鍛鋼和鑄鋼主要是鋼材的鍛造工藝，加工形式上不同：鑄鋼用以澆注鑄件的鋼。鑄造合金的一種。鑄鋼分為鑄造碳鋼、鑄造低合金鋼和鑄造特種鋼三類。

Forged and cast steel are mainly the forging process of steel, which are different in the form of processing: cast steel is used to cast the cast steel. A kind of cast alloy. The cast steel is divided into three types: cast carbon steel, cast low alloy steel and cast special steel.

鑄鋼是指采用鑄造方法而生產(chǎn)出來的一種鋼鑄件。鑄鋼主要用于制造一些形狀復(fù)雜、難于進行鍛造或切削加工成形而又要求較高的強度和塑性的零件

Cast steel is a kind of steel castings produced by the casting method. Cast steel is mainly used to make parts of complex shape, difficult to be forged or machined and required for high strength and plasticity.

鍛鋼 ：鍛鋼是指采用鍛造方法而生產(chǎn)出來的各種鍛材和鍛件。鍛鋼件的質(zhì)量比鑄鋼件高，能承受大的沖擊力作用，塑性、韌性和其他方面的力學性能也都比鑄鋼件高，所以凡是一些重要的機器零件都應(yīng)當采用鍛鋼件

Forged steel: Forged Steel refers to all kinds of forged and forgings produced by forging. The quality of forged steel is higher than that of steel castings, and it can bear great impact force. The mechanical properties of plasticity, toughness and other aspects are higher than those of steel castings, so all important machine parts should be forged steel parts.

鑄造是液態(tài)成型，而鍛造是塑性變形過程，鍛造成型工件可以改善組織內(nèi)部結(jié)構(gòu)，機械性能好，晶粒均勻，重要吃力工件必須鍛造，鑄造會造成組織偏析，組織缺陷，當然鑄造有他的好處，成型復(fù)雜工件鍛造不易開模，所以采取鑄造。

The casting is liquid molding and forging is the process of plastic deformation, forging workpiece can improve the internal structure, good mechanical properties, uniform grain, important difficult jobs must be forging, casting can cause segregation defects, of course, have cast his good, not easy to mold forging forming of complex workpiece, so take casting.
