What is Composition of Medium-carbon Steel - Definition

Medium-carbon steel has approximately 0.3–0.6% carbon content. For example, a 1040 steel is a plain carbon steel containing 0.40 wt% C. Composition of Medium-carbon Steel

Medium-carbon steel has approximately 0.3–0.6% carbon content. These alloys may be heat-treated by austenitizing, quenching, and then tempering to improve their mechanical properties. They are most often utilized in the tempered condition, having microstructures of tempered martensite. Medium-carbon steel balances ductility and strength and has good wear resistance. This grade of steel is mostly used in the production of machine components, shafts, axles, gears, crankshafts, coupling and forgings, could also be used in rails and railway wheels and other machine parts and high-strength structural components calling for a combination of high strength, wear resistance, and toughness.

For example, a 1040 steel is a plain carbon steel containing 0.40 wt% C. Typical uses of this type of steel include machine, plow, and carriage bolts, tie wire, cylinder head studs, and machined parts, U-bolts, concrete reinforcing rods, forgings.
