A steam hammer is a large industrial machine that uses steam power to drive a heavy hammer. It is primarily used for forging metal, shaping it into desired forms by delivering powerful blows. The steam pressure is controlled to lift and drop the hammer, allowing for precise and forceful impacts on the material being worked. Invented in the early 19th century, the steam hammer revolutionized metalworking and manufacturing. It enabled faster production and improved the quality of forged products. This innovation played a significant role in the development of industries such as railroad construction and shipbuilding.
