Casting steel and forging steel are two different processes. Casting steel is the steel for pouring castings.Cast steel refers to a type of steel casting produced by casting methods.
Due to metal deformation and recrystallization, the original coarse dendrites and columnar grains are transformed into equiaxed recrystallized structures with finer grains and uniform sizes in the casting structure, resulting in the original segregation, porosity, pores, slag inclusions, etc. in the steel ingot Compaction and welding, the organization becomes tighter, and the plasticity and mechanical properties of the metal are improved.Cast steel is mainly used to manufacture parts with complicated upper knot shapes, difficult to forging or cutting forming, and requiring higher strength and plasticity.
Forged steel refers to various forging materials and 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 structure and structure of the same part, with good mechanical properties and uniform grains. Important laborious workpieces must be forged. Casting will cause structural segregation and structural defects. Of course, casting also has its own advantages. The advantage is that it is not easy to open the mold for forming complex workpieces, and only casting is used.
