The difference between casting flange and forged flange
Flange production process is divided into forging and casting.
Forged flange is generally lower in carbon content than cast flange,less easy to rust,better streamlined forging,compact structure and better mechanical properties than cast flange.Improper flange forging process will also lead to large or uneven grains,hardening cracks and higher forging cost than casting flange.Forgings can withstand higher shear and tensile forces than castings.
The casting flange has accurate shape and size,small workload and low cost,but has casting defects (pore,crack,inclusion);the inner structure of the casting is poor streamlined (if it is a cutting part,the streamlined is worse);
The advantages of castings are that they can produce more complex shapes and lower costs.
The advantages of forgings are that the internal structure is uniform and there are no harmful defects such as blowhole and inclusion in the casting.
The difference between casting flange and forging flange can be distinguished from the production process,for example,centrifugal flange belongs to casting flange.
Centrifugal flange is a kind of flange produced by precision casting method.Compared with common sand casting,the structure of centrifugal flange is much finer and the quality is improved a lot.It is not easy to have loose structure,pore and trachoma.
