12L14 Steel Bar Stock: Free-Machining Alloy for Precision Parts

12L14 steel bar stock is one of the most widely used free-machining carbon steels, known for its outstanding machinability rating of 160%. This makes it an ideal material for producing intricate components that require strict dimensional tolerances and smooth surface finishes.

Superior Characteristics of 12L14 Steel

  • Enhanced Machinability – Lead and sulfur are added to improve cutting performance, reduce tool wear, and shorten production cycles.
  • Low Carbon Content – Provides excellent ductility and formability, although strength is lower compared to higher-carbon steels.
  • Versatile Forming – Can be bent, crimped, riveted, or machined into complex shapes with ease.
  • Dimensional Accuracy – Maintains tight tolerances, making it highly reliable for high-precision manufacturing.

Applications of 12L14 Steel Bar Stock

Because of its superior machinability and versatility, 12L14 steel is widely used across industries such as:

  • Automotive components
  • Oil and energy equipment
  • Medical instruments and devices
  • Fittings, bushings, and couplings
  • Fasteners, pins, and small precision parts
