-No such difficulty in casting complex parts.
-No size limitations
-Comparatively easier than forging
Why use Forging?
Forged steel is stronger and more reliable than castings. Forged parts have higher tensile strength than cast parts. Forged parts also have higher fatigue strength. Forging is used because-
-Will handle impact better than cast one
-The nature of forging excludes the occurrence of porosity, shrinkage, cavities and cold pour issues.
-The tight grain structure of forgings making it mechanically strong. There is less need for expensive alloys to attain high strength components.
-The tight grain structure offers great wear resistance without the need to make products “superhard” We have found that on a blank HRC 38-42 forged grinder insert wear/wash is about the same as a high alloy HRC 46-50 cast grinder insert. The difference being an HRC 46-50 casting does not have the ductility to handle high impact grinding.
