Description
20C8 Round Bars
20C8 Round Bars is an unalloyed low carbon grade. Components when carburized have a core strength range of 430-490N/mm² with the hard wear-resistant surface case. It is a popular case hardening steel grade for general engineering, readily machinable and weldable in its supply condition. 20C8 is low tensile steel suited for lightly stressed components.
Commonly used for general engineering lightly stressed applications that are subject to wear, 20C8 is suitable for applications such as collets, cams, rollers, bushes, spindles, and gears.
