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