Product Description

 

Forging where in the material is hammered according to the customers sizes & requirements is a process in which the ingot is heated in the furnace & then forged. the forging process help in cohesiveness and strength by elongation of the grain structure, which results in material having much higher load bearing capacities as compare to casted material.heat treatment is done in normalizing / annealing furnace and forgings are ultrasonically tested thereafter.we have the capacity to forge a single piece up to 7000 kg. in plain carbon steel such as m. s., class-2, class-3, en-8, en-9 & en-42, en-31, en-19, en-24, en-41b, en-353, en-25, en-18, etc. These forged rolls are basically used for rolling purpose in industries where grinders, channels, angles are manufactured.
