Difference between forging and casting


The production process of flange is mainly divided into forging, casting, cutting and rolling.

Cast flange blank shape and size accurate, small processing quantity, low cost, but there are casting defects (pores, cracks, inclusion).Casting internal organization is less streamlined (or worse if it is a cutting part).

Forging flange is generally lower in carbon content and less prone to rust than casting flange, the forging is more streamlined and compact, and the mechanical properties of tungsten steel reamer are better than casting.Improper forging process will also appear large or uneven grain, hardening crack phenomenon, forging cost is higher than the casting flange.
