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 have lower carbon content than cast steel flanges and are not easy to rust. Forgings have better streamlined shapes, denser structures, and better mechanical properties than cast flanges;
An improper forging process will also cause large or uneven grains and hardening cracks, and the cost of forging 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 a cast flange and the forged flange is distinguished from the production process. For example, the centrifugal flange is a kind of cast flange.
