41L40 Cold Drawn Steel Bar
41L40 steel bar is a Chromium-Molybdenum steel with a lead addition that is widely used due to its ability to maintain its physical properties, even after extended exposure to high working temperatures. It has high hardenability, high wear resistance, and excellent toughness. The addition of lead in this grade improves machinability. Eaton Steel Bar Company stocks many diameters of 41L40 cold drawn steel to meet the market demand. 41L40 can be heat treated and annealed.
