Carbon Steel Precision Casting ZG230-450

Carbon Steel Precision Casting ZG230-450

Carbon content less than 1.35% (0.1% -1.2%), in addition to iron, carbon and silicon less limited, manganese, phosphorus, sulfur and other impurities, without other alloying elements. The property of carbon steel depends on the carbon content. The carbon content increases the strength of steel, increased hardness, ductility, toughness and weldability decrease. Compared with other types of steel, carbon steel is of the earliest use, low cost, wide property range, the largest use amount.
