Cast steel is the steel used for pouring parts, a kind of casting alloy.Cast steel is divided into cast carbon steel, cast low alloy steel and cast special steel.Cast steel refers to a type of steel casting produced by casting methods.Cast steel is mainly used to manufacture some parts with complex shapes, difficult to forge or cutting and forming, but require higher strength and plasticity.
Forged steel refers to various forgings produced by forging methods.The quality of forged steel parts is higher than that of cast steel parts, and can withstand large impact forces. The plasticity, toughness and other mechanical properties are also higher than those of cast steel parts. Therefore, forged steel parts should be used for all important machine parts.
Casting is liquid forming, while forging is a plastic deformation process. Forging shaped workpieces can improve the internal structure of the organization, with good mechanical properties and uniform grains. Important laborious workpieces must be forged. Casting will cause microstructure segregation and microstructure defects. Of course, casting also has its benefits. , Forming complex workpieces is not easy to open the mold for forging, so casting is adopted.
Both cast steel and forged steel have their own advantages and disadvantages, and they are also commonly used by people.
