What is the difference between cast steel and cast forged steel? Release time：2020-10-21　　　　 Views

　　The anisotropy of mechanical properties of cast forged steel is not significant, which is better than that of forged steel. The results show that the longitudinal mechanical properties of rolled steel are generally slightly higher than that of steel castings of the same brand, while the transverse properties of rolled steels are lower than that of steel castings. The average mechanical properties of rolled steels are basically the same as those of good quality steel castings. For some high-tech products, the performance of materials in the three axis directions should be considered in the design process of parts. The above advantages of steel castings should be paid enough attention to.

　　Regardless of the weight and batch size of steel castings, they are easy to be made into parts with reasonable shape and internal contour, high rigidity, complex shape and insignificant stress concentration. For single piece or small batch production, wood pattern (pattern and core box) or polystyrene gasification pattern can be used, and the production preparation cycle is very short; for batch production, plastic or metal pattern can be used, and appropriate molding process is used to make the casting have the required dimensional accuracy and surface quality. These characteristics are difficult for forging.
