Institute numerical classification as AISI 1029, 1030, 1034, etc., up to AISI 1053, for a total of 16 grades. They are often selected where higher strength is required. Most commonly used steels for machined components.

They are often selected where higher strength is required. Most commonly used steels for machined components. Composition of medium-carbon steels is: 0.25 to 0.55 percent carbon, 0.30 to 1.00 percent manganese, 0.040 percent (maximum) phosphorus and 0.050 percent (maximum) sulfur.
