EN8 Round Bar: Properties, Hardness and Applications
EN8 Round Bar: Properties, Hardness and Industrial Applications EN8 round bar is a medium-carbon engineering steel used for parts that need better strength, wear resistance, and machinability than ordinary mild steel. It is commonly linked with BS 970 EN8 / 080M40 and is widely used in shafts, axles, pins, bolts, studs, gears, spindles, bushes, collars, and general machined components. For engineering buyers, EN8 is often selected when mild steel is not strong enough but alloy steel such as EN19 is not required. It offers a practical balance of strength, machining performance, heat-treatment response, and cost efficiency for general industrial applications.
