Abstract
An earth-working implement of high carbon-high hardness steel wherein the globular shape of the sulfides is retained during the manufacturing process by the addition of strong sulfide-forming additives whereby the 'fracture toughness' in the rolling direction is substantially increased thereby resulting in a high strength implement possessing superior fracture resistance properties in all directions including the rolling direction.
