The difference between steel forging and cast steel is mainly reflected in the difference in the processing technology (forging and casting) of steel. Forging of steel forging is a plastic deformation process, while casting is liquid forming.

Steel forging refers to various forgings and forgings produced by forging methods. The plasticity, toughness, and other mechanical properties of steel forgings are higher than those of steel castings, and they can withstand greater impact force. Therefore, some important machine parts are made of steel forgings.
Compared with Steel forging, steel casting refers to a kind of steel casting produced by the casting method, which is a kind of casting alloy. Cast steel can be divided into three categories: cast carbon steel, cast low alloy steel, and cast special steel. Cast steel is mainly used to manufacture some parts with complex shapes, which are difficult to be forged or formed by cutting and require high strength and plasticity.
Through the above introduction and analysis of the difference between Steel forging and cast steel, hope it helps you.
