Barra Hexagonal 12L14 / Hexagonal Steel Bar 12L14 / Trefilado Hexagonal 12L14
12L14 - COLD DRAWN ROUND ROD
Cold Drawn Round 12L14 Carbon Steel Bar/Rods are best known for their excellent machinability due to its added Lead content.
12L14 Cold Drawn Steel Rods are frequently used to fabricate high speed machinery. It has very high machinability and low weldability, but it can be bent, riveted or crimped.

4..Advantages of cold drawn steel bar:
1.It can remove the Size and Section which provides Tighter tolerances which Reduces machining losses.
2.It can remove the Steel Surface Finish which Reduces surface machining & improves quality.
3.It can remove the Straightness which Facilitates automatic bar feeding in CNC.
4.It can increase the Mechanical Properties which Can reduce the need for hardening.
5.It can improve the Machinability and Productivity which Enables higher machining feeds, high tool life, yield & speeds and improved machined finish.
5.Delivery time : 7days for stocks, within 30 days for new production ones.
