86L20 Cold Drawn Steel Bar
Cold drawn 86L20 steel bar is a low carbon, nickel-chromium-molybdenum steel with an addition of lead. The grade, like 8620, is still commonly used for carburizing or surface treatment. Cold drawn 86L20 steel bar has added machinability in comparison to standard 8620, for parts that require higher production, or more machining prior to carburizing or surface treatment. Eaton Steel Bar Company stocks many diameters of 86L20 cold drawn steel to meet the market demands.
