UNS G12150 ASTM 1215 Free Cutting Cold Drawn Steel Bar
Cold drawn 1215 steel bar is resulfurized and rephosphorized carbon steel. This grade is considered free machining, having excellent machinability due to its added sulfur, phosphorus. This grade, also referred to as "screw stock", is heavily utilized for automatic screw machine operations. It's also ideal for parts that require heavy machining and bright finishes. 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 1215 cold drawn bar to various industries like construction, automotive, and more.
Applications
Typical applications for this grade include pins, couplings, fittings, and bushings.

4.Tolerance of our cold drawn steel bars: h8,h9,h10,h11 or as required
5.Straightness of our cold drawn steel bars: Max 0.5mm/m
6.Advantages of cold drawn processing:
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.
7.Packing of cold drawn steel bars:
a. Surface put anti-rust oil
