Forged Crane Wheel offers uniformity of composition and structure. Forging results in metallurgical recrystalisation and grain refinement as a result of the thermal cycle and deformation process. This strengthens the resulting steel product part particularly in terms of impact and shear strength. Forged steel is generally stronger and more reliable than castings and plate steel due to the fact that the grain flows of the steel are altered, conforming to the shape of the part. Advantages of forged crane wheel:
· Generally tougher than alternatives.
· Will handle impact better than castings.
· The nature of forging excludes the occurence of porosity, shrinkage, cavities and cold pour issues.
· The tight grain structure offers great wear resistance without the need to make products"superhard" We have found that, on a blank HRC3842 forged grinder insert wear/wash is about the same as a high alloy HRC46-50 grinder insert.
