1045 steel is often used to manufacture large sprockets and steel gears for the paper industry and other processing industries. Coal, iron, rock, stone, gravel, and even cement are processed and transported every day using parts made from 1045. As a result, engineered systems such as moving systems, crushing systems, curing and drying systems handle enormous tonnages of raw materials while processing them into smaller, more refined, or mixed applications.
