medium-carbon steels
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. 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. See high-carbon steels; low-carbon steels.
