What is 12L14 Cold Drawn Steel Bar?

Cold-drawn or cold finished 12L14 steel bar is a resulfurized and rephosphorized carbon steel. This grade is considered free machining, having excellent machinability due to its added sulfur, phosphorus, and lead. Due to its low carbon, this material has lower strength than other cold drawn grades. Eaton Steel Bar Company stocks several diameters of this grade to meet your demands quickly. We also supply 12L14 cold drawn bar to various industries like aerospace, automotive, and more.
