Advantages and disadvantages of cast flange and forged flange

  The shape and size of the casting blank are accurate, the machining amount is small and the cost is low, but there are casting defects (porosity, crack and inclusion); the internal structure streamline of the casting is poor (if it is a cutting part, the streamline is worse);

  Forged flange is generally lower carbon content than cast flange and is not easy to rust. Forging has good streamline, compact structure and better mechanical properties than cast flange;

  If the forging process is not proper, there will be large or uneven grains, hardening cracks, and the forging cost is higher than that of casting flange.

  Forgings can bear higher shear force and tensile force than castings.

  The advantages of casting are that it can produce more complex shape and lower cost;

  The forging has the advantages of uniform internal structure and no harmful defects such as pores and inclusions in the casting.
