AISI S7 steel was originally derived from the United States commercial brand Finkl DRX, is a kind of medium carbon chromium molybdenum alloy shock resisting tool steel. It’s characterized by a good comprehensive property like hardenability, high strength, toughness, tempering stability and oxidation resistance of temperature, is suitable for load tools or dies working under high temperature and high impact and hammer forging die manufacturing. This steel has a high hardness after forging, so it needs softening and annealing to reduce the hardness and facilitate cutting. The available forms of S7 steel including round bar, drill rod, rectangular bar, ground flat bar, square bar and plate
