The sample was crated for Charpy test as per ASTM-E23, and for Rockwell hardness test as per ASTM-E18.In this work EN8 a grade of medium carbon steel is used. The composition of this EN8 steel is shown in the table below. The specimen was taken in the form of square bars 14 脳...
The result of the case study reveals that hot forging has increased the dimensional accuracy by 11.15%, overcoming the spring back effect. Also, a significant reduction in porosity (54.28%) and increment in surface hardness (15.66%) are observed for hot forged EN8 flats in comparison to cold...
