The cast flange has accurate shape and size, small processing volume, and low cost, but has casting defects (porosity, cracks, and inclusions); the internal streamline of the casting part is poor (if it is a cutting part, the streamline is worse);
Forged flanges generally have lower carbon content than cast flanges and are less prone to rust. The forged parts have a streamlined shape, denser structure and better mechanical properties than cast flanges.
Improper forging process can also cause large or uneven grains, hardening cracks, forging cost is higher than casting flange.
Forgings can withstand higher shear and tensile forces than castings.
The advantage of castings is that they can produce more complex shapes with lower cost;
The advantage of forgings is that the internal structure is uniform, and there are no harmful defects such as pores and inclusions in the castings;
The difference between the casting flange and the forging flange is different from the production process. For example, the centrifugal flange belongs to a type of casting flange.
