11L41 Carbon Steel Round Bar Stock

11L41 carbon steel round bar is a free-machining, heat-treatable grade designed for high-output production and precision machining. With carbon as its primary alloying element, it also contains controlled amounts of manganese, sulfur, and phosphorus, along with trace elements like molybdenum, chromium, aluminum, copper, and nickel. This unique composition gives it excellent machinability and reliable mechanical performance.

Key Properties of 11L41 Steel

High Machinability – Elevated sulfur content enhances chip-breaking, allowing it to machine even better than standard 1141 steel.
Heat Treatable – Can be hardened for applications that require improved strength and wear resistance.
Thermal Conductivity – Approximately 49.8 W/m·K, making it effective for thermal management in certain applications.
Density – Around 7.85 g/cm³, consistent with other carbon steels.
Cold Drawn Availability – Commonly supplied in cold-drawn form for tighter tolerances and smoother finishes.
