Forgings Where, Why, How?
It then must be reheated before forging can continue. For example, a steel shaft 2 ft in diameter and 24 ft long may require four to six heats before final forged dimensions are reached. In open die forging of steel, a rule of thumb says that 50 lb of falling weight is required for each square inch of stock cross-section.
