The cast
steel flange has an accurate blank shape and size, a small processing amount, and low cost, but has casting defects (pores, cracks, inclusions); the internal structure of the casting is poorly streamlined (if it is a cutting part, the streamlined form is even worse);
Forged steel flanges generally contain less carbon than cast steel flanges and are not easy to rust. The forgings are streamlined, have a denser structure, and have better mechanical properties than cast steel flanges;
Improper forging process will also cause large or uneven grains, and hardening cracks, and the forging cost are higher than that of cast steel 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 steel flanges and forged steel flanges is distinguished from the production process. For example, centrifugal steel flanges are a type of cast steel flanges.
