The production process of forging flange: The production process is mainly divided into forging and casting.
Cast flange and forged flange
The cast flange has accurate shape and size, small processing volume and low cost, but has casting defects (pores, cracks, inclusions); the internal structure of the casting is poor in streamline (if it is a cutting part, the streamline is worse);
Forged flanges generally have lower carbon content than cast flanges and are not easy to rust. Forgings are streamlined, have a denser structure, and have better mechanical properties than cast flanges;
Improper forging process will also cause large or uneven crystal grains, hardening cracks, and forging costs higher than cast flanges.
Forgings can withstand higher shear and tensile forces than castings.
